Outline of Research at the Start

本研究では、従来の単接合型太陽電池を遥かに凌駕する性能が期待される多接合型太陽電池のトップセル発電層として有望なCu(In,Ga)Se2(CIGS)系に着目し、(1)高真空における固液界面を介した結晶制御法の開発による高品質な1.65eV禁制帯幅のCIGS薄膜材料を創出する。また、(2)豊富な材料群で既に開発されている1.1 eV禁制帯幅のボトムセルとの自在な多接合化に向けて、ガラス基板上で作製したCIGS太陽電池のCIGS/Mo界面の密着性制御による「素子剥離法」を確立し、ボトムセルとの「再接合」を可能とする新奇な多接合化技術を開拓する。

Outline of Final Research Achievements

A crystal growth technique was developed for the fabrication of the high-quality Cu(In,Ga)Se2(CIGSe) top-sell absorber. The flux growth through the Cu-Se liquid phase under Cu-rich conditions led to an increase in the grain size of CIGSe. A supply of the Se element during the growth of the CIGSe with the Cu(2-x)Se precursor resulted in the formation of a uniform Cu-deficient layer on the CIGSe surface. To avoid thermal degradation of the bottom-cell due to deposition temperatures of approximately 600°C, a peeling-off technique using MoSe2 layered material was developed. A semitransparent CIGSe top-cell was successfully fabricated.

Academic Significance and Societal Importance of the Research Achievements
