摘要： The present application provides a perovskite solar cell, including conductive glass, a hole transport layer, a perovskite layer, an electron transport layer and a back electrode, where a passivation layer may be disposed between the hole transport layer and the perovskite layer, and the passivation layer may include an amide and/or a cation thereof, where the amide may include a compound of formula (1) and/or formula (2):
where
R1 and R2 are each independently selected from hydrogen, —R, —NR2, —NHR, —NH2, —OH, —OR, —NHCOR, —OCOR, and —CH2COOH, where R represents a straight or branched chain alkyl group having 1-10 carbon atoms, m is an integer of 0 to 10; and n is an integer of 1 to 10; and
where Ar is selected from a C5-C10 aryl or heteroaryl group.
