Centrotherm photovoltaics AG has announced that its thin-film sector has been successfully Centrotherm patent will be based on the equipment and technology conversion efficiency of thin film solar cells to 13%. The results of the process was also used for large-scale mass production, and it is expected that the 1.5m ² for the manufacture of thin film components of the turnkey lines can reach 12% efficiency.
Centrotherm photovoltaics solar silicon, crystalline silicon thin-film CIGS solar cells and components of the production equipment and technology providers, is committed to the film sector to reduce the cost per watt of solar cells. Centrotherm have in the CIGS thin-film technology leading conversion efficiency, can provide customers high-efficiency, lower production costs. In addition, with other manufacturing techniques, the new manufacturing process for CIGS components of the process does not require toxic gases.
"Has been obtained in the laboratory, the efficiency of thin-film components demonstrated the potential advantages of the technology. However, the current challenge is how to make the technology from the laboratory into mass production in large-scale," Centrotherm photovoltaics's CTO Peter Fath Dr.说. "We in the CIGS technology has the advantage of being simple and robust process management, and easy to choose from small-volume production line process into more steps."
Centrotherm photovoltaics Group Blaubeuren have CIGS a complete production line, from 2008 pre-production film components 0.1m ², and R & D experimental film here.
Blaubeuren experts from the use of 1.5m ² of photovoltaic components, because it can target to achieve the optimal efficiency of production and assembly costs, and thus enable customers to long-term access to highly competitive production conditions. Components using the glass - the glass sandwich structure, and based on the company's patented two-step process. A first step, remove the metal workshop in the sputtered film. CIGS phase transformation occurred in the second heat treatment steps. Process management enables efficiency was greatly improved and at the same time reducing production costs. "Despite our success is still in its initial stage, but it shows that our R & D investment and expansion of walking in the right direction," Fath said.
Centrotherm over the first set of annual production capacity of 30MW of CIGS thin-film battery turnkey production lines have been a customer in Asia to adopt, and rapid mass production. The goal is that in 2009 the use of 1.5m ² of substrate manufacturing, which will be the first, currently the largest manufacturer in the mass production of CIGS components.
