| 1 | 19.34 cm2 large-area quaternary organic photovoltaic module with 12.36% certified efficiency显示文摘In this study, a quaternary blending strategy was applied in the fabrication of organic photovoltaic devices and large-area modules. As a result, the ultimate quaternary organic solar cells(OSCs) deliver 16.71% efficiency for small-area devices and 13.25% for large-area(19.34 cm2) modules(certified as 12.36%), which is one of the highest efficiencies for organic solar modules to date. Our results have proved the synergistic effects of multiple components in OSCs, providing an effective strategy for achieving high-performance organic photovoltaic devices and modules. | Ziyan Jia Zeng Chen Xu Chen Jizhong Yao Buyi Yan Rui Sheng Haiming Zhu Yang(Michael)Yang | 2021 | Photonics Research2021，9，3： | 2 |
| 2 | A multifunctional and scalable fullerene electron transporting material for efficient inverted perovskite solar cells and modules显示文摘The interfacial properties between charge transporting material and perovskite(PVSK)play critical roles in governing the photovoltaic performances of perovskite solar cells(PVSCs).Herein,we develop a multifunctional fulleropyrrolidine(FMG)as an electron transporting material(ETM),which facilitates the construction of efficient and stable inverted PVSCs and modules.It revealed that the facile and scalable FMG possesses not only excellent electron extraction capabilities,but also multi-groups to simultaneously passivate PVSKs via Lewis acid-base and hydrogen bonding interactions.The coating of FMG onto PVSK interestingly yields a dense and interactive layer with the graded ETM-PVSK heterojunction architecture.As a result,FMGbased PVSCs demonstrate a champion efficiency of 23.8%,outperforming 21.0%of PCBM-based devices.FMG could also be utilized to improve photovoltaic performance of large-scale modules.In addition,FMG has successfully elongated the lifetime of the corresponding PVSCs,maintaining 85%of the initial performance after the continuous 60-day one sun equivalent illumination in ambient. | Kangrong Yan Ziqiu Shen Benfang Niu Yanchun Huang Di Wang Emely Gu Buyi Yan Jizhong Yao Hongzheng Chen Chang-Zhi Li | 2023 | Science China Chemistry2023，66，6： | 0 |
