Abstract

We fabricated the inverted polymer solar cells (PSCs) with a structure of ITO/ZnO/PTB7:PC₇₁BM/MoO₃/Ag, and investigate the influence of spin coating on the device performance in this article. Through modifying the spin coating parameters, the high PSC performance could be obtained with V_OC=0.769 (V), J_SC=11.6 (mA/cm²), FF=58.8 % and PCE=5.26 %, respectively. The improvement of device performance was attributed to the enhanced absorption of active layer in the wavelength from 550 nm to 700 nm and the increased phase separation of PTB7:PC₇₁BM.
