Latest research in the field of hybrid photovoltaics focuses on the benefits of inorganic and organic materials. Flexibility, low cost, and large-scale production are the most valuable properties of organic components whereas the inorganic components add chemical and physical stability. In this work, we analyze thin films with optical, electrical and morphological measurement techniques to understand and control the corresponding properties. An amphiphilic diblock copolymer templating with polystyrene-b-polyethylene oxide (PS-b-PEO) and a potassium-semiconductor-semiconductor precursor is used to prepare porous thin films via sol-gel synthesis. The focus is to implement these mesoporous nanostructures into hybrid photovoltaics.
