The generation of energy by renewable sources, such as solar technology, for example, has increased in recent years as a way to guarantee current consumption without compromising the natural resources and the needs of future generations. Performance under low light intensity makes the dye-sensitized solar cell (CSSC) promising for internal applications in autonomous electronic devices. But for this technology to be competitive, it is essential to improve efficiency and stability and reduce manufacturing costs, with a sustainable life cycle. In this sense, the objective of this research was the development and application as a sensitizer in a solar cell of the [(μ-antrarufinate)Zn2(1,10 ́phenanthroline)4] 2+ (ZnA) complex, which was synthesized and structural confirmation based on molar conductivity, and elemental and spectral analysis by IR, UV-Vis and NMR-H. The cell was mounted in a TiO2/ZnA/ I3 /I/carbon configuration and the performance tested. The complex is stable in the solid state, has good solubility in organic solvents and has absorption bands at 544 and 608 nm. The 21.2% yield in the conversion of solar energy into electrical energy suggests the potential of ZnA as a sensitizer in a CSSC cell.
