Organic Solar Cell: Operating Principle, Performance Parameters, Structures and Its Advantages

Extracting sun's energy to produce electricity has proved itself to be one of the best solutions to the world energy crisis. This is solved because solar cell can provide electricity at lower cost and almost no pollution. It is very demanding and rapidly growing field for future technology to produce power at low cost. Firstly, silicon solar cells came in the markets that were working efficiently, later on organic solar cells evolved, they outshone their economical and ecological advantages. Therefore, this paper presents various aspects of solar cell for electricity production. Subsequently, it gives the brief introduction and working principle of organic solar cells (OPV). Besides this, classification of different solar cell structures is also discussed in depth because structure of OPV has significant impact on the performance. In addition to this, several other recent advancements are also presented that shows how materials and structures make a difference on the efficiency of organic solar cells.
