First Results on Industrialization of Elkem Solar Silicon at Pillar JSC and Q-Cells

摘要: After the development of Elkem Solar Silicon process, Q-Cells AG, Pillar JSC and AS have started qualification program for on solar cells out an industrial manufacturing process large scale. In presentation details status most recent results from test are given. The in pilot plant is terms scale-up factors critical equipment very close to planed production A significant amount was converted ingots, wafers cells, using standard slightly modified processes. material yield volumes shipped AG comparable virgin poly-silicon taking into account specifications. a block level confirmed same lifetime levels as blocks made reference. Results multicrystalline demonstrate average efficiencies well above 15% no difference compared Finally potential application ESS feedstock future high efficiency cell concepts addressed.
