Semitransparent organic photovoltaic (OPV) cells promise applications in various transparent architectures where their opaque counterparts cannot contribute. Realizing practical applications of this technology requires the manufacturing of large‐area modules without significant performance loss compared to the lab‐scale devices. In this work, efficient semitransparent OPV modules based on ultrafast laser patterning on both glass and flexible substrates are reported. Solution‐processed metallic silver nanowires (AgNWs) are used as transparent top electrodes. The efficient low‐ohmic contact of the interconnects between the top AgNWs and the bottom electrode in combination with high‐precision laser beam positioning system allow to fabricate semitransparent modules with high electrical fill factor of ≈63% and a remarkable geometric fill factor exceeding 95%, respectively. These results represent an important progress toward upscaling of high‐performance OPV modules with reduced production costs.
