Underlying effects of diiodooctane as additive on the performance of bulk heterojunction organic solar cells based small organic molecule of isatin-core moiety

Abstract This paper reports the synthesis of D-A type π-conjugated organic chromophore, 1-hexyl-5-(5′-hexyl-[2,2′-bithiophen]-5-yl)indoline-2,3-dione (RBTh-NR) using isatin-core moiety as strong electron-acceptor and terminal alkyl bithiophene as electron-donor. The synthesized RBTh-NR chromophore was utilized as donor material for the ...More
