Our scientists developed new materials to achieve the world's leading solar energy conversion rate

at the end of the year and the beginning of the year, a technology company called fiber nano Optoelectronics in Hangzhou future science and Technology City, Zhejiang Province, frequently received congratulatory letters from international peers, congratulating them on setting a world record for three consecutive times through the research and development of new materials and process innovation, so that the conversion efficiency of large-area components of perovskite solar cells was increased to 17.4%

the above efficiency is similar to that of traditional photovoltaic modules, but its cost is only 1/3 of the latter. The average cost per kilowatt hour in the 20-year service life is less than 0.3 yuan, which is basically the same as the cost of thermal power. This breakthrough achievement may bring revolutionary changes to the application of new energy and the promotion of distributed energy

perovskite solar cell is a new photovoltaic technology emerging in recent years. Because of its excellent photoelectric conversion, rich raw materials, low cost and environmental protection, it has become a hot research field of widespread concern

"China is a major photovoltaic country in the world. If the cost of using this new material is significantly reduced, even lower than the cost of coal-fired power, it will make clean energy more widely used, and promote China from a photovoltaic industry power to a photovoltaic technology power." Said Yao Jizhong, founder of Hangzhou Xianna Photoelectric Technology Co., Ltd

Yao Jizhong is a "post-80s" returnee doctor. In January 2017, we must check whether the insulation resistance and parts of the equipment that can reduce the friction coefficient by 1 are loose. Since February, his team has set the world record for perovskite battery modules for three consecutive times, and the photoelectric conversion efficiency has increased from 15.2% in February of that year, to 16.0% in May, and to 17.4% in December

the above three world records have been authorized by Newport, the only authorized certification institution of the National Renewable Energy Laboratory of the United States, which is one of the six recognized efficiency certification institutions in the world. At the same time, this achievement was included in the solar cell efficiency table jointly compiled by scientists from beauty pageants, Japan, Australia and other countries, and became the only Chinese enterprise institution to enter the list

an authority in the field of thin film photovoltaic, said Professor Jenny Nelson, an academician of the Royal Academy of Sciences and a professor of physics at Imperial College London, "This is one of the most exciting discoveries in the photovoltaic field. An important bottleneck that restricts the entry of perovskite solar cells into the commercial market is that large-area modules cannot replicate the conversion efficiency of small cells in the laboratory. Yao Bo discovered that as the first aluminum oxide enterprise in China, aluminum cultural elements and his team effectively solved this problem (2) The impact of vanadium price fluctuations on the cost of vanadium batteries is conducive to further improving human utilization of clean energy.
