Recently, Japan's Matsushita group decided to solar battery domestic production is scheduled to increase 150MW in fiscal year 2015 (April 2015 - 2016 3 months), so Panasonic solar cell total annual output will breakthrough 1GW. Panasonic group has announced it will expand the scale of domestic solar cell and module production to meet the growing demand for Japan's roof photovoltaic power generation. It is reported that Panasonic group this year will invest 9500000000 yen (equivalent to 78000000 U.S. dollars) in the island and the county and the county built a solar cell manufacturing plant and a module production plant.
July 2012, the Japanese government began to implement tariff subsidy policies to stimulate domestic renewable energy power generation market. According to the Japanese government in January 2015, the results show that the Japanese government has approved the installation of photovoltaic power generation through 71GW, in which 16.2GW has installed power generation. Internet power subsidy policy is mainly for large-scale photovoltaic power generation system, is the Japanese government called the "million photovoltaic" program.
But with the rate of decline and large areas of land increasingly scarce, Japan's domestic photovoltaic power generation investment demand has from a large area of photovoltaic power generation system steering rooftop photovoltaic power generation system. Panasonic Group believes that the "net zero energy" residential and office buildings in Japan has great prospects for development, the Japanese government and local governments in this regard is very optimistic about the enthusiasm. For rooftop solar cells, the copper indium gallium selenium thin film battery not only meets the requirements of not only recession, low cost, but also meet the needs of bending, to avoid the crystal silicon battery recession and high cost of the shortcomings.
Solar energy is a kind of clean renewable energy, more and more popular, and it has been widely used, one of which is to convert sunlight into electricity by solar cells. The utilization of solar energy is one of the new energy applications, which is an important measure to reduce the air quality and ecological environment which has been seriously damaged. As people pay more attention to clean energy, the demand for rare metals on solar cells will gradually be released.
Solar cells is mainly in the semiconductor material as the foundation, its working principle is the use of photoelectric material absorbs light energy after photoelectric conversion reaction, according to the materials used in the different solar cells can be divided into: 1, silicon solar cell; 2, with inorganic salt such as GaAs III-V compounds, cadmium sulfide, copper indium selenide multivariate compound thin film solar cell materials; 3, functional polymer material preparing solar cells; 4, nano crystalline solar cells.
It is understood that about 3% of the rare metal indium used in the manufacture of solar cells, the proportion is increasing year by year. Industry insiders expect, as the third generation of solar cells, copper indium gallium selenium thin film solar cell market in thin film solar cells this year will reach 43.3%.
Copper indium gallium selenide thin-film battery and cadmium telluride thin film battery manufacturing as the main raw materials of copper, indium, gallium, and selenium, tellurium and cadmium and other material and preparation process has no pollution problems and rare metal resources in China has advantages in downstream applications is also the largest demand side, in the technology continues to mature and suitable used thin film batteries in the family of glass and roof power will have great market space. The rapid development of copper indium gallium selenide thin-film battery and cadmium telluride thin film batteries will increase consumer demand for raw materials of indium, gallium, selenium and tellurium rare metal, also will lead to more and more enterprises and individuals on indium, gallium, such as selenium and tellurium rare metals. As the global rare metals trading volume and stock the largest spot trading platform, Pan Asia nonferrous metal exchange with proprietary trading and investment and financing function, not only become solar cell industry chain an important supply of raw materials to the end will also become the industry chain financing is important one annulus.
