Abstract

The invention discloses an MoIn2S4 ternary counter electrode and a method for preparing a dye-sensitized solar cell by utilizing the same, and belongs to the technical field of solar cells. The MoIn2S4 ternary counter electrode is prepared by the following steps: adding sodium molybdate dihydrate, indium chloride tetrahydrate and thioacetamide into ultrapure water according to a mole ratio of 1:(2.0-2.1):(6-7), and fully stirring the components until the components are completely dissolved; transferring a solution into a reaction kettle equipped with FTO glass, and carrying out a constant-temperature hydrothermal reaction at 190-210 DEG C for 10-20 hours; when the reaction kettle is naturally cooled to the room temperature, taking out FTO in which an MoIn2S4 film is synthesized; and carrying out washing and drying to obtain the MoIn2S4 ternary counter electrode. The prepared MoIn2S4 ternary counter electrode and a TiO2 photo-anode film with the same substrate are assembled into a DSSC. The photoelectric conversion efficiency of the DSSC is up to 5.04% under the simulated solar irradiation of 100 mW.cm<-2>.

Description

technical field [0001] The invention belongs to the technical field of solar cells, in particular to a molybdenum indium sulfur (MoIndium Sulfur) 2 S 4 ) A ternary counter electrode and a method for preparing a dye-sensitized solar cell using the same. Background technique [0002] In the context of energy depletion day by day, in order to achieve environmental protection and sustainable development strategies, solar energy utilization has become the preferred way to meet energy demand in the future. Dye-sensitized solar cells (DSSCs) have become the best choice to replace traditional silicon-based solar cells due to their simple preparation process, low cost, high photoelectric conversion efficiency, and environmental friendliness. As the most important component of DSSCs, the cost and performance of the counter electrode directly determine the commercialization cost of DSSCs. In order to continuously reduce the cost of DSSCs and maintain or even improve the performance ...
