Paragraph 0005, (2021/01/30)
The invention relates to a D (-A-pi-A) 2-type imine derivative and 8-hydroxyquinoline derivative cadmium complex dye sensitizer (BDTT-PCd) as shown in a formula 1, a preparation method and applicationthereof. The dye sensitizer is a D (-A-pi-A) 2 complex synthesized by reacting an imine derivative containing functional groups like an auxiliary electron acceptor (A), a pi bridge, a main electron acceptor (A), an anchoring group and the like with an 8-hydroxyquinoline derivative cadmium complex and an electron donor (D) benzodithiophene bithiophene (BDTT) through a Heck coupling reaction. Experiments show that the dye-sensitized solar cell taking BDTT-PCd as the dye sensitizer shows good effects in photovoltaic performance tests: the photoelectric conversion efficiency (PCE) reaches 8.82%,the dye thermal decomposition temperature reaches 320DEG C or above, the thermal stability is high, the requirements of photovoltaic materials can be met, and the dye sensitizer has certain prospectsin development and application of dye-sensitized solar cells. The structure of the complex BDTT-PCd is shown as formula 1 in the specification.
