Japan steel plates and Industrial Science and Technology Research Institute (hereinafter referred to as the middle class & Research Institute) using a new metal frame with low cost,Vostro 1400 battery , the process of CIGS (copper indium selenide Gallium) solar cells, its conversion efficiency higher than 16.7%. Japan Steel plans in 2011 to allow the development of metal around the bottom to reach commercialization.
CIGS solar cells on thin-film type conversion efficiency of solar cells higher, both companies believe that the solar cell can be a solar cell silicon crystal, after the new battery. Film CIGS solar cells so that the bottom had to use more glass is currently available for the sweetness of solar cells, developing a film about the technology of metal chassis. It is reported that previous studies of hard metal floor for most of CIGS solar cells have a negative impact of the titanium sheet and foil based on molybdenum, but substantive, it is a zone of wholesale supply characters and issues of cost. To answer these questions, the two companies also consider the use of low cost stainless steel sheet, but the high temperature film solar cells, the metal frame elements that can spread to the layer of CIGS, it n ‘There has serious consequences on the efficiency of electricity generation.
The Japan Steel has developed a cost may be lower than the sheet steel of low carbon stainless steel base metal thin soil. Below the initial price of steel sheet with low titanium dioxide 1 / 10, about half of the sheet of stainless steel, polyimide film on 1 / 4.
The effect on the effectiveness of elements of CIGS solar cell proliferation, the two companies through the formation of an independent film surface treatment to control. The film surface treatment can shoot in the atmosphere can support low-cost technology.
The conversion efficiency of CIGS solar cells product reaches the highest level of global production capacity and Research Institute was to promote the metal chassis-based development of flexible solar cells.sony vgp-bps9 , In addition, also works on developing large-area modules. Japan steel production and the Research Institute with the development of a low-cost film with a surface treatment of a metal chassis prototype CIGS solar cells, the small unit area conversion efficiency of 16.7 % (conversion efficiency intrinsic area power generation cell of about 0.5cm2). The conversion efficiency “is used when the high-performance motherboards at low cost ‘
