日大學研發CIGS新技術 轉換效率提升兩倍!! (10/01/2015 EnergyTrend)
日本豐橋技術科學大學與產業技術總合研究所合作進行開發新型CIGS太陽能電池，並發現一種技術，能讓CIGS電池的轉換效率從6.8%提升兩倍到13.7%。詳細的研究成果已發表在期刊《Progress in Photovoltaics》之中。
據日經BP報導，由豐橋技術科學大學教授伊崎昌伸所帶領的研發團隊用鋅（Zn）取代硫化鎘（CdS）來作為CIGS電池的緩衝層材料，並採用兵庫縣的環形同步加速器Spring-8進行測試。測試發現，緩衝層會從氧化鋅與硫化鋅混和形成一層氫氧化鋅（Zn(OH)2），只要透過特殊器材讓緩衝層短時間浸泡在氨水中藉此去除氫氧化鋅層，電池整體的轉換效率就會從6.8%躍升到13.7%。
此一研究成果顯示緩衝層的化學結構對CIGS電池的轉換效率有很大的影響；若能去除氫氧化鋅層，將對轉換效率提升大有幫助。此外，此技術的技術門檻與成本都不會太高，未來可望生產沒有CdS的CIGS薄膜電池。（圖片來源：日本豐橋技術科技大學）
