The commercialization of perovskite photovoltaic cells has been accelerated
[Securities Times] in recent years, perovskite material is rapidly becoming a popular candidate material in Cecep Solar Energy Co.Ltd(000591) field. However, one of its main disadvantages is that it is easy to be in direct sunlight, and its performance will deteriorate over time. It is reported that scientists from the United States, China and South Korea formed a research team and successfully developed a new coating for perovskite photovoltaic panels, which is characterized by improving its stability in the sun. The research team deposited a layer of organic ions on the material to make the surface negatively charged, and then paired the positively charged ions with the negatively charged ions on the surface, which made the surface electrons more neutral and stable. The test results show that these batteries can maintain 87% of the initial photoelectric conversion efficiency in more than 2000 hours. In contrast, under the same conditions and after the same time, the performance of untreated Cecep Solar Energy Co.Ltd(000591) battery decreased to 65%.
Comments: the research laid the foundation for the commercialization and wide adoption of perovskite Cecep Solar Energy Co.Ltd(000591) battery technology, and was supported by the office of energy efficiency and renewable energy of the U.S. Department of energy. As the current mainstream photovoltaic technology, crystalline silicon photovoltaic power generation efficiency has been closer and closer to the limit. Perovskite, as a synthetic material, was first applied to the field of photovoltaic power generation in 2009. Because of its excellent performance, low cost and huge commercial value, it was rated as one of the top ten breakthrough scientific and technological advances of the year by science.
Shenzhen Topraysolar Co.Ltd(002218) ( Shenzhen Topraysolar Co.Ltd(002218) ): the company said on the interactive platform that the company has long studied the perovskite photovoltaic technology and has project reserves for project approval. The company is discussing the layout of cooperation with enterprises in relevant industries.
Gcl System Integration Technology Co.Ltd(002506) ( Gcl System Integration Technology Co.Ltd(002506) ): Suzhou GCL Nano Technology Co., Ltd., a subsidiary of GCL group, has built a pilot production line of perovskite components.
