Summary

CHAPTER 1
SOLAR ENERGY
1.1 INTRODUCTION TO SOLAR ENERGY [PV CELL]
Non-conventional power generation is one of the fastest growing sectors. Globally, all countries are busy developing and implementing non-conventional power to bridge the electricity demand and power supply gap. Solar photovoltaic (PV) power is leading ahead of the other sources. In a solar power generation system, the PV cell plays a major role. The sun is the ultimate source of limitless solar energy in the form of light and heat. Light of the sun is directly converted into electrical energy without any inter mediate step. When the rays of the sun strike certain light-sensitive material like solar cell connected to an appropriate circuit, it exhibits a phenomenon called µphotovoltaic effect. The photovoltaic effect is the generation of an electrical current in a circuit containing a photosensitive device when the device is illuminated by visible or invisible light. In other words, light is directly converted into electricity. The photovoltaic effect can be achieved by using a variety of materials like silicon, selenium, cadmium sulphide, germanium, gallium arsenide or amorphous glass.
