現今所使用的能源,大多為石油、天然氣等會排放溫室氣體之石化能源(Fossil Energy)或具放射性汙染之核能,多年來由於無限制的開採利用,不僅使全球能源存量面臨即將用盡的時刻,也影響了地球的生態平衡。近幾年隨著能源短缺的影響和環境保護的興起,太陽能發電裝置是各國政府近年來在光電產業發展的重要項目之一,並且已成為世界各先進國家努力的目標。尤其以III-V族高聚光型太陽能技術 (III-V Group High Concentration Photovoltaic, HCPV)發電系統,因具有高光電轉換效率以及發電過程不會產生污染等功效,因此成為未來能源產業發展趨勢。 本研究以美國專利暨商標局(United States Patent and Trademark Office, USPTO)資料庫進行III-V族高聚光型太陽能技術專利地圖分析,以瞭解目前此技術之發展趨勢,並以使用者需求導向探討目前發電廠(使用者)對於III-V族高聚光型太陽能技術功效需求之問卷調查,以統計並歸納使用者的功效需求;同時透過專利技術功效矩陣所得到之功效需求與使用者需求之間是否存在差異。經實證結果顯示,技術供給面大多以如何改變材料性質提高光電轉換效率,而對於市場需求者所考慮功效以成本考量為優先,兩者之間對於技術功效明顯的差距,可做為接下來技術研發佈局重要的依據。
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.
