Study on utility of nano-semiconductors in solar cells

Abstract

Nano-semiconductors have many advantages making it an appealing choice for many applications. One of the most important nano-semiconductors is quantum dots which have attracted interests due to their unique size-dependent effect and their multiple exciton generation (MEG) effect.

The study is divided into three chapters:

Chapter one: Introduction and literature review: This Chapter includes a general introduction on semiconductor nanocrystals and quantum dots classification and its advantages which candidate it for using in many applications which one of them is solar energy application. A literature review on several types of quantum dots and their application in solar cells. Recent references related to research has been used.

Chapter two: This chapter deals with the two different experimental techniques that have been employed to prepare low cost environmental green water-soluble quantum dots such as: CdSe, CdTe, CdZnSe, CdZnTe, CdSeTe, CdZnSeTe and CuZnS
