Lowering Toxicity of Solvent in Organic Solar Cells Manufacturing for 20% Efficiency
Abstract
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 cm 2 ), 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.
