Anode Modification

The organic solar cells with a structure of ITO/Rubrene(35 nm)/C60(35 nm)/BCP (6 nm)/Al(150 nm) was fabricated and the influence of anode modifying layer(MoO3) and 3V bias voltage treatment on device performance were investigated. The experiment results show, inserting anode modifying layer, the open-circuit voltage and the power conversion efficiency were almost increased by a factor of 5.3 and 11.3, respectively. The anode modifying layer can effectively enhance the built-in electric field and improve dissociation and transport excitons. The bias voltage treatment can improve the performance of defective devices by burning partial defects, but there is little effect for too few defective devices.
