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
Multi-cation Synergy Suppresses Phase Segregation in Mixed-Halide Perovskites
Hoang X. Dang,Hoang X. Dang,Kai Wang,Masoud Ghasemi,Ming-Chun Tang,Michele De Bastiani,Erkan Aydin,Emilie Dauzon,Dounya Barrit,Jun Peng,Jun Peng,Detlef-M. Smilgies,Stefaan De Wolf,Aram Amassian,Aram Amassian +14 more
TL;DR: In this article, the authors track the solidification of precursors in situ and link the evolutions of different crystalline phases to the presence of Cs+ and Rb+ in mixed lead halide perovskite solar cells.
Journal ArticleDOI
π-Bridge-Independent 2-(Benzo[c][1,2,5]thiadiazol-4-ylmethylene)malononitrile-Substituted Nonfullerene Acceptors for Efficient Bulk Heterojunction Solar Cells
Kai Wang,Yuliar Firdaus,Maxime Babics,Federico Cruciani,Qasim Saleem,Abdulrahman El Labban,Maha A. Alamoudi,Tomasz Marszalek,Wojciech Pisula,Wojciech Pisula,Frédéric Laquai,Pierre M. Beaujuge +11 more
TL;DR: In this article, the authors show that 2-(benzo[c][1,2,5]thiadiazol-4-ylmethylene)malononitrile (BM)-terminated SM acceptors can achieve efficiencies as high as 5.3% in BHJ solar cells with the polymer donor PCE10.
Journal ArticleDOI
Kinetic Stabilization of the Sol-Gel State in Perovskites Enables Facile Processing of High-Efficiency Solar Cells.
