Abstract- Currently, solar energy is promising the primary source of renewable energy that has a great potential to generate power for an extremely low operating cost when compared to already existing power generation technologies. Increasing the efficiency of solar cells is a major goal and the prominent factor in photovoltaic system research. Current triple junction solar cells reach 30% and the next generation will bring 35% in 5 years to peak at 40%. These cells are used in space environment and in terrestrial systems. Nowadays highly efficient multi-junction solar cells are employed in many applications. In regard to terrestrial industrial applications, induction motor is being fed from the multi-junction photovoltaic system using a boost converter and three phase inverter for variable–speed applications. Another application for multi-junction solar cells is the use in space vehicles and satellites. Indeed, solar PV array are the only non-nuclear means that enable space systems to be fed continuously. In this research work, we had simulated, investigated and correlated the performance of multi-junctions in terms of efficiency, fill factor, and other electrical parameters. Subsequently, the influence of temperature and irradiation on the electrical parameters of solar cells was investigated to guarantee a certain level of reliability and performance of these. Then, we had made an efficiency comparison between a various solar cells to determine the best choice which will bring a good performance to be used in the design of solar array of our multi-junctions photovoltaic systems. Finally, an experimental test bench of low-cost characterization system for photovoltaic solar cells array was designed using Arduino MEGA2560 board to automate the characterization performance.
