Gradually modulating the three parts of D-π-A type polymers for high-performance organic solar cells

By gradually modulating electron-donating (D), π-bridge and electron-accepting (A) units, we systematically investigated the effect on photovoltaic performances of D-π-A type conjugated polymers and realized the highest power conversion efficiency of 14.4%. [Display omitted]
