Solar cell production has served as the most important link in solar photovoltaic¡]PV¡^ supply chain from upstream silicon raw material and wafer supply to downstream module and system installation. The PV industry enjoyed a miraculously rapid growth in recent years with Taiwan ranking No. 4 in global solar cell production in 2008. However, in the wake of the financial storm, the industry has gone through some unprecedented changes in the market due to the severe global demand shrinkage. Looking ahead, challenges also lie in product assimilation and profit erosion. Difficulty will increase with market concentration and global operation; while the low yield of capital investment in R & D in the new industry adds on the pressure, too. This thesis proposes a four-step global development strategy for Taiwan solar cell industry after a SWOT analysis. Producers are advised to exert current strengths in developing tolling business in the short term for elevating uptime and capacity, while, in the long run, they should coordinate more efforts in brand-building and innovation for differentiation. Efforts should also be persisted to strengthen linkage within the supply chain and to extend ties with the government, end market, or other industries to create better synergy. Meanwhile, the government is expected to provide incentives for strategic research, to assist in cross-business alliance with Taiwan leading IT technologies and to bridge between the two sides of the Taiwan Straits for enhanced cooperation in solar PV industry, to ensure Taiwan¡¦s firm grip in the rising industry of global alternative energy.
