High-Efficiency Concave and Conventional Solar Cell Integration System Using Focused Reflected Light
スポンサーリンク
概要
- 論文の詳細を見る
A concave Si single crystal prepared by mechanical polishing was successfully processed to a solar cell with a conversion efficiency of 14.7%. The concave cell could focus its reflection to a small spot, which generated further output in a conventional Si solar cell placed at the focal point. The total efficiency of this system became as high as 16.3%. The calculation results clearly show that there is room for further improvement of the total conversion efficiency by the correspondence between the small cell area and the focused spot size as well as the increase in concentration ratio.
