Study of Thermal Treatment on Properties of Polycrystalline Silicon Wang Wenjing1,Ma Lifen2,Ren Bingyan2,Gou Xianfang2,Xu Ying1,Li Xudong1 (1.Beijing Solar Energy Research Institute, Beijing 100083, China;2.Institute of Information Function Materials, Hebei University of Technology, Tianjin 300130, China) Abstract:The effects of thermal annealing on oxygen behavior and carrier lifetimes of mc......
W/(m?K)). While Si content is 11.7%, the average thermal conductivity declines markedly to 87.74 W/(m?K). The annealing treatment is better than the solution aging treatment in reducing CTE..., a few Si element can be separated out of Al matrix alloy under the annealing treatment, which will cause electron scatter seriously during heat conduction, therefore, lead to the decrease of the thermal......
