Abstract
A tandem solar cell comprises a back subcell; a front subcell; and an interconnecting layer of Cr/MoO3 between the back subcell and the front subcell and connecting the two subcells in series. The front subcell may comprise a carbazole-thienyl-benzothiadiazole based polymer and the back subcell may comprise an isoindigo-based polymer. A method for making a tandem solar cell comprises a) providing a substrate layer; b) applying a layer of PCDTBT:PCBM to the substrate layer; c) applying a bilayer of chromium and MoOto the PCDTBT:PCBM layer; d) applying a layer of P(T3-iI)-2:PCBM on the bilayer of chromium and MoO; and e) applying a Ca and Al electrode layer on the top.
