Cation optimization for burn-in loss-free perovskite solar devices

Mohammad Khaja Nazeeruddin, Sanghyun Paek, Cristina Roldán Carmona, Marius Franckevicius, Olga Syzgantseva

Hybrid lead halide perovskites will potentially lead the future energy scenario if highly efficient cells have long-term stability. Here we combine state-of-the art mixed-cation formulations containing formamidinium (FA) and methylammonium (MA), with optim ...

Cut from the Same Cloth: Enamine-Derived Spirobifluorenes as Hole Transporters for Perovskite Solar Cells

Mohammad Khaja Nazeeruddin, Paul Joseph Dyson, Bin Ding, Kasparas Rakstys, Albertus Adrian Sutanto, Cansu Igci

To attain commercial viability, perovskite solar cells (PSCs) have to be reasonably priced, highly efficient, and stable for a long period of time. Although a new record of a certified power conversion efficiency (PCE) value over 25% was achieved, PSC perf ...
