WebSep 12, 2024 · Abstract. Inorganic perovskite CsPbI 3 has exhibited promising performance in single-junction solar cells, but the grain boundaries (GBs) in its film cause the formation of the defects with deep energy levels (such as iodide vacancy ( VI )) and impede the transport of carriers, worsening the efficiency and stability of the solar cells. WebApr 26, 2024 · It is found that for CsI-rich growth conditions, CsPbI 3 can be synthesized directly at low temperature into the distorted perovskite γ-CsPbI 3 phase without detectable secondary phases. In contrast, PbI 2 -rich growth conditions are found to lead to the non-perovskite δ-phase. WebHerein, we modulated the nucleation and growth rate of CsPbI 3 crystals by using a Mo doping strategy to synthesize high-quality SnO 2 crystals as an ETL nano-film in n–i–p heterojunction perovskite solar cells.
