| 1 | Efficient and stable planar all-inorganic perovskite solar cells based on high-quality CsPbBr3 films with controllable morphology显示文摘All-inorganic cesium lead bromide(CsPbBr3)perovskite is attracting growing interest as functional materials in photovoltaics and other optoelectronic devices due to its superb stability.However,the fabrication of high-quality CsPbBr3 films still remains a big challenge by solution-process because of the low solubility of the cesium precursor in common solvents.Herein,we report a facile solution-processed approach to prepare high-quality CsPbBr3 perovskite films via a two-step spin-coating method,in which the Cs Br methanol/H2 O mixed solvent solution is spin-coated onto the lead bromide films,followed by an isopropanol-assisted post-treatment to regulate the crystallization process and to control the film morphology.In this fashion,dense and uniform CsPbBr3 films are obtained consisting of large crystalline domains with sizes up to microns and low defect density.The effectiveness of the resulting CsPbBr3 films is further examined in perovskite solar cells(PSCs)with a simplified planar architecture of fluorine–doped tin oxide/compact Ti O2/CsPbBr3/carbon,which deliver a maximum power conversion efficiency of 8.11%together with excellent thermal and humidity stability.The present work offers a simple and effective strategy in fabrication of high-quality CsPbBr3 films for efficient and stable PSCs as well as other optoelectronic devices. | Xiaojing Wan Ze Yu Wenming Tian Fuzhi Huang Shengye Jin Xichuan Yang Yi-Bing Cheng Anders Hagfeldt Licheng Sun | 2020 | Journal of Energy Chemistry2020，29，7： | 6 |

| 7 | Bilayer metal halide perovskite for efficient and stable solar cells and modules显示文摘To reach the target of carbon neutral,a transition from fossil energy to renewable energy is unavoidable.Photovoltaic technology is considered one of the most prominent sources of renewable energy.Recently,metal halide perovskite materials have attracted tremendous interest in the areas of optoelectronic devices due to their ease of processing and outstanding performance.To date,perovskite solar cells(PSCs)have shown high power conversion efficiency up to 25.7%and 31.3%for the perovskite-silicon tandem solar cells,which promises to revolutionize the PV landscape.However,the stability of PSCs under operating conditions has yet to match state-of-the-art silicon-based solar cell technology,in which the stability of the absorbing layer and relevant interfaces is the primary challenge.These issues become more serious in the larger area solar modules due to the additional interfaces and more defects within the perovskite.Bilayer perovskite film composed of a thin low dimensional perovskite layer and a three-dimensional perovskite layer shows great potential in fabricating solar cells with high efficiency and stability simultaneously.In this review,recent advancements,including composition design and processing methods for constructing bilayer perovskite films are discussed.We then analyze the challenges and resolutions in deposition bilayer perovskite films with scalable techniques.After summarizing the beneficial effect of the bilayer structure,we propose our thinking of feasible strategies to fabricate high efficiency perovskite solar modules with a long lifetime.Finally,we outline the directions for future work that will push the perovskite PV technology toward commercialization. | Yanqing Zhu Min Hu Mi Xu Bo Zhang Fuzhi Huang Yi-Bing Cheng Jianfeng Lu | 2022 | Materials Futures2022，1，4： | 1 |

