Two novel D-A and A-D-A structural small molecule based on diphenyl pyran donor and dicyanovinylene acceptor unit have been designed, prepared, and studied for the application of organic solar cells. The UV-vis absorption spectra showed that D-A structural molecule has more extended light-harvesting ability than the A-D-A molecule and can complement with P3HT in the wavelength of 300-500 nm and 600-800 nm.
