| 1 | Ion–Electron Coupling Enables Ionic Thermoelectric Material with New Operation Mode and High Energy Density显示文摘Ionic thermoelectrics(i-TE) possesses great potential in powering distributed electronics because it can generate thermopower up to tens of millivolts per Kelvin. However,as ions cannot enter external circuit, the utilization of i-TE is currently based on capacitive charge/discharge, which results in discontinuous working mode and low energy density. Here,we introduce an ion–electron thermoelectric synergistic(IETS)effect by utilizing an ion–electron conductor. Electrons/holes can drift under the electric field generated by thermodiffusion of ions, thus converting the ionic current into electrical current that can pass through the external circuit. Due to the IETS effect, i-TE is able to operate continuously for over 3000 min.Moreover, our i-TE exhibits a thermopower of 32.7 mV K^(-1) and an energy density of 553.9 J m^(-2), which is more than 6.9 times of the highest reported value. Consequently, direct powering of electronics is achieved with i-TE. This work provides a novel strategy for the design of high-performance i-TE materials. | Yongjie He Shaowei Li Rui Chen Xu Liu George Omololu Odunmbaku Wei Fang Xiaoxue Lin Zeping Ou Qianzhi Gou Jiacheng Wang Nabonswende Aida Nadege Ouedraogo Jing Li Meng Li Chen Li Yujie Zheng Shanshan Chen Yongli Zhou Kuan Sun | 2023 | Nano-Micro Letters2023，15，7： | 1 |
| 2 | Annealing-free alcohol-processable MoO_(X) anode interlayer enables efficient light utilization in organic photovoltaics显示文摘Molybdenum oxide(MoO_(x))is a commonly used hole extraction material in organic photovoltaics.The MoO_(x) interlayer is deposited typically via thermal evaporation in vacuum.To meet the need for rollto-roll manufacturing,solution processing of MoO_(x) without post-annealing treatment is essential.Herein,we demonstrate an effective approach to produce annealing-free,alcohol-processable MoO_(x) anode interlayers,namely S-MoO_(x),by utilizing the bis(catecholato)diboron(B_(2) Cat_(2))molecule to modify the surface oxygen sites in MoO_(x).The formation of surface diboron-oxygen complex enables the alcohol solubility of S-MoO_(x).An enhanced light utilization is realized in the S-MoO_(x)-based organic photovoltaics.This affords a superior short-circuit current density(Jsc)close to 26 mA cm^(-2) and ultimately a high power-conversion efficiency(PCE)of 15.2%in the representative PM6:Y6 based inverted OPVs,which is one of the highest values in the inverted OPVs using an as-cast S-MoO_(x) anode interlayer. | Ke Yang Shanshan Chen Yongli Zhou George Omololu Odunmbaku Zhenghong Xiong Qianguang Yang Ming Wang Zhipeng Kan Zeyun Xiao Shirong Lu Kuan Sun | 2021 | Journal of Energy Chemistry2021，30，10： | 0 |
