In this work, we report perovskite solar cells in the planar p–i–n configuration based on single-step, anti-solvent-free, low-temperature (70 °C) slot-die-coated methylammonium lead tri-iodide (MAPbI₃). The devices are fabricated on hydrophobic poly(triarylamine) (PTAA) surfaces, using key strategies such as solvent engineering, enhanced ink–substrate dynamics, and surface passivation, enabling a power conversion efficiency (PCE) of 21.8%. We also adapted the technique to achieve the first slot-die-coated perovskite/silicon monolithic 2-terminal tandems, achieving a PCE of 23.8% utilizing a textured silicon bottom cell.

高性能钙钛矿单结和通过槽模涂覆的纹理钙钛矿/硅串联太阳能电池

在这项工作中，我们报告了基于单步，无溶剂，低温（70°C）狭缝模头涂覆的三碘化甲基铵铅（MAPbI）的平面pn结构的钙钛矿太阳能电池₃）。该设备使用诸如溶剂工程，增强的油墨-基材动力学和表面钝化等关键策略在疏水性聚三芳基胺（PTAA）表面上制造，从而实现21.8％的功率转换效率（PCE）。我们还对技术进行了调整，以实现第一个缝模涂覆的钙钛矿/硅单片2端双极膜，利用带纹理的硅底部电池实现了23.8％的PCE。
