Outline of Final Research Achievements

This study focuses on the fabrication of solar cells based on wide gap CuGaS2 (CGS) thin films, and investigated its effectiveness as an impurity band material. Therefore, first of all, we were able to demonstrate the solar cell operation. In particular, the main key is the result of improving the solar cell characteristics by adding Zn to the CdS buffer layer.
Then, in order to evaluate the physical properties of the impurity band characteristics toward realizing an intermediate band solar cell material, the evaluation of the Cr-added CGS thin film was proceeded. In PL emission, it seems to be a great achievement that 1.5eV impurity band emission could be confirmed in parallel with 2.43eV bandgap emission.
These results are expected to greatly promote the operational demonstration of impurity band type solar cells based on wide-gap CGS materials.

Academic Significance and Societal Importance of the Research Achievements

中間バンド型太陽電池において、中間バンドの母体となるワイドギャップの半導体材料開発が必須である。一方、高品質結晶性薄膜成膜として真空蒸着技術が求められるがワイドギャップ半導体の融点及び静電容量が高く、従来の真空蒸着技術でその成膜が困難である。本案件で進めた同時多元スパッタ成膜と並行して低融点物質加熱システムを開発したことで、蒸気圧の高い硫黄ガスの制御が可能となり、良質な結晶母体及び高品質な界面物性を得ることができた。
本研究では、新しい原理に基づく、枯渇元素を含まない環境負荷の低い太陽電池材料が得られたことが資源制約をいかに打破してイノベーションに繋げるかの課題克服に貢献できたと思われる。