| 11 | Disturbance identification of electric field data observed by the CSES-01 satellite before earthquakes显示文摘Numerous studies have confirmed that electromagnetic disturbances before earthquakes can be observed by satellites.In this study,we use the C-value method that includes the acoustic whistle signature;pre-seismic ionospheric electromagnetic disturbance signals were acquired based on the CSES-01 satellite electric field data,and the maximum value of C in the earthquake preparation zones increased continuously from 2.0 three days before the earthquake and reached a maximum weight of 3.0 on the day of the earthquake,after the earthquake,it gradually decreased and recovered to about 2.0;its the C values fluctuated between-2 and 3,it is different from the C values range-2–12 of the previous seismic case study using the DEMETER satellite,which may be related to the orbital altitude and revisit period of the satellite.Then,the C values were normalized,and the time series analysis of the obtained θ values were done,and the results showed that:In the pregnant zone,the background variation of the disturbance amplitude θ is within 2σ,and the maximum disturbance amplitude of θ starts to increase gradually from the seventh period(one period of 5 days,i.e.,35–39 days before the earthquake),it reached 2σ by the fourth preseismic cycle(20–24 days before the earthquake),and then dropped sharply to about 1.5σ in the third pre-seismic cycle(15–19days before the earthquake),after two cycles of increase,the θ over the epicenter reached a maximum of 2.1σ at the time of the earthquake(combining the time of the earthquake and the satellite flight characteristics,the epicenter period is defined as January25-January 29,2020,and this defines the study time period line),and the θ decreases to within 2 times the standard range after the earthquake;The negative value of the disturbance amplitude θ in the central region of the pregnant seismic zone during the earthquake shows the transient energy release process.Through comparison,the θ values obtained by normalization based on the C-value method takes into account the variation of the background field,and the result can better reflect the energy change of the ionospheric field before the earthquakes. | Jianping HUANG Fuzhi ZHANG Zhong LI Xuhui SHEN Baiyi YANG Wenjing LI Zhima ZEREN Hengxin LU Qiao TAN | 2023 | Science China Earth Sciences2023，66，8： | 0 |
| 12 | Dissimilar laser welding of CrMnFeCoNi high entropy alloy and 316LN stainless steel for cryogenic application显示文摘The microstructure and mechanical properties of dissimilar laser beam welded joint between CrMnFeCoNi alloy and 316LN stainless steel was investigated.The results showed that the defect-free dissimilar joint was obtained by laser beam welding.The ultimate strength of the welded joints can reach∼90%of the base materials at both room and cryogenic temperatures.The deformation substructure mainly consisted of planar dislocation,the stacking faults and the dissociation of stacking faults into nanotwins.The volume fraction of the nanotwins was increasing at cryogenic temperature.The hardness fluctuates greatly in welded joint and the lowest hardness was located at fusion zone near the fusion line.The fracture of the welded joint was located at the fusion zone in consistence with the lowest hardness area.It is mainly attributed to the coarse grain and stress concentration at this area. | Jijun Xin Wei Wang Xiao Yang Mebrouka Boubeche Shanlin Wang Hengcheng Zhang Chuanjun Huang Yong Li Bingkun Lyu Fuzhi Shen Wentao Sun Laifeng Li | 2023 | Journal of Materials Science & Technology2023，，32： | 0 |
| 13 | In-situ monitored chemical bath deposition of planar NiO x layer for inverted perovskite solar cell with enhanced efficiency显示文摘As a convenient,low-cost and up-scalable solution route,chemical bath deposition(CBD)has exhibited impressive advantages in fabricating electron transporting materials like SnO_(2),achieving record efficien-cies for regular n-i-p perovskite solar cells(PSCs).However,for the hysteresis-free and potentially more stable inverted p-i-n PSCs,CBD processing is rarely studied to improve the device performance.In this work,we first present a CBD planar NiO x film as the efficient hole transport layer for the inverted per-ovskite solar cells(IPSCs).The morphologies and semiconducting properties of the NiO x film can be ad-justed by varying the concentration of[Ni(H 2 O)x(NH 3)6-x]2+cation via in-situ monitoring of the CBD re-action process.The characterizations of ultraviolet photoelectron spectroscopy,transient absorption spec-troscopy,time-resolved photoluminescence suggest that the CBD planar NiO x film possesses enhanced conductivity and aligned energy band levels with perovskite,which benefits for the charge transport in the IPSCs.The devices based on planar NiO x at 50°C and low nickel precursor concentration achieved an enhanced efficiency from 16.14%to 18.17%.This work established an efficient CBD route to fabricate planar NiO x film for PSCs and paved the way for high performance PSCs with CBD-prepared hole transporting materials. | Liqi Li Wenjian Shen Chenquan Yang Yuxi Dou Xuehao Zhu Yao Dong Juan Zhao Junyan Xiao Fuzhi Huang Yi-Bing Cheng Jie Zhong | 2023 | Journal of Materials Science & Technology2023，，2： | 0 |

