Nuclear fusion reaction on the sun is the largest source of energy. In this paper, qualitative investigation of the numerical model of silicon germanium heterojunction solar cell is performed using MATLAB graphical user interface. The heterostructure is designed as for speculative determination of appropriate germanium mole fraction to get the maximized thin-film solar cell efficiency (ή). Other characteristics such as absorption coefficient (α), energy band gap (), reflectivity (r), open circuit voltage (), and generation rate are also considered. This user interface will reduce the complexity of solving differential equation for the analysis of silicon germanium heterojunction cell.
