Eco Factor: Triple-junction solar cell with the world’s highest energy conversion efficiency.
Sharp has been trying to better its solar panels to make them feasible for a wide range of application areas. The company has recently announced a breakthrough technology with which it has achieved a record conversion efficiency of 35.8%.
The triple-junction compound solar cell utilizes photo-absorption layers made from compounds consisting of two or more elements such as indium and gallium. To boost the efficiency of triple-junction compound solar cells, it is important to improve the “crystallinity” in each photo-absorption layer.
Sharp has now succeeded in forming an InGaAs layer with high crystallinity by using its unique technology for forming layers, resulting in the formation of layers that minimized waste and hitting a record conversion efficiency of 35.8%.
