Abstract

Ag nanoparticles were added to the inverted polymer solar cell based on narrow-band material PSBTBT: PC71BM heterojunction in this paper. After the addition of Ag nanoparticles into MoO3 HTL (Hole Transport Layer), the photoelectric conversion efficiency of the device was improved to 3.15%, with an increase of 41%. The active layer material devices with different mass ratios showed different performance, and the standard device with a mass ratio of 1:1 showed relatively better performance. The performance of the device with a mass ratio of 1:1.5 was improved after the addition of Ag nanoparticles.
