THIOPHENE-CONTAINING ORGANIC PHOTOELECTRIC MATERIALS, THEIR PERPARATION METHODS AND SOLAR CELL DEVICES

摘要

The present invention relates to the technical field of organic materials. Thiophene-containing organic photoelectric materials are provided, which comprise compounds shown by structural formula (1), wherein R1, R2, R3 and R4 are the same or different and represent hydrogen or straight, branched or cyclic alkyl containing 1 to 12 carbon atoms, m, n and p are the same or different integer between 0 and 6. Preparation methods of these thiophene-containing organic photoelectric materials and solar cell devices containing the above thiophene-containing organic photoelectric materials also are provided. Due to the fact that thiophene rings and cyano groups are included, the above thiophene-containing organic photoelectric materials have broader spectra respondence, better thermal stability and environmental stability.
