Abstract The advancement in a power conversion efficiency (PCE) to reach 25%, the inorganic perovskites are being
explored intensively as promising optoelectronic materials due to their excellent photovoltaic performance, i.e.,
thermal stability and efficiency. Lately, the inorganic cesium lead halide perovskite is studied to show enhanced
light absorption, however, it suffers from the phase separate into I-rich and Br-rich phase which leads to poor film
quality due to difference of electronegativity. Herein, we propose a unique solution of controlling the rate of solvent volatilization followed by gel method to inhibit phase separation effectively to obtain the homogenous and
pinhole-free CsPbIBr2 films… More >
