Abstract
Semi-transparent organic photovoltaics (ST-OPVs) are considered as an attractive solution for power-generating windows. Typically, the module geometric fill factor (GFF) is limited by low-resolution patterning approaches. Here, we demonstrate a solvent-free polymer-based peel-off patterning method, which can achieve the resolution of photolithographic patterning of chemically sensitive organic materials. An ~13 cm² ST-OPV module fabricated using this method, achieves GFF > 95%, and a power conversion efficiency approaching 8% which shows less than 10% loss compared to a 4 mm² device. This method enables a viable path for achieving ST-OPVs at larger scales.
