ABSTRACT
Solar PV technology is demonstrating its application all over the globe, as a green and renewable energy source. With the research efforts, the power generation efficiency has increased a lot from a mere 6% in the beginning. The technology has enormous scope for increasing its efficiency with integration and applications of various methods. The introduction of new generation solar cells has widened this scope. The second, third, and fourth generation PV cells have properties which make them viable for commercial use. The objective of this review is to show the current state of art of PV technology, material, manufacturing techniques and their efficiency and also highlights different studies done globally in this area of research.
