Photovoltaics: Designs, Systems and Applications

Photovoltaics (PV) is the technology that converts light into electricity by using semiconducting materials that exhibit photovoltaic effect. Solar PV has the advantages of being environment friendly as it does not generate pollution or greenhouse gases. It shows simple scalability relative to power needs and the materials used for its construction are readily available. However, it requires direct sunlight or a sun-tracking system for optimal performance. A PV system consists of several co...
