Efficient Polymer Solar Cells Fabricated by Simple Brush Painting

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 polyme...

Description
Summary: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.
