Tandem solar cells constructed from a crystalline silicon (c-Si) bottom cell and a low-cost top cell offer a promising path to ensure long-term price reductions of solar modules. We present a four-terminal tandem consisting of a methyl ammonium lead triiodide (CH3NH3PbI3) top cell and a c-Si heterojunction bottom cell. The four-terminal tandem yields an efficiency of 13.4 % (top cell: 6.2 %, bottom cell: 7.2 %), which is a gain of 1.8%abs with respect to the reference single-junction CH3NH3PbI3 solar cell with metal back contact. We employ the four-terminal tandem for a detailed investigation of the optical losses and derive guidelines for further efficiency improvements. Based on a power loss analysis, we estimate that tandem efficiencies of ~28% are attainable with an optically optimized system based on current technology, whereas a fully optimized, ultimate device with matched current could lead up to 31.6%.
