Improving the performance of solution-processed organic solar cells by incorporating small molecule acceptors into a ternary bulk heterojunction based on DH6T:Mq3:PCBM (M = Ga, Al)
Ternary solution-processed OSCs including Gaq3 and Alq3 acceptors were realized. The power and efficiency of the devices were increased by an order of 5.8. Broadened absorption and improved crystallinity were achieved for the active layers.
