Acrylate and methacrylate derivatives of fullerenes as electron-selective buffer layer materials for inverted organic solar cells

Inverted organic solar cells were designed using the acrylic and methacrylic derivatives of C₆₀ as buffer layer materials. The highest power conversion efficiency was reached for solar cells comprising the methacrylic derivative {(1-methoxycarbonyl-1-[2-(methacryloyloxy)ethoxycarbonyl]-1,2-methane)}-1,2-dihydro-C₆₀-fullerene.
