Light Managements and Transparent Electrodes for Semitransparent Organic and Perovskite Solar Cells

Comparing with inorganic solar cells, organic solar cells and perovskite solar cells have attracted considerable attention owing to their unique properties such as the color tunability of their photoactive layers, low cost, catering to solution processing, and flexibility, which have been considered as the most promising technologies in wearable energy resources and show huge potential in fabricating transparent devices. In recent years, numerous light coupling constructions and transparent electrode optimization strategies have been applied to further enhance device photoelectric performance. In this review, common strategies focusing on light modulation and for semitransparent organic solar cells and semitransparent perovskite solar cells, which are crucial to increase J sc , achieving adjustable chromaticity coordinates, high average visible transmittance and color rendering index have been summarized in detail.
