ABSTRACT

Depleting energy resources and environmental conditions have prompted the use of greener energy resources. Solar cells have been utilized since decades to overcome this worldwide problem. We are now in third generation solar cells with the use of Dye Sensitized Solar Cells (DSSC?s). This new technology has utilized nano semiconductors and dye stuff varying from synthetic origin to naturally available ones from various plant sources. The major limitation of such DSSC?s is its longevity. As soon as the electrolytes dry up the efficiency of these cells reduces. This chapter tries to sum up few important inventions in modern DSSC?s that utilize bio polymer composites to embed both semiconductor and dye material. Such an arrangement has proven to be highly efficient, durable and greener.
