The United States develops new solar cells to increase the efficiency more than twice, solar batteries

Researchers at New York University in the United States are developing a new type of solar cell, using a material called perovskite, which can make the battery more than twice the energy efficiency of existing products. According to the news published on the official website of 'Nature' magazine on Sunday, this new type of battery can convert half of the solar energy absorbed into electricity, which is twice the current solar battery, so it can reduce the number of batteries required for power output, except In addition, the battery can reduce the cost of solar panels and greatly reduce installation costs, which are now the most expensive part of solar projects. The new type of battery can generate current without the need for an electric field, which can reduce the material required for the battery and at the same time produce more electricity. But the article also pointed out that this technology is still in the development stage, and there are some technical problems to be overcome. Solar cells are devices that directly convert light energy into electrical energy through photoelectric effect or photochemical effect. Once this technology is successfully invented, it will have a greater impetus for domestic photovoltaic companies, especially those that independently own photovoltaic power stations. And China also attaches great importance to solar power generation. As early as October 2003, the National Development and Reform Commission and the Ministry of Science and Technology formulated a solar resource development plan for the next five years. The 'Bright Project' of the National Development and Reform Commission will raise 10 billion yuan to promote the application of solar power technology. In November this year, the National Energy Administration issued the 'Letter on Soliciting Opinions on the Construction Scale of Photovoltaic Power Generation in 2013 and 2014.
