Claim 11:
12. A method for preparing a perovskite solar cell, the method comprising a step of preparing a hole transport layer, a step of preparing a perovskite layer, a step of preparing an electron transport layer, and a step of preparing a back electrode, wherein a passivation layer is disposed between the hole transport layer and the perovskite layer, and preparation of the passivation layer comprises the following steps:
step S1: preparing or making a passivation material ready, the passivation material comprising an amide and/or a cation thereof, wherein the amide comprises a compound of formula (1) and/or formula (2):, wherein
R1 and R2 are each independently selected from hydrogen, —R, —NR2, —NH2, —OH, —OR, —-NHCOR, —OCOR, and —CH2COOH, wherein 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, wherein Ar is selected from a C5-C10 aryl or heteroaryl group;
step S2: formulating a solution of the passivation material; and
step S3: coating the solution of the passivation material on the perovskite layer, and then performing annealing to obtain the passivation layer.
