Abstract

Here, the surface modification of RF sputtering NiOx films by 4PADCB (NiOx-P) is proposed for the first time. The modification effectively suppresses voltage loss at the hole transport layer (HTL)/perovskite interface and optimizes the energy band alignment between the perovskite layer and RF NiOx, thereby enhancing charge extraction and reducing nonradiative recombination of tandem devices, resulting in a flexible monolithic Perovskite (PVK)-CIGS tandem solar cell with the highest efficiency of 22.8% and an extremely high Open-circuit voltage (V_OC) of 1.82 V. This method is expected to obtain better flexible monolithic PVK-CIGS tandem solar cells.

聚合物衬底上VOC超过1.8 V的高效柔性单片钙钛矿- cigs串联太阳能电池

本文首次提出了用4PADCB （NiOx- p）对射频溅射NiOx薄膜进行表面改性的方法。该修饰有效抑制了空穴输运层(HTL)/钙钛矿界面处的电压损失，优化了钙钛矿层与RF NiOx之间的能带排列，从而增强了电荷提取，减少了串联器件的非辐射复合，从而获得了具有最高效率22.8%和极高开路电压（VOC） 1.82 V的柔性单片钙钛矿(PVK)-CIGS串联太阳能电池。该方法有望获得更好的柔性单片PVK-CIGS串联太阳能电池。
