Towards a bright future: The versatile applications of organic solar cells

Due to the mechanical flexibility, light weight, aesthetics, absorption tunability and environmental friendliness, organic solar cells (OSCs) have superior application potential over their inorganic counterparts including silicon and perovskite solar cells (PSCs). Thanks to these benefits, the past decade have witnessed the rapid growth of flexible OSCs, semitransparent OSCs and indoor OSCs. In this progress report, we firstly overview the recent advance of the applications of the three promising OSCs. Subsequently, we sketch the critical points for the three classes of OSCs and highlight the efforts paid by the research community to address these issues. Besides, we discuss some popular strategies to afford great performance of each kind of OSC, respectively, and underline the corresponding breakthrough directions. Last but not least, we present the remaining challenges for advancing the commercial applications of these three classes of OSCs.
