Nano-structured CuO-Cu2O complex thin film-based perovskite solar cells were fabricated on an indium tin oxide (ITO)-coated glass and studied. Copper (Cu) thin films with a purity of 99.995 % were deposited on an ITO-coated glass by magnetron reactive sputtering. To optimize the properties of the nano-structured CuO-Cu2O complex thin films, the deposited Cu thin films were thermally oxidized at various temperatures from 300 to 400 °C. A CH3NH3PbI3 perovskite absorber was fabricated on top of CuO-Cu2O complex thin film by a one-step spin-coating process with a toluene washing treatment. Following optimization, the maximum power conversion efficiency (PCE) exceeded 8.1 %. Therefore, the low-cost, solution-processed, stable nano-structured CuO-Cu2O complex thin film can be used as an alternative hole transport layer (HTL) in industrially produced perovskite solar cells.

基于纳米结构的 CuO-Cu2O 复合薄膜的钙钛矿太阳能电池被制备在氧化铟锡（ITO）涂覆的玻璃上并进行了研究。纯度为 99.995%的铜（Cu）薄膜通过磁控反应溅射沉积在 ITO 涂覆的玻璃上。为了优化纳米结构的 CuO-Cu2O 复合薄膜的性能，将沉积的 Cu 薄膜在 300 至 400°C 的不同温度下进行热氧化。通过一步旋涂工艺并用甲苯洗涤处理在 CuO-Cu2O 复合薄膜上制备 CH3NH3PbI3 钙钛矿吸光层。经过优化后，最高的功率转换效率（PCE）超过 8.1%。因此，低成本、溶液处理、稳定的纳米结构的 CuO-Cu2O 复合薄膜可用作工业生产的钙钛矿太阳能电池中的替代空穴传输层（HTL）。
