Abstract

Thin film organic photovoltaics (OPVs) aim to harness solar energy environmentally friendly, highly efficient, and cost-effective means, thereby offering a sustainable solution for energy production and ecological preservation. Efforts are undertook to optimize engineering preparation technology for OPV devices and mini-modules, through the development of low-ecological-impact solvent processing method. A newly developed solvent engineering strategy employing environmentally benign o-xylene (OXY) with synergistic dual additives (DIM and DIB) achieved an optimal power conversion efficiency (PCE) of 20.0% (J_SC of 26.6 mA cm⁻², V_OC of 0.935 V, FF of 80.3%) alongside exceptional stability metrics (82%–1500h). The mini-module processed with optimized TCE:OXY (1:3 v/v) solvent demonstrated scalable performance reaching 17.6% (18.4 cm²), representing the highest performance achieved in the development safe solvent based OPVs. Suitable microscale patterns contributed to a broader range of receiving angles, enabling more flexible installation geometries for building-integrated applications.

有机太阳能电池制造中溶剂毒性降低20%效率

薄膜有机光伏（opv）旨在利用太阳能环保，高效，成本效益的手段，从而为能源生产和生态保护提供可持续的解决方案。通过开发低生态影响的溶剂处理方法，致力于优化OPV器件和微型模块的工程制备技术。新开发的溶剂工程策略采用环境友好的邻二甲苯（OXY）和协同双添加剂（DIM和DIB），实现了20.0%的最佳功率转换效率（PCE）（JSC为26.6 mA cm - 2， VOC为0.935 V， FF为80.3%）以及出色的稳定性指标（82%-1500h）。经过优化的TCE:OXY （1:3 v/v）溶剂处理的迷你模块显示出可扩展性能达到17.6% (18.4 cm2)，代表了开发安全溶剂基opv的最高性能。合适的微尺度模式有助于更广泛的接收角度范围，为建筑集成应用提供更灵活的安装几何形状。
