Understanding the Degradation Factors, Mechanism and Initiatives for Highly Efficient Perovskite Solar Cells

“…ITO/NiO x /CsPbI 2 Br/Ti 0.9 Sn 0.1 O 2 /Ag PSC structure was synthesized by doping Sn into the electron transport layer and obtained an efficiency of 14%. The unencapsulated device retained 98% efficiency at 85 °C for 1560 hours aging [95] . The research group of A Jamshaid et al., [107] have observed MAPbI 3 as a thermodynamically and kinetically stable after incorporation of certain amount (below 18.75%) of Cl ions.…”

The progress and efficiency of CsPbI2Br perovskite solar cells

“…187,188 Recently, solution-processed Sn-doped TiO 2 (Ti 1− x Sn x O 2 ) NCs were prepared as the ETL in inverted CsPbI 2 Br IPSCs, which showed higher conductivity compared to TiO 2 . 189 Moreover, the Sn-doped TiO 2 films improved the interface contact in the IPSCs owing to the facile film formation, high electron mobility, and suitable energy level, leading to PCEs of 14% for small-sized devices and 11.2% for 1.0 cm 2 devices, respectively. Additionally, the Sn-doped TiO 2 NCs showed high light stability and heat resistance, which enhanced the light and thermal stability of the CsPbI 2 Br IPSCs.…”

Effects of Adding Alkali Metals and Organic Cations to Cu-Based Perovskite Solar Cells

“…There have been many efforts to improve the conversion efficiencies and durabilities of perovskite photovoltaic devices by adding metal, halogen, and organic ions to the precursor solutions [1][2][3]. Other approaches have included the development of scalable processes via electrodeposition [4,5], stable fully inorganic perovskites [6], polymer composites using perovskites [7], and solvent effects in the precursor solution on perovskite film microstructures [8].…”
