Four new donor-acceptor type polymeric metal complexes (P1, P2, P3, and P4) with the same Cd(II) complex in side chain and different conjugated backbone structures were synthesized by Yamamoto coupling and applied in dye-sensitized solar cells (DSSCs) as photosensitizers. The photophysical, electrochemical, and thermal properties were investigated in detail, showing that conjugated backbone containing fluorene improved intramolecular charge transfer and increased generation of photocurrent. The highest power conversion efficiency of 0.56% (J sc=1.63mAcm2, V oc=0.69V, FF=0.50) was obtained with a DSSC based on P3 under simulated air mass 1.5 G solar irradiation, which shows a new strategy to design photosensitizers for DSSCs.

The invention relates to a D (-A-pi-A) 2 type 8-hydroxyquinoline derivative and cadmium complex dye sensitizer (BDTT-VCd) as shown in a formula 1 as well as a preparation method and application of the D (-A-pi-A) 2 type 8-hydroxyquinoline derivative and cadmium complex dye sensitizer (BDTT-VCd). The dye sensitizer is a D (-A-pi-A) 2 type complex synthesized by reacting an 8-hydroxyquinoline derivative and cadmium complex with an electron donor (D) benzodithiophene bithiophene (BDTT) through Heck coupling, wherein the 8-hydroxyquinoline derivative and cadmium complex contains functional groups such as an auxiliary electron acceptor (A), a pi bridge, a main electron acceptor (A) and an anchoring group. Experiments show that a photovoltaic performance test of a dye-sensitized solar cell taking the complex as a dye sensitizer shows the following good effects that: the photoelectric conversion efficiency (PCE) reaches 8.26%; the dye thermal stability is high; the thermal decomposition temperature reaches 280 DEG C or above; the complex can meet the requirement of being used as a photovoltaic material; the complex has a certain prospect in the basic development and application aspects of dye-sensitized solar cells.
