Original Abstract Submitted
The invention develops a novel hole-transporting material (HTM), PTAA-P1 and PTAA-P2 via the backbone engineering strategy to modulate wettability and promote anchoring. The HTM properties can be effectively modified by varying the linkage sites of incorporated pyridine units. The 3,5-linked PTAA-P1 particularly demonstrates a more regulated molecular configuration for interacting with perovskites, forming a highly crystalline perovskite film with uniform back contact and reduced defect density. The invention also develops the perovskite solar cell including the novel HTM with remarkable PCE efficiency and stability for small-area and large-area solar cells. The invention also develops the method for fabricating the perovskite solar cell.
