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

摘要

The technical field to which the invention pertains is organic materials. Thiophene-containing organic photoelectric materials which include compounds shown by structural formula (I) are provided, 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 and represent an 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 are provided. Due to the fact that thiophene rings and cyano groups are included, the above thiophene-containing organic photoelectric materials have broader spectrum respondent, better thermal stability and environmental stability.
