We demonstrate a D–A–π–A sensitizer with a benzothiazole–cyclopentadithiophene moiety as the spacer in a triphenylamine dye for dye-sensitized solar cells. The dye has a broad light absorption range up to 800 nm. A power conversion efficiency >9% has been achieved using a [Co(bpy)3]2+/3+-based electrolyte.
Binary OSCs with an efficiency as high as 15.17% are prepared using a new acceptor with a 3,5-bis(trifluoromethyl)phenyl as the N-substituent in a benzotriazole core and a donor polymer.
