Abstract

Absorption of light, generation of charges carriers (electrons and holes), the separation of the electrons from holes and their transport to electrodes, are the sequence of events of solar energy conversion.

Different nanostructures have been employed in the structure of solar cells, to improve its efficiency with simple manufacturing process and low cost.

Zero dimensional nanostructures have gained interest due to their unique properties especially tuning their band gap based on their size and multiple exciton generation.

One  dimensional nanostructures are promising for PV devices due to several advantages.  They offer large surface area, high optical absorption across a broad spectrum, direct path for charge transport and high charge collection efficiency. Graphene has recently emerged as an alternative to ITO substrate as an electrode in solar cells structure. With its remarkable electrical, physical and chemical properties, and high degree of flexibility and transparency; it is considered as an ideal candidate for flexible 3^rd generation solar cells, the graphene solar cells an eco- green technology is getting to the same level of ITO based solar cells.

This presentation is about presenting a flexible quantum dots sensitized solar with graphene electrode .
