Advances and Prospects for Semitransparent Organic Photovoltaics

This is the authors' abstract. We don't add key points for this paper.

Organic semiconductors exhibit discontinuous absorption spectra owing to the inherent characteristics of molecular orbitals, which enables organic photovoltaics (OPVs) to have a promising application: semitransparent OPVs (ST-OPVs). Benefiting from the materials development and device engineering, the performance of ST-OPVs has rapidly progressed, achieving 12.19% power conversion efficiency (PCE) and 49.62% average visible transmittance (AVT) for small active area devices and 6.7% PCE and 32.9% AVT for 100 cm 2 large-area modules. This Perspective overviews recent progress in ST-OPVs, detailing innovative strategies in active layer design, transparent electrodes, interface engineering, and optical management. Facing the upcoming application requirements for ST-OPVs, the advancements of large-area, stable ST-OPVs as well as the studies on application potential and benefits of ST-OPVs are also covered. Lastly, the key challenges that need to be addressed and research directions facing the future commercialization of ST-OPVs are also discussed.
