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 production ecological preservation. Efforts are undertook optimize engineering preparation technology OPV devices mini‐modules, through the development of low‐ecological‐impact solvent processing method. A newly developed strategy employing benign o ‐xylene (OXY) with synergistic dual additives (DIM DIB) achieved an optimal power conversion efficiency (PCE) 20.0% ( J SC 26.6 mA cm −2 , V OC 0.935 V, FF 80.3%) alongside exceptional stability metrics (82%–1500h). The mini‐module processed optimized TCE:OXY (1:3 v/v) demonstrated scalable performance reaching 17.6% (18.4 2 ), representing highest in safe based OPVs. Suitable microscale patterns contributed broader range receiving angles, enabling more flexible installation geometries building‐integrated applications.
