The Relationship

In this review, small-molecule donors for application in organic solar cells reported in the last three years are highlighted. Especially, the effect of donor molecular structure on power conversion efficiency of organic solar cells is reported in detail. Furthermore, the mechanism is proposed and discussed for explaining the relationship between structure and power conversion efficiency. These results and discussions draw some rules for rational donor molecular design, which is very important for further improving the power conversion efficiency of organic solar cells based on the small-molecule donor.

Conversion Efficiencies

Recent efforts in research and development of small molecule based organic solar cells have led to power conversion efficiencies exceeding 10%. Understanding the incorporated interfaces in these devices is an utterly important parameter for their improvement. Here we investigate the influence ofα-sexithiophene (α-6T) nanostructures on the performance parameters ofα-6T/C60inverted bilayer solar cells. Byin situcontrolled growth, crystallineα-6T nanostructures are formed in the devices and a correlation between the morphology of the structures and the device performance is presented. Under certain, well-defined circumstances, we observe an efficiency increase of around 100% when implementing crystalline nanostructures.
