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.
