New York University researchers are developing new types of solar cells that use a material called perovskite that can make batteries more than twice as efficient as existing products.
According to news published on the official website of Nature magazine on Sunday, this new type of battery can convert half of the absorbed solar energy into electricity, which is twice the current level of solar cells, and therefore can reduce the number of batteries required for power output. In addition, the battery can reduce the cost of solar panels, significantly reducing the cost of installation, and the cost of installation is now the largest part of the cost of solar energy projects.
The new battery can produce electricity without an electric field, which can reduce the materials needed for the battery and produce more electricity. However, the article also pointed out that this technology is still in the development stage, and some technical problems still need to be overcome.
Solar cells are devices that directly convert light energy into electrical energy through photoelectric effects or photochemical effects. Once this technology is successfully invented, it will have a greater impetus for domestic photovoltaic companies, especially those that own photovoltaic power stations. 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 energy resource development plan for the next five years. The Development and Reform Commission “Bright Project†will raise 10 billion yuan to promote the application of solar power generation technology. In November this year, the National Energy Administration issued the “Letter to Solicit Views on the Scale of Photovoltaic Power Generation in 2013 and 2014â€, requesting that the construction scale of photovoltaic power generation be increased by 20% to reach 12GW in 2014 without the occurrence of abandonment of light and electricity. .
Domestic photovoltaic listed companies mainly include Hairun Photovoltaic and Aerospace Electromechanical. In June 2012, Hairun Solar invested in the establishment of Keping Hairun Photovoltaic Power Generation Co., Ltd. and conducted 20MW photovoltaic power generation project construction. At the same time, Jinchang Hairun Photovoltaic Power Generation Co., Ltd. was established and Jinchang Hairun conducted 20MW photovoltaic in Jinchuan Jinchuan District. Construction of power generation projects.
52% of Shanghai Aerospace Technology's Shanghai Solar Energy Technology has built the first 10-kilowatt solar power plant in China, and has the largest solar energy facility production plant in the country, with a production capacity of 10 megawatts. It has also reached Sharp's solar cell module production processing agreement with Sharp.
