Abstract

A-D-A architectured quinoxaline and bezodithiophene based small molecule exhibiting low band gap was designed and synthesized for bulk heterojunction solar cell application. Two dimension conjugation to the molecule was imparted by using alkylated aromatic units. This effective extension of conjugation broadens the absorption spectra. Optical and electrochemical properties suggest that the synthesized molecule has a low band-gap and well matching frontier molecular orbital energy levels with that of PCBM. A photovoltaic device using this A-D-A molecule as the active layer was fabricated to evaluate the optoelectronics properties.
