Description
Technical Field
[0001] The invention relates to the technical field of current testing, in particular to a device for testing the photoelectric conversion efficiency of a dye-sensitized solar cell. Background Art
[0002] The working principle and testing requirements of dye-sensitized solar cells (DSCs). Dye-sensitized solar cells simulate the principle of photosynthesis in nature, using a nanoporous titanium dioxide semiconductor film adsorbed with dyes as a photoanode, and selecting an appropriate redox electrolyte and platinum-plated conductive glass as a photocathode. Its working principle is as follows: the dye molecules transition from the ground state to the excited state after being irradiated by sunlight; the dye molecules in the excited state inject electrons into the conduction band of the semiconductor, and the electrons diffuse to the conductive substrate and then flow into the external circuit; the dye in the oxidized state is reduced and regenerated by the reduced electrolyte; the oxidized electrolyte is reduced after receiving electrons from the counter electrode, thus completing a cycle.
[0003] Dye-sensitized solar cells have abundant raw materials, low cost, and relatively simple process technology, which have great advantages in large-scale industrial production. At the same time, all raw materials and production processes are non-toxic and pollution-free, and some materials can be fully recycled, which is of great significance to protecting the human environment. However, in order to ensure the performance and efficiency of this type of cell, it is necessary to conduct accurate photoelectric conversion efficiency testing.
[0004] The design of the photoelectric conversion efficiency test equipment is aimed at meeting the characteristics test requirements of dye-sensitized solar cells. The equipment usually includes a miniature optical platform, a standard cell for background correction, and a fixture that can accommodate solar cells of various sizes. In addition, the equipment should be able to provide a variety of light sources, such as red light, blue light, orange light, yellow light, and white light, in order to simulate the performance of cells under different lighting conditions. During the test, the equipment can measure the current-voltage (IV) curve of the cell, as well as the intensity modulated photocurrent spectrum and intensity modulated photovoltage spectrum (IMPS / IMVS), so as to accurately evaluate the photoelectric conversion efficiency of the cell. Therefore, we designed a dye-sensitized solar cell photoelectric conversion efficiency test equipment for current detection. Summary of the invention
