Abstract High-efficiency perovskite solar cells (PSCs) have experienced rapid development and attracted significant attention in recent years. The PSCs based on doctor bladed or slot-die coated perovskite films usually have lower power conversion efficiency (PCE) than that based on spin-coated perovskite films. In this work, we have developed an effective method, called glass rod-sliding and low pressure assisted solution processing composition engineering (GRS-LPASP), to manufacture high quality perovskite film in air. GRS-LPASP composition engineering effectively increases the grain size and thickness of perovskite films and reduces the defect density by increasing the contact area between the perovskite layer and the hole transport layer, thus leading an increased current density (Jsc) of perovskite solar cells. The device with GRS-LPASP composition engineering achieves a maximum PCE of 19.78%. The experimental results demonstrates that GRS-LPASP composition engineering is a feasible method to prepare high-efficiency PSCs. Moreover, GRS-LPASP composition engineering also provides a potential approach for the commercial production of PSCs.

用于高效钙钛矿太阳能电池的玻璃棒滑动和低压辅助溶液加工组合工程

摘要 高效钙钛矿太阳能电池（PSCs）近年来发展迅速，受到广泛关注。基于刮刀或槽模涂层钙钛矿薄膜的 PSC 通常比基于旋涂钙钛矿薄膜的 PSC 具有更低的功率转换效率 (PCE)。在这项工作中，我们开发了一种有效的方法，称为玻璃棒滑动和低压辅助溶液加工组合工程 (GRS-LPASP)，可以在空气中制造高质量的钙钛矿薄膜。GRS-LPASP成分工程通过增加钙钛矿层与空穴传输层之间的接触面积，有效地增加了钙钛矿薄膜的晶粒尺寸和厚度，并降低了缺陷密度，从而提高了钙钛矿太阳能电池的电流密度（Jsc）。具有 GRS-LPASP 组合工程的设备实现了 19.78% 的最大 PCE。实验结果表明，GRS-LPASP 组合工程是制备高效 PSC 的可行方法。此外，GRS-LPASP 组合工程还为 PSC 的商业生产提供了一种潜在的方法。
