Rubidium Multication Perovskite with Optimized Bandgap for Perovskite-Silicon Tandem with over 26% Efficiency
Yiliang Wu,Heping Shen,Jun Peng,Xiao Fu,Daniel A. Jacobs,Er-Chien Wang,Teng Kho,Kean Chern Fong,Matthew Stocks,Evan Franklin,Andrew Blakers,Ngwe Zin,Keith R. McIntosh,Wei Li,Yi-Bing Cheng,Thomas P. White,Klaus Weber,Kylie R. Catchpole +17 more
TL;DR: Rubidium (Rb) is explored as an alternative cation to use in a novel multication method with the formamidinium/methylammonium/cesium (Cs) system to obtain 1.73 eV bangap perovskite cells with negligible hysteresis and steady state efficiency as high as 17.4 as discussed by the authors.
Journal ArticleDOI
Interface passivation using ultrathin polymer–fullerene films for high-efficiency perovskite solar cells with negligible hysteresis
Jun Peng,Yiliang Wu,Wang Ye,Daniel A. Jacobs,Heping Shen,Xiao Fu,Yimao Wan,Nandi Wu,Chog Barugkin,Hieu T. Nguyen,Dingyong Zhong,Juntao Li,Teng Lu,Yun Liu,Mark Lockrey,Klaus Weber,Kylie R. Catchpole,Thomas P. White,Thomas P. White +18 more
TL;DR: In this article, an ultrathin passivation layer consisting of a PMMA:PCBM mixture was proposed to suppress interfacial recombination at or near the perovskite/TiO2 interface.
Journal ArticleDOI
A Universal Double‐Side Passivation for High Open‐Circuit Voltage in Perovskite Solar Cells: Role of Carbonyl Groups in Poly(methyl methacrylate)
Jun Peng,Jafar Iqbal Khan,Wenzhu Liu,Esma Ugur,Yiliang Wu,Heping Shen,Kai Wang,Hoang X. Dang,Erkan Aydin,Xinbo Yang,Yimao Wan,Klaus Weber,Kylie R. Catchpole,Frédéric Laquai,Stefaan De Wolf,Thomas P. White +15 more
TL;DR: In this article, the perovskite cell devices were designed and analyzed with the support of the Australian Government through the Australian Renewable Energy Agency (ARENA) and the Australian Research Council.
Journal ArticleDOI
High-Performance TiO2 -Based Electron-Selective Contacts for Crystalline Silicon Solar Cells.
TL;DR: Thin TiO2 films are demonstrated to be an excellent electron-selective contact for crystalline silicon solar cells featuring a full-areaTiO2 -based electron- selective contact.
Journal ArticleDOI
