Numerical simulation and optimization of all-inorganic Ca3PI3/CsSnI3 heterojunction perovskite solar cells
To date, inorganic lead-free perovskite solar cells (PSCs) have lagged behind their lead-based and organic–inorganic hybrid counterparts in power conversion efficiency (PCE). To address this challenge, specially avoiding lead toxicity and reducing fabrication costs, we propose a fully inorganic, hole-transport-layer-fr...
