Monolithic Perovskite–Perovskite–Organic Triple-Junction Solar Cells with a Voltage Output Exceeding 3 V

Abstract: Monolithic integration of perovskite−perovskite−organic subcells yields a triple-junction solar cell with a record opencircuit voltage of 3.03 V and a power conversion efficiency of 19.4%. The proposed triple-junction architecture represents a milestone toward scalable photovoltaics, targeting efficiencies beyond the limit of single-junction devices.

“…The SHJ bottom cell in this work has a V OC of ∼0.73 V. Therefore, there is negligible voltage loss in the final triple-junction devices, which shows the high quality of the recombination layers between the subcells. We note that higher V OC values have been reported for triple-junction solar cells using a perovskite or organic bottom cell. , However, a voltage difference is expected between the technologies, as the silicon solar cell has a lower voltage compared to the other two bottom cells with bandgaps of 1.2 and 1.3 eV for perovskite and organic solar cells, respectively. , …”

“…162 The perovskite/perovskite/organic triple-junction solar cell also employed only 2 nm IZO as the recombination layer between perovskite middle cell and top cell. 16 Palmstrom et al attempted to produce recombination layer-free all-perovskite dual-junction solar cells. However, based on their results at least 5-15 nm of IZO is needed to achieve high FF.…”
