Abstract

We demonstrate a brushing technique as a promising method for the mass production of efficient and flexible solar cells even on a non-flat surface such as roofing tiles. Higher device efficiency could be obtained compared to the spin-coated devices, resulting from the improved organization of polymer chains and domains induced by more effective application of shear stress to the polymer chains during the brushing process.
