On June 12, Taiwan Caixin Energy Technology Co., Ltd. and the Panzhihua City Government of Sichuan Province formally signed a letter of intent for investment and cooperation and plans to invest 200 million U.S. dollars to build the first CIGS (copper-indium-gallium-selenium) solar thin-film battery project in the city. Taiwan Caixin Energy Technology Co., Ltd. has advanced technologies and rich experience in the development and utilization of solar energy. Its products, CIGS solar thin-film batteries, have been put into large-scale production and are at the leading level in the world. Panzhihua has a three-dimensional climatic type in the south subtropical zone of the Panzhihua region. The temperature difference between day and night is large, the climate is dry, the sunshine is long, and the solar radiation is strong. This provides sufficient energy guarantee for the development and utilization of solar energy. The development and use of solar energy is a key new type of energy that the country encourages development. CIGS battery has stable performance and strong anti-radiation ability. The photoelectric conversion efficiency is currently the first of all thin-film solar cells, and it is close to the conversion efficiency of crystalline silicon solar cells currently in the mainstream market. The cost is 1/3. It is because of its excellent performance that it is internationally known as the next generation of cheap solar cells, and it has a broad market prospect.
