Abstract
A tandem solar cell comprises a front subcell; a back subcell; and an interconnecting layer of Cr/MoObetween the front subcell and the back subcell and connecting the two subcells in series. The back subcell may be an isoindigo-based polymer. The front subcell may comprise a carbazole-thienyl-benzothiadiazole based polymer. The front subcell may comprise an isoindigo-based polymer. The isoindigo-based polymer is a repeating 2-thiophene-terminated polymer. A tandem solar cell comprises a substrate layer; a layer of PCDTBT:PCBM applied on the substrate layer; a bilayer of chromium and MoOapplied to the PCDTBT:PCBM layer; a layer of P(T3-il)-2:PCBM applied on the bilayer of chromium and MoO; and Ca and Al electrode layer on the top.
