Integrated Effciency Engineering in Solar Cell Mass Production

  • In order to promote solar cells to be a competitive source of electrical energy in the future, a structured optimization methodology is necessary in mass production. On the one hand it accelerates development for established cell concepts in order to reach higher conversion efficiency and thus lower cost per Watt. On the other hand also new technologies depend on a structured approach for efficiency engineering to enable substantial evaluation and fast implementation. The real potential of any cell technology is only shown by efficiency engineering in mass production. In this study, the established optimization approaches of Quality Management and Six Sigma have been adapted for the solar cell industry. This led to a proposed procedure for efficiency engineering, formulated as nine steps of process optimization. This methodology was implemented in the mass production of the commercial solar cell manufacturer Q-Cells SE in Thalheim (Germany), and was successfully validated with results in stabilization, cell conversion efficiency and process knowledge. By implementation of the structured approach, the speed of improvement could be significantly increased in the concerned production line.
