Design of Highly Efficient Semitransparent Perovskite/Organic Tandem Solar Cells

Solar cells transparent in the visible range are highly requested for integration see-through photovoltaic (PV) applications such as building glass façades or greenhouse roofs. The development of advanced PV can fully exploit tandem technology where top cell absorbs near-ultraviolet solar spectrum while bottom one near-infrared part. Herein, a possible implementation this paradigm, namely, structure composed high-bandgap halide perovskite and low-bandgap organic cell, is considered. Electro-optical simulation results based on parameters calibrated experimental data show that an efficiency 15% be achieved with average transmittance above 50%. This obtained considering mixed chlorine bromine anions, nonfullerene-based bulk heterojunction, well-calibrated light management, three-terminal configuration tandem.
