文摘
Lead-free perovskite solar cells (PSCs) are very much in demand for future high-efficiency renewable electricity generation. In article number 1601130, Yuanyuan Zhou, Nitin P. Padture, Xiao Wei Sun, and co-workers report efficient planar heterojunction-depleted PSCs with power conversion efficiency up to 3.31% without the use of any additives, via modulation of phase-pure B-γ-CsSnI3 grain coarsening. The delicate control of grain-coarsening engineering plays a critical role in determining the morphology of photoactive layer, the exciton dynamical behaviors and thus the device performance.
