Patent
YINGLI ENERGY CHINA COMPANY Ltd, Baoding Jiasheng Photovoltaic Technology Co. and YINGLI GROUP COMPANY Ltd | Date: 2012-03-06

Provided are a solar cell sheet and a heat treatment process thereof The heat treatment process includes: a) sifting from solar cell sheets after printed and sintered cell sheets with conversion efficiency lower than 18% and filling factor thereof higher than 70%; h) performing low temperature annealing on the sifted cell sheets; c) sifting from the cell sheets after low temperature annealing cell sheets with lowered filling factor; d) re-sintering the sifted cell sheets; and e) sifting from the re-sintered cell sheets cell sheets with conversion efficiency lower than 18% and returning back to b) until most or all of the sifted meet demands. The low temperature annealing and re-sintering processes proceed cyclically, low temperature annealing can repair the defects in the substrate material, and the re-sintering process can repair the defects generated from low temperature annealing, and the two processes cooperate with each other and sifting can be performed repeatedly, greatly reducing the number of low efficient sheets and improving economic benefits.
