Sharp développe une Cellule photovoltaïque efficace à 35.8%
Sharp Corporation vient de sortir une nouvelle cellule photovoltaïque annoncée comme la plus efficace en matière de conversion. En effet, celle-ci, grâce à une triple-jonction, serait capable de transformer l’énergie à hauteur de 35.8%.
Contrairement aux cellules solaires à base de silicium, soit les plus communes, ces nouvelles cellules utilisent des couches de photo-absorption composées à partir d’un ou deux éléments comme le Gallium ou l’indium. En raison de leur grande efficacité en matière de conversion, ces cellules combinées sont principalement utilisées sur des satellites.

Sharp Corporation has achieved the world’s highest solar cell conversion efficiency of 35.8% using a triple-junction compound solar cell.
Unlike silicon-based solar cells, the most common type of solar cell in use today, the compound solar cell utilizes photo-absorption layers made from compounds consisting of two or more elements such as indium and gallium. Due to their high conversion efficiency, compound solar cells are used mainly on space satellites. Since 2000, Sharp has been advancing research and development on a triple-junction compound solar cell that achieves high conversion efficiency by stacking three photo-absorption layers.
To boost the efficiency of triple-junction compound solar cells, it is important to improve the crystallinity (the regularity of the atomic arrangement) in each photo-absorption layer (the top, middle, and bottom layer). It is also crucial that the solar cell be composed of materials that can maximize the effective use of solar energy.
