The Cover Feature shows a near‐infrared (NIR) absorption molecule acceptor for organic photovoltaics. The newly synthesized material PTTtID‐Cl exhibits strong absorption in the NIR region (700–881 nm). The constructed organic photovoltaic device based on a polymer donor (PM7) and two non‐fullerene acceptors (IT‐4F and PTTtID‐Cl) shows a power conversion efficiency up to 12.0 %. In addition, employing the Ag/ITO/Ag microcavity structure, semitransparent colorful devices were obtained. More information can be found in the Full Paper by C.‐K. Wang, B.‐H. Jiang, et al. on page 903 in Issue 5, 2020 (DOI: 10.1002/cssc.201903087).
