A self-assembled monolayer of 3-aminopropanoic acid （C3-SAM） was used on the surface of indium tin oxide （ITO） before depositing the CuI films. Consequently, a well-distributed and smooth CuI film was formed with pinhole free and complete surface coverage. The root mean square of the corresponding CuI film was reduced from 3.63 nm for ITO/CuI to 0.77 nm. As a result, the average power conversion efficiency （PCE） of PSCs with the device structure of ITO/C3-SAM/CuI/P3HT：PC61BM/ZnO/Al increased significantly from 2.55% （best 2.66%） to 3.04% （best 3.20%） after C3-SAM treatment. This work provides an effective strategy to control the morphology of CuI films through interracial modification and promotes its application in efficient PSCs.展开更多

The final R = 0.0418 and wR = 0.0936 for 1451 observed reflections with 1 〉 2σ（I） and R = 0.0422 and wR = 0.0939 for all data. In the complex, the Cu atoms are coordinated by one nitrogen atom and three iodine atoms to form a double-stranded stair, and such stairs are further linked to build a 2D framework via C-H…I interactions.展开更多
