The major challenges associated with bringing organic solar cells (OSCs) to the industrial market are to further improve power conversion efficiency (PCE), device stability, and green-solvent processability within an open-air (OA) environment. High-performance OSCs based on various active layers are realized by employing H75-2F among newly formulated cathode interfacial materials (CIMs), achieving not only a prominent PCE of up to 19.44% (certified 19.27%) under controlled processing conditions, but also exceptional device stabilities (e.g., shelf stress (T₉₅ = 1000 h), thermal stress (T₈₀ = 300 h), illumination (T₈₀ = 500 h), and moisture exposure (T₈₀ = 300 h)). Moreover, we also demonstrate an OA, green-solvent processed efficient H75-2F-based OSC with 17.78% PCE (certified 17.64%), representing the highest value for OA-processed OSCs in all-green systems. A comparative study of the CIM series reveals the underlying mechanisms correlated with macroscopic and microscopic morphologies, demonstrating the key features of simultaneous favored control for the fabrication of efficient OA-processed OSCs.

将有机太阳能电池 (OSC) 推向工业市场的主要挑战是进一步提高露天 (OA) 环境中的功率转换效率 (PCE)、器件稳定性和绿色溶剂加工性能。通过采用新配制的阴极界面材料（CIM）中的H75-2F，实现了基于各种活性层的高性能OSC，不仅在受控加工条件下实现了高达19.44%（认证为19.27%）的显着PCE，而且还具有优异的性能器件稳定性（例如，储存应力（ T ₉₅ = 1000 h）、热应力（ T ₈₀ = 300 h）、照明（ T ₈₀ = 500 h）和湿气暴露（ T ₈₀ = 300 h））。此外，我们还展示了一种 OA、绿色溶剂处理的基于 H75-2F 的高效 OSC，其 PCE 为 17.78%（认证为 17.64%），代表了全绿色系统中 OA 处理的 OSC 的最高值。 CIM 系列的比较研究揭示了与宏观和微观形态相关的潜在机制，展示了同时有利控制制造高效 OA 处理 OSC 的关键特征。
