Nowadays, the humanity is being in the fossil fuel energy cost to rise continually, following will be the various countries has the energy crisis concealed worry to the future, also therefore, the green renewable energy development, has became the global attention also an urgent famous doctrine. Because in each kind of green renewable energy, the solar energy electric power cannot cause the damage to the natural environment, also uses the high efficiency the solar cell to be able to reduce the electricity generation cost. Moreover, regarding the far away islands area and the power network not and the place, the solar energy electricity generation may provide the electric power which needs. Therefore, the solar energy is recognized at present as most practical and efficiency substitution energy, the solar energy market has the long-term development potential. Taiwan has the international level fossil raw material factory, the manufacturing capacity strong precision of machinery industry and the integrity semiconductor of kneading board industry. For development of the Photovoltaic (Photovoltaic, PV) provides the congenital competitive advantage, it should assurance the all opportunity of development and correlation investment tendency. This study is take the Porter diamond model as a foundation, by way of the literature analytic method, the expert interview constructs the AHP level construction, re-use of the Analytic Hierarchy Process(AHP) to integrate domestic experts and scholars for Taiwan's development of solar photoelectric direction and opinions, extracted from the Taiwan Photovoltaic Industry the critical success factors. Finally, according to research result, draw up Taiwan Photovoltaic Industry responds of development strategy, and put forth related set question and concretely suggest conducting the reference of decision by providing domestic and related operator or government, by to promote the competitive advantage of Taiwan Photovoltaic Industry.
