In the Taiwanese solar power industry, the upstream industry’s lack of silicon raw materials and the downstream’s underdevelopedsystematic manufacturingstatus have led industrial development to continue concentrating on cell and module research and development manufact uring and production. Taiwan’s solar power industry has developed midstream cell manufacturersholding a share of the global market. The research period for this study was between 20 10 and 2011. This study constructed a performance evaluation model by using data envelopment analysis for the solar cell industry to assist relevant manufacturers in the Taiwanese solarpower industry in formulating operational strategies ; guidelines on future development in the industryhave been recommended .
