The Australian National University announced on the 5th that the scientists of the university for the first time achieved a photoelectric conversion rate of perovskite solar cells of more than 26%. This achievement can significantly reduce the cost of solar power generation, and the application of solar cells becomes more extensive. At present, in the solar cell market, crystalline silicon cells account for 90%. Because its cost is still higher than other energy sources, scientists all over the world are always looking for more efficient and economical solar cell materials. Scientists at the Australian National University have recently used a composite material, perovskite, as a solar cell material whose crystal structure helps it absorb light better. The National University of Australia at the Australian National University of China who participated in the study said that the crystalline silicon solar cell needs crystalline silicon to have a thickness of several hundred microns, and the perovskite only needs several hundred nanometers to absorb all light, and calcium The titanium ore material loss is very few in the manufacturing process, so its manufacturing cost is very low. Professor Kelly Keachport, who led the study, said that crystalline silicon solar cells have a certain efficiency limit, but perovskite solar cells are much better at absorbing light and can obtain higher voltages. The photoelectric conversion rate of more than 26%, in the solar cell field is a high conversion rate, so perovskite as a solar cell material prospects.
