| Summary: | 碩士 === 中原大學 === 企業管理研究所 === 99 === The main energy resources utilized today are fossil fuel energy, such as petroleum, coal, natural gas, or radioactive nuclear energy. In recent years, unlimited extraction and use of fossil fuel energy has not only forcing the energy storage to become empty but also seriously affected the ecological balance of the earth. Because the impact of power resource shortage and the trend of environment protection in recently, the solar photovoltaic industry has became a target industry, photovoltaic solar power generation has been considered as one of the most important policies in many develop country. Particularly in the III-V Group HCPV power system, it’s high photoelectric conversion efficiency and the process not produce pollution, so the development trend of the future energy industry.
This study useing USPTO database to analyze III-V Group high concentration photovoltaic patent map, which help understand the developing trend of this technique. And in using of user-orientation demand direction to explore the demand survey of current plants for the utility of III-V Group high concentration photovoltaic. By doing this, we can estimate and summarize the effectiveness of user-orientation demand. At the same time, we can understand whether there are differences between the user-orientation demand and utility demand which we getting from the utility matrix of patent technology. The empirical result shows that the supply side of technology mostly considering in how to change its material properties to enhance the efficiency of photovoltaic conversion. However, it is always to consider the economical concern for the market demanded. There is an apparent gap between the two sides for the utility of technology. It maybe the critical basis for the layout of future R&D.
