Metal-Less Top Electrode Semitransparent Organic Solar Modules with an Average Visible Transmission of 51% and a Light Utilization Efficiency of 4.

ABSTRACT: Semitransparent organic modules (STOMs) are of particular interest due to potential applications in building-integrated photovoltaics though upscaling without significant performance losses while ensuring an aesthetic appearance for window applications remains a major research obstacle. This study presents two types of STOMs with an area of 11.4 cm², exhibiting homogeneous appearance while retaining up to 92% of their respective small-area cell power conversion efficiency (PCE). Precise laser structuring minimized the area loss originating from the sub-cell series interconnection, allowing narrow cell stripes down to 1.25 mm. This enables a metal-less top electrode composed solely of PEDOT:PSS without compromising fill factor. For a module, an additional challenge is to ensure a
