摘要：
Indoor photovoltaic is one of the most important applications of organic solar cells (OSCs). As different from AM1.5G sunlight with broad spectra from the visible to near-infrared region, the spectra of indoor light are usually located in the visible region. Therefore, a special material design for the photoactive layer to meet the requirement of indoor light is required for application in indoor photovoltaics. Herein, a wide-bandgap double-cable conjugated polymer is intentionally selected, which has the well-matched absorption spectra with indoor light for use in indoor OSCs. This double-cable polymer is used as a single photoactive layer in OSCs, providing a high power conversion efficiency of 19.44% under indoor light, which is comparable with the bulk-heterojunction solar cells using near-infrared electron acceptors. Moreover, the double-cable polymer-based indoor OSCs exhibit high storage stability. These results indicate that single-component OSCs based on double-cable polymers have promising applications in indoor OSCs.
