A new hole-transporting material (XJ-05) based on a 9,9'-bicarbazole core and four acetylene-linked triphenylamine groups was designed and applied for perovskite solar cells (PSCs). Optical spectra, thermal stability, electrochemical properties, density fu ...
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 ...
The power conversion efficiency of perovskite solar cells is approaching the Shockley-Queisser limit, and therefore this technology is next to the commercialization stage. Inexpensive and stable hole transporting materials are highly desirable for the succ ...
Development of sustainable energy sources is among the most urgent needs of modern society. Solar energy technologies, and in particular, hybrid perovskite solar cells (HPSCs), have demonstrated hard-to-beat performances with large capacities for improveme ...