| 15 | Aqueous Sn-S Complex Derived Electron Selective Layer for Perovskite Solar Cells显示文摘A novel aqueous Sn-S complex solution was applied as precursor to fabricate SnO2 electron selective layers (ESLs) for the hybrid perovskite solar cells (PSCs).The tin and sulfur powder were directly dissolved in a (NH4)2S water solution to form Sn-S precursor.After depositon and annealing,the SnO2 film was formed,presenting as a low cost and enviromental friendly method for preparation of ESL.The films showed excellent transmittance at visible wavelength range.Moreover,the method exhibited high compatibility for doping using Cu,Cd,Li,and Zn elements.Zn doping (0.05 M) in the as-prepared SnO2 ESL significantly improved perovskite solar cells (PSCs) performance.The highest PCE of 13.17% was achived with 15% enhancement compared to that of undoped SnO2 ESL samples.TiCl4 modifications on SnO2 film improved photovoltaic performance to 14.45%,but resulted in the poor long-term stability,around 80% more degredation than that of PSCs based on Zn-doped SnO2 films. | LI Zhi SHEN Wenjian ZHAO Juan YING Hangkai WU Zhengli LIU Yifan LI Wangnan KU Zhiliang PENG Yong HUANG Fuzhi CHENG Yibing ZHONG Jie FU Zhengyi | 2020 | Journal of Wuhan University of Technology(Materials Science)2020，35，2： | 0 |
| 16 | Low-cost biodegradable lead sequestration film for perovskite solar cells显示文摘Despite the high efficiency that has been achieved for the perovskite solar cells(PSCs),the hazardous lead leakage from the perovskite absorber layer is one of the crucial barriers still hindering its penetration into the commercial market for a large-scale installation.Herein,we report a novel low-cost and biodegradable lead sequestration layer with high compatibility for up-scalable encapsulation of PSCs.Through a precisely designed cross-linking reaction of chemical agents,the as-made biodegradable chitosan composite film shows enhanced mechanical strength,chemical stability,and lead adsorption capacity.The designed encapsulation strategy reduces over 99.99% lead leakage to <2 ppb under varied simulations of weather conditions(hail,rain,or flood),which meet the safe level of drinking water set by the US Environmental Protection Agency(EPA).Moreover,the PSC efficiency is improved from 21.91% to22.82% due to the improved light absorption from the printed biodegradable lead absorption film.Finally,we present a prototype process of accumulation and recycling of lead compounds in PSCs derbies via the biodegradation process.Based on the low-cost biodegradable lead sequestration film,this environmental-friendly encapsulation strategy could address the lead leakage issue for further commercialization of PSCs. | Yiming Xiong Haoyu Cai Wang Yue Wenjian Shen Xuehao Zhu Juan Zhao Fuzhi Huang Yi-Bing Cheng Jie Zhong | 2023 | Journal of Energy Chemistry2023，，9： | 0 |

| 18 | Nitrogen‐doped tin oxide electron transport layer for stable perovskite solar cells with efficiency over 23%显示文摘Tin oxide has made a major breakthrough in high-efficiency perovskite solar cells(PSCs)as an efficient electron transport layer by the low-temperature chemical bath deposition method.However,tin oxide often contains pernicious defects,resulting in unsatisfactory performance.Herein,we develop high-quality tin oxide films via a nitrogen-doping strategy for high-efficiency and stable planar PSCs.The aligned energy level at the interface of doped SnO_(2)/perovskite,more excellent charge extraction and reduced nonradiative recombination contribute to the enhanced efficiency and stability.Correspondingly,the power conversion efficiency of the devices based on N‐SnO_(2) film