Novel polymeric metal complexes as dye sensitizer for dye-sensitized solar cells (DSSCs) based on poly thiophene containing complexes of 8-hydroxyquinoline with Zn(II),Cu(II), and Eu(III) in the side chain have been synthesized according to the Stille coupling method and characterized by FTIR, GPC, and Elemental analysis. The UV-vis absorption spectroscopy, photoluminescence spectroscopy, cyclic voltammetry, and the applications in dye-sensitized solar cells (DSSCs) are also determined and studied. The DSSCs fabricated by PZn(Q)2-co-3MT, PCu(Q)2-co-3MT, and PEu(Q)3-co-3MT exhibit good device performance with a power conversion efficiency of up to 0.56%, 0.78%, and 1.16%, respectively, under simulated AM 1.5 G solar irradiation (100 mW/cm2). They possess excellent stabilities and their thermal decomposition temperatures are 340 °C, 400 °C, and 540 °C, respectively, indicating polymeric metal complexes are suitable for the fabrication processes of optoelectronic devices.

Three donor-π-acceptor (D-π-A) dyes (P1-P3) of polymeric metal complexes were synthesized for application in dye-sensitized solar cells (DSSCs). These D-π-A sensitizers use Phenothiazine appended with octyl as donor (D), C=C bond as π-bridge(π), and thiophene-phenanthroline metal complexes as acceptor (A) that can be anchored to the TiO2 surface. They have been characterized and studied by FT-IR, GPC, Elemental analysis, TGA, UV-vis absorption spectroscopy, photoluminescence spectroscopy and cyclic voltammetry. When applied in the DSSCs, the sensitizer P1 exhibits the best energy conversion efficiency of 1.57% (Jsc = 4.12 mA/cm2, Voc = 0.62 V, FF = 61.7%) under simulate AM 1.5G solar irradiation. The TGA data show that these new dyes own good thermal stability. These results will facilitate the understanding of the crucial importance of molecular engineering and pave a new path to design novel conjugated organic polymer dye for highly efficient and stable DSSCs.

The invention discloses a phenothiazine-containing polymerization metal complex as well as a preparation method and an application thereof. The phenothiazine-containing polymerization metal complex is a novel dyestuff with a phenothiazine-thiophene side chain type D-pi-A structure. Compared with a conventional precious metal dyestuff, the novel dyestuff has the advantages of low cost, simple preparation, relatively high yield and good thermal stability and can be applied to dye-sensitized solar cells.
