Abstract
In the current era, a lot of work is done on solar efficiency improvement because the world is turning toward clean energy, which is environmentally friendly and generates less global warming. More than one-junction solar cells enhance the performance of the PV modules; in this paper, four junction solar cells are exploited to convert solar power into fruitful electrical power. The InGaP/ InGaAs/GaAs/GeSi-based four-junction solar cells are produced on a micro-scale to improve the efficiency of the system by up to 43%, on the irradiated radiation intensity of the sun is near about 1000 w/m2, which is double the efficiency in comparison to the one junction solar cells. The concentration of the sun increases the output efficiency of the module decreases due to thermal heat losses. Silicon is used as a substrate for the formation of the four-junction solar cells to improve the performance of the solar module; the wafer-based bonding is used in this system, and the simulation has been done in Matlab Simulink to get a better result.
