We are pleased to present this special issue on Advances in Solar Energy: Special Issue on Perovskite Solar Cells, which covers invited reviews and research articles on the perovskite materials and devices. Prof. Miyasaki first invented perovskite solar cells with a device efficiency of 3.8 %, and swiftly crossed to over 26 % in a single junction device. In silicon/perovskite tandem, solar cells the efficiency reached over 34 %. The device efficiency reached by 40 % under low-light/ artificial indoor light

The purpose of this article is twofold. On the one hand the method of spacial resolved photoemission spectroscopy on small angle tapered cross-sections (TCS) of complete devices is introduced to analyze simultaneously the chemical and electronic structure. ...

Metal halide perovskite field‐effect transistors (PeFETs) have rapidly gained recognition as leading candidates for next‐generation electronic and optoelectronic technologies, owing to their exceptional optoelectronic properties, facile solution processability, and notable mechanical flexibility. Nevertheless, the practical deployment of high‐performance PeFETs is significantly impeded by persistent challenges, including ion migration, hysteresis effects, and environmental instability, which collectively hi

Iron and nitrogen co‐doped FeNC catalysts with symmetric Fe‐N 4 as the active site are the most promising alternative to noble metal catalysts for proton exchange membrane fuel cells (PEMFCs). However, the symmetric structure in the Fe–N 4 site endows oxygen intermediates with strong binding energy, which hinders the activity optimization of the active center. In this work, an asymmetric configuration (Fe‐N 3 SC) is constructed to alleviate the electron localization caused by the d – π conjugation of Fe‐N 4
