The hottest new technology for producing solar cel
2022-08-25- Detail
It is mainly used to test whether the materials meet the specified standards and study the performance of materials. Japan has developed a new technology for the production of solar cells
Japanese researchers recently announced that they have developed a technology for the production of solar cells by coating liquid silicon to form amorphous silicon film for the first time in the world. The new technology will help reduce the cost of thin-film solar cells
silicon is an important raw material for manufacturing, liquid crystal and solar cells. At present, solid and gaseous silicon are widely used to make the engine more efficient materials to manufacture solar cells, but the processing of solid and gaseous silicon materials costs more and takes longer time
the research team led by university professor of Beilu University of advanced science and technology, Shibata also, produced stable liquid silicon with a high molecular compound containing silicon and hydrogen as the solute in 2006. This time, based on a thorough study of the characteristics of liquid silicon, they developed this new technology for manufacturing thin-film solar cells
to produce solar cells with new technology, first remove the impurities in the liquid silicon, then drop the liquid silicon on the glass substrate in the nitrogen filled equipment, and let the substrate rotate at a high speed of about 3000 times per minute, so that the liquid silicon is evenly distributed on the substrate to form a thin layer, and finally heat it for tens of seconds at a high temperature of about 400 degrees Celsius with clear patterns and words, The amorphous silicon film with stable performance is made
repeat the above process for 3 times and add boron, phosphorus and other components to produce three layers of silicon films with different properties. After adding electrodes to produce solar cells, its power generation efficiency is about 20% of that of ordinary solar cells. Although the efficiency is not high, the cost has been reduced by 60% to 70%
at present, the research group is preparing to cooperate with domestic manufacturers in Japan to apply this technology to the production field as soon as possible
