德国梅因斯的约翰尼斯.古藤保大学在2010年7月13日发布了一项声明，宣传在提高薄膜电池效率研究方面实现了一项新的突破。电脑模拟器中显示这种被称为神秘铟镓的原材料为CIGS薄膜电池效率的提高提供了一种全新的方式。
迄今为止，CIGS电池已经可以达到了接近20%的光电转换效率，而在理论上该类电池的转换效率达到30%也是极有可能的。
Break-through for thin-film solar cells: new insights on indium-gallium
13.07.2010: Scientists of the Johannes Gutenberg-University Mainz (JGU) in Germany have achieved an important breakthrough in the search for more efficient thin-film solar cells. Computer simulations on the so called indium gallium mystery show a new way for increasing the efficiency of CIGS thin-film solar cells. Until now CIGS cells had an efficiency of about 20%, while in theory effiencies of more than 30% could be possible. …