increases to 23.41% from 20.55% of the devices based on the pristine SnO_(2).The N-SnO_(2) devices show an outstanding stability retaining 97.8% of the initial efficiency after steady-state output at a maximum power point for 600s under standard AM1.5G continuous illumination without encapsulation,while less than 50% efficiency remains for the devices based on pristine SnO_(2).This simple scalable strategy has shown great promise toward highly efficient and stable PSCs. | Yanping Mo Chao Wang Xuntian Zheng Peng Zhou Jing Li Xinxin Yu Kaizhong Yang Xinyu Deng Hyesung Park Fuzhi Huang Yi‐Bing Cheng | 2022 | Interdisciplinary Materials2022，1，2： | 0 |
| 19 | Efficient flexible perovskite solar cells and modules using a stable SnO_(2)-nanocrystal isopropanol dispersion显示文摘The outstanding advantages of lightweight and flexibility enable flexible perovskite solar cells(PSCs)to have great application potential in mobile energy devices.Due to the low cost,low-temperature processibility,and high electron mobility,SnO_(2) nanocrystals have been widely employed as the electron transport layer in flexible PSCs.To prepare high-quality SnO_(2) layers,a monodispersed nanocrystal solution is normally used.However,the SnO_(2) nanocrystals can easily aggregate,especially after long periods of storage.Herein,we develop a green and cost-effective strategy for the synthesis of high-quality SnO_(2) nanocrystals at low temperatures by introducing small molecules of glycerol,obtaining a stable and well-dispersed SnO_(2)-nanocrystal isopropanol dispersion successfully.Due to the enhanced dispersity and super wettability of this alcohol-based SnO_(2)-nanocrystal solution,large-area smooth and dense SnO_(2) films are easily deposited on the plastic conductive substrate.Furthermore,this contributes to effective charge transfer and suppressed non-radiative recombination at the interface between the SnO_(2) and perovskite layers.As a result,a greatly enhanced power conversion efficiency(PCE)of 21.8%from 19.2%is achieved for small-area flexible PSCs.A large-area 5 cm×5 cm flexible perovskite solar mini-module with a champion PCE of 16.5%and good stability is also demonstrated via this glycerol-modified SnO_(2)-nanocrystal isopropanol dispersion approach. | Zhiwei Su Jing Li Ruixuan Jiang Shujie Zhang Chengkai Jin Feng Ye Bingcan Ke Mengjun Zhou Jinhui Tong Hyesung Park Fuzhi Huang Yi-Bing Cheng Tongle Bu | 2024 | Nano Research2024，17，4： | 0 |
| 20 | “Coffee ring” controlment in spray prepared >19% efficiency Cs_(0.19)FA_(0.81)PbI_(2.5)Br_(0.5) perovskite solar cells显示文摘Achieving high-quality perovskite films with uniform morphology and homogeneous crystallinity is challenging owing to the coffee ring effect(CRE) in the spray-coating technologies. In this study, an evaporation/spray-coating two-step deposition method is used to fabricate Cs_(0.19)FA_(0.81)PbI_(2.5)Br_(0.5)light harvesters for perovskite solar cells(PSCs). Considering the solid–liquid reaction, we establish a reaction-dependent regulating strategy that inhibits CRE successfully and prepare a high-quality perovskite layer, wherein the solvent for the FAI/Br solution during the spraying process is changed from isopropanol to n-butyl alcohol(NBA). The retarded-drying-enhanced spreading of the NBA solution inhibits contact line pinning to suppress the capillary flows and increases the reaction between metal halides(CsI/PbI_(2)) and organic salts(FAI/Br), which result in a reduction in the accumulation of solutes in the periphery effectively inhibiting CRE. Consequently, we obtain a high performance Cs_(0.19)FA_(0.81)PbI_(2.5)Br_(0.5) PSC with a power conversion efficiency(PCE) of 19.17%. An enlarged perovskite film(10 × 10 cm^(2)) containing 40 sub-cells is prepared. The average PCE of these devices is 18.33 ± 0.56%, proving the reliability of the 'coffee ring' regulating strategy. This study provides an effective approach for CRE controlment in spraying technology to achieve high repeatability devices with good performance. | Xinxin Yu Jing Li Yanping Mo Tianxing Xiang Zhiliang Ku Fuzhi Huang Fei Long Yong Peng Yi-Bing Cheng | 2022 | Journal of Energy Chemistry2022，31，4： | 0 |
