b, FTIR peaks of HBzA, 2PACz, and mixture (2PACz:HBzA, 1:1 molar ratio) in solid-state powder. The shifting peaks of P–OH at ~950 cm−1 and ~1033 cm−1 to the higher wavenumber of the mixture compound indicate stronger bonding due to deprotonation of the first P–OH group ...
All-inorganic perovskites prepared by substituting the organic cations (for example, methylammonium and formamidinium) with inorganic cations (for example, Cs+) are effective concepts to enhance the long-term photostability and thermal stability of perovskite solar cells (PSCs)1,2. Hence, inorganic ...
