The efficiency of perovskite/silicon tandem solar cells has exceeded the previous record for III-V-based dual-junction solar cells. This shows the high potential of perovskite solar cells in multi-junction applications. Perovskite/perovskite/silicon triple-junction solar cells are now the next step to achieve efficient and low-cost multi-junction solar cells with an efficiency potential even higher than that for dual-junction solar cells. Here we present a perovskite/perovskite/silicon triple-junction solar cell with an open circuit voltage of >2.8 V, which is the record value reported for this structure so far. This is achieved through employing a gas quenching method for deposition of the top perovskite layer as well as optimization of interlayers between perovskite subcells. Moreover, for the measurement of our triple-junction solar cells, precise measurement procedures are implemented to ensure the reliability and accuracy of the reported values.
钙钛矿/硅串联太阳能电池的效率已超过此前基于III-V族的双结太阳能电池的记录。这显示出钙钛矿太阳能电池在多结应用中的巨大潜力。钙钛矿/钙钛矿/硅三结太阳能电池是实现高效且低成本多结太阳能电池的下一步，其效率潜力甚至高于双结太阳能电池。在此，我们展示了一种开路电压大于2.8 V的钙钛矿/钙钛矿/硅三结太阳能电池，这是迄今为止该结构所报道的记录值。这是通过采用气体猝灭法沉积顶部钙钛矿层以及优化钙钛矿子电池之间的中间层来实现的。此外，对于我们的三结太阳能电池的测量，实施了精确的测量程序以确保所报道值的可靠性和准确性。
