Perovskite solar cells (PSC) offer a promising solution for building integrated photovoltaics (BIPVs) due to its high photoelectric conversion efficiency (PCE). However, increasing the transparency of their functional layers dramatically decreases the PCE. Here, a computer controlled laser patterning method was proposed to directly turn PSC modules into semitransparent and with aesthetic artificial pattern, without additional complexities to the conventional PSCs fabrication process. A structured ST-PSC achieving a champion PCE of 17.5% with average visible transparency (AVT) of 18.2%, and a mini-module with 5 × 5 cm delivering a PCE of 9.1% with AVT of 37.7% were demonstrated. Rationally designed aesthetic patterns were imprinted on mini-modules, achieving a PCE of 14.4%. These results reveal a new route for low-cost facile fabricating high performance large-area aesthetic BIPV modules, and represent a big step forward toward the fabrication of solar cells with high efficiency and high transparency.
由于其高光电转换效率（PCE），钙钛矿太阳能电池（PSC）为建筑一体化光伏（BIPV）提供了一个有前景的解决方案。然而，提高其功能层的透明度会显著降低PCE。在此，提出了一种计算机控制的激光图案化方法，可直接将PSC模块转变为半透明且具有美观人工图案的模块，而不会给传统PSC制造工艺带来额外复杂性。展示了一种结构化的ST-PSC，其冠军PCE为17.5%，平均可见光透明度（AVT）为18.2%，以及一个5×5厘米的微型模块，其PCE为9.1%，AVT为37.7%。在微型模块上印上了合理设计的美观图案，实现了14.4%的PCE。这些结果揭示了一条低成本简便制造高性能大面积美观BIPV模块的新途径，并代表着向制造具有高效率和高透明度的太阳能电池迈出了一大步。
