Highly efficient Multi-Junction Solar Cells Performance Improvement for AC Induction Motor Control Using the dsPIC30F Microcontroller

Solar energy is an abundant renewable source which is expected to play an increasing role in terrestrial and space systems future infrastructure for distributed power generation. Improving of solar performance and efficiency is a key goal of research and the prominent factor in photovoltaic systems which make PV technologies cost-competitive with conventional sources of energy. Multi-junction solar cells are the most efficient technology for generation of electricity from solar irradiation. It's estimated that these cells have an incredible efficiency for more than 40%. They have the advantage of improved performance. Highly efficient multi-junction solar cells find their use in many applications. In regard to terrestrial industrial applications, AC electrics motors are being fed from the multi-junction photovoltaic systems when exposed to high light concentrations using a boost converter and three phase inverter for variable speed AC induction motor drives based on full digital control. Another application for multi-junction solar cells is the use in space vehicles and satellites under low light concentrations. The aim of this research work was modeled and simulated the multi-junction solar cells to improve their performance in terms of efficiency for further exploration in future photovoltaic power generation systems and implemented a variable speed control of an AC Induction Motor using the dsPIC30F Microcontroller for high performance industrial applications.
