Performance evaluation of all-inorganic cesium-based perovskite solar cell with BaSnO3 as ETL

The organic HTL in highly efficient germanium-alloyed CsSnI3 perovskite solar cell: a modelling and computational analysis

“…Similarly, Bhattarai et al (2023) used double active perovskite layers consisting of MASnI 3 and CsSnGeI 3 , which revealed a PCE of 31.53% [31]. Additionally, Tara et al (2023) achieved a PCE of 28.21% in CsSn 0.5 Ge 0.5 I 3 -based PSC using spiro-OMeTAD as HTL and BaSnO 3 as ETL [32]. However, most of the studies using CsSn 0.5 Ge 0.5 I 3 as the absorbent layer basically employ inorganic hole transport layers.…”
