A new X-type, structurally twisted, highly soluble TAB-BODIPY based electron acceptor (BDY) is designed and synthesized. Organic solar devices are fabricated using poly(3-hexylthiophene-2,5-diyl) (P3HT) as donor polymer and BDY as an electron acceptor. A promising power conversion efficiency of 4.46% is obtained for this new class of acceptor, which is the first-ever reported on TAB-BODIPY as a non-fullerene acceptor in organic solar cells. © 2021 International Solar Energy Society
