Their wavelength of maximun absorption was 526 nm and 506 nm in solution state, repectively, and 560 nm and 522 nm in film state, respectively. Their band-gap energy was 2.01 eV and 2.09 eV in solution state, and 1.82 eV and 1.91 eV in film state, respectively. The results of analysis of the chrateristics of photovoltaics, 0.79 % and 0.99 % of the maximum power conversion efficiencies (PCE), repectively.
