The Optimization of Transparent Organic Photovoltaic Cells

As an emerging technology, transparent organic photovoltaic cell (TOPV) has the potential to diversify the applications of solar energy and extend its reach to additional fields. In the last dozen years, a multitude of innovative TOPVs have been crafted. Excellent TOPVs exhibit superior electrical conductivity and notable visible light transmittance, leading to increased power conversion efficiency (PCE) and average visible transmittance (AVT). In order to summarize the achievements of the existing technology of TOPV and provide directions for its future development, this review is authored. It revolves around three aspects: optimizing PCE and AVT separately and balancing high PCE and AVT concurrently. This review offers professional optimization strategies for the aforementioned three aspects and provides an overview of the most recent advancements in the field of TOPVs. Through the research results, PCE and AVT of TOPVs are developing rapidly and with remarkable success due to a variety of production processes, device engineering and material inventions. Nevertheless, the investigation and advancement of electrode materials and processes, the adjustment of rear electrode structures and the innovation of active layer materials to improve photon capture efficiency and transmittance in the visible range all hold great prospects.
