The efficiency of solar cell depends on how the different portions of the solar spectrum are converted to electric energy. The efficiency of solar cell can be increased by using multi-solar cells in tandem configuration or tandem solar cell. The device structure and material choice of tandem solar cell can affect their efficiency. Incorporating quantum well in the solar cell structure also affects their efficiency. This work proposed a new solar cell structure with efficiency 47%, which is very promising. Different materials of the cell and the embedded quantum well will help to increase the efficiency of this solar cell. The fabrication of the cell is less complicated than other promising solar cell because of single quantum well structure. Comparison with other published work also shows the improved performance of this cell.
