design and simulation of a highly efficient ingan/si doublejunction solar cell

A solar cell is an electronic device which not only harvests photovoltaic effect but also transforms light energy into electricity. in photovoltaic phenomenon, a pn junction is created to form an empty region.  the presented paper aims at proposing a new highly efficient ingan/si doublejunction solar cell structure. this cell is designed to be used in a real environmental situation, so only structural parameters are optimized. in the present structure, a thin layer of cds is used as the antireflector window layer. the cell is simulated using atlassilvaco software and its maximum efficiency is computed to be 37.23%. considering the supposed structure, the findings show that the efficiency of this solar cell, which is 37.32%, is so far the highest reported efficiency amongst all solar cells.
