WebFeb 1, 2024 · Although the current ZT value of CsSnI 3 is still low, its thermoelectric potential can be further explored because its electrical conductivity is related to its intrinsic Sn defects, which offer a way to regulate the electrical conductivity of the perovskite semiconductor. WebJan 13, 2024 · Fully inorganic black orthorhombic (B-γ) CsSnI 3 has become a promising candidate for perovskite solar cell (PSC) thanks to its low toxicity and decently high theoretical power conversion efficiency (PCE). However, so far, the reported PCE of the B-γ CsSnI 3 PSC is still not comparable with its lead-based or organotin-based counterparts. …

WebCurrently, the exploration of green tin halide perovskite solar cells (PSCs) based on orthorhombic (γ-) CsSnI3 is fundamentally hindered by its intrinsic bad stability. Herein, based on the first principles calculation, three surface-ligand-passivated configurations having inter-molecular hydrogen bonds are WebNov 7, 2014 · Here we demonstrate rigorously that B-γ-CsSnI3 is not energetically possible to collect photogenerated holes because of the large energy barrier at the interface of N719/B-γ-CsSnI3. Therefore, it cannot serve as a hole-transporter for the conventional DSSCs although it is a good hole-conducting material. A solution-based method was …
