由於世界的扁平化，全球商業競爭不斷地愈演愈烈，唯有持續創新才能夠永續企業的競爭能力。在今日全球氣候變遷與環保議題壟罩的時代，太陽能被視為最具能夠節能減碳與緩和溫室效應的替代能源，可以預期的是太陽能產業將為近代之明星產業，更是擁有高科技半導體與光電產業的台灣搶入該產業之大好契機。由於矽原料與主要技術主要掌握於美日歐大廠，台灣企業必須活用技術預測之方式以策略性掌握太陽能產業，本研究採用共詞分群方法於分析太陽能專利並搭配科技預測的工具來呈現目前的太陽能技術成熟度與預測未來最具前瞻性之太陽能電池。本研究之結果顯示，CdTe, CIS/CIGS與 Group III-V 太陽能電池將因稀有金屬產量有限而限制其長遠技術發展，而主要大宗的矽太陽能電池若無法近期解決當前的矽原料短缺之問題，新興太陽能電池將最受矚目成為未來之主流技術。

Driven by globalization, business enterprises have since been growing in exponential rates to gain competitiveness, and the only way for a company to gain a strong foothold in the industry is through the innovation and development of new products and services.
This is especially crucial in the energy sector, where solar cell technology is expected to be one of brightest advanced industries and also one of potential chances for the Taiwanese high-technological (hi-tech) companies to keep up with global competitiveness through its strong backing by the established strong semiconductor and optoelectronics industries.
This research paper proposes the use of the “Overlapping Co-clustering” approach to first enhance the suitability of current technology classification and then integrate the use of technology forecasting tools to increase the reliability and accuracy for technology forecasting. In the meantime, these tools can also be used to demonstrate current technology in solar cell development and future movements.
Research findings shows that the current silicon shortage causes obstruction in the potentiality of silicon-type solar cells. Moreover, development of the CdTe, CIS/CIGS and Group III-V is contrained by the decreasing availability of scarce mentals. From current findings, the emerging PV is expected to become the future solar cell in the long run due to its environmentally-friendly characteristics.
