Achieving large-area organic photovoltaic (OPV) modules with reasonable cost and performance is an important step toward commercialization. In this work, solution-processed conventional and inverted OPV modules with an area of 216 cm were fabricated by the blade coating method. Film uniformity was controlled by adjusting the fabrication parameters of the blade coating procedure. The influence of the concentration of the solutions of the interfacial materials on OPV module performance was investigated. For OPV modules based on the PM6:Y6 photoactive layer, a certificated power conversion efficiency (PCE) of 9.10% was achieved for the conventional OPV modules based on the TASiW-12 interfacial layer while a certificated PCE of 11.27% was achieved for the inverted OPV modules based on the polyethylenimine (PEI) interfacial layer. As for OPV modules based on a commercially available photoactive layer, PV-X Plus, a PCE of 8.52% was achieved in the inverted OPV modules. A halogen-free solvent, -xylene, was used as the solvent for PV-X Plus, which makes the industrial production much more environmentally friendly.
实现具有合理成本和性能的大面积有机光伏 (OPV) 模块是商业化的重要一步。在这项工作中，通过刮刀涂布法制备了面积为 216 cm 的溶液处理常规和倒置 OPV 模块。通过调整刮刀涂布工艺的制备参数来控制薄膜的均匀性。研究了界面材料溶液浓度对 OPV 模块性能的影响。对于基于 PM6:Y6 光活性层的 OPV 模块，基于 TASiW-12 界面层的常规 OPV 模块实现了 9.10%的认证功率转换效率 (PCE)，而基于聚乙烯亚胺 (PEI) 界面层的倒置 OPV 模块实现了 11.27%的认证 PCE。对于基于市售光活性层 PV-X Plus 的 OPV 模块，在倒置 OPV 模块中实现了 8.52%的 PCE。-xylene 是一种无卤溶剂，被用作 PV-X Plus 的溶剂，这使得工业生产更加环保。
