제목 Triphenylamine flanked thiazole-based small molecules as donor materials for solution processed organic solar cells
초록 Two low band gap small molecules, 5,5-bis(2-triphenylamino-3 -decylthiophen-2-yl)-2,2-bithiazole (M1) and 2,5-bis(2- triphenylamino-3-decylthiophen-2-yl)thiazolo[5,4-d]thiazole (M2) based on an electron-donor triphenylamine unit and electron-acceptor thiophene–thiazolothiazole or thiophene–bithiazole units, have been synthesized for solution processed organic photovoltaic devices. The properties of small molecules were analyzed based on the UV-vis absorption spectra, and cyclic voltammetry. Photovoltaic device properties of M1 and M2 were investigated by blending of the small molecules as donors and PCBMs as acceptors with two different device architectures of conventional and inverted structures. The effect of the small molecule/fullerene weight ratio, active layer thickness, and processing solvent were carefully investigated to improve the performance of the organic solar cells.
