Crystalline silicon (c-Si) solar cells featuring a high-temperature processed homojunction have dominated the photovoltaic industry for decades, with a global market share of around 93%. Integrating commercially available crystalline silicon solar cells with high-efficiency perovskite solar cells is a viable pathway to increase the power conversion efficiency, and hence achieve low levelized electricity costs for the photovoltaic systems. However, the fabrication process for this type of cell is challenging due to the many, and often conflicting, material processing requirements and limitations. Here, we present an innovative design for a monolithic perovskite/silicon tandem solar cell, featuring a mesoscopic perovskite top subcell and a high-temperature tolerant homojunction c-Si bottom subcell. The improved temperature tolerance of the c-Si bottom cell permits significantly increased flexibility in the design and fabrication of the perovskite cell. We demonstrate an efficiency of 22.5% (steady-state) and a V_oc of 1.75 V on a 1 cm² cell. The method developed in this work opens up new possibilities in designing, fabricating and commercialising low-cost high-efficiency perovskite/c-Si tandem solar cells.

整体钙钛矿/硅均质串联太阳能电池，效率超过22％

数十年来，具有高温处理的同质结的晶体硅（c-Si）太阳能电池在光伏行业占据主导地位，其全球市场份额约为93％。将可商购获得的晶体硅太阳能电池与高效钙钛矿太阳能电池集成在一起是提高功率转换效率并因此实现光伏系统低水平电费的可行途径。然而，由于许多且通常是相互矛盾的材料处理要求和限制，用于这种类型的电池的制造工艺具有挑战性。在这里，我们提出了一种整体式钙钛矿/硅串联太阳能电池的创新设计，其特征在于介观钙钛矿顶部子电池和耐高温同质结c-Si底部子电池。c-Si底部电池的改进的温度耐受性允许钙钛矿电池的设计和制造中显着增加的灵活性。我们证明了22.5％（稳态）的效率和1 cm ²电池上的V _oc为1.75V 。这项工作中开发的方法为低成本，高效率的钙钛矿/ c-Si串联太阳能电池的设计，制造和商业化开辟了新的可能性。
