Approach to a block polymer precursor from poly(3-hexylthiophene) nitroxide-mediated in situ polymerization for stabilization of poly(3-hexylthiophene)/ZnO hybrid solar cells

► Cross-linked poly(3-hexylthiophene)-b-poly(zinc dimethacrylate) was synthesized. ► Stable poly(3-hexylthiophene)/ZnO hybrid solar cells were fabricated. ► This strategy integrates the advantages of in-situ and cross-linking. ► The approach shows promise in producing stable inverted hybrid solar cells.
