Semi-conducting nanomaterials, also known as quantum dots, show promising potential for the fabrication of inexpensive, yet efficient solar cells. This is due to characteristics of
these materials which; allow for their band gaps to be tuned for more efficient photon capture, multiexciton generation which allows for several electrons to be generated from one photon, and, the
phenomenon of slower carrier cooling in nanostructures. This paper discusses the theory behind those characteristics how these properties were manipulated to make quantum dots that can be used in
the fabrication of low cost, high efficiency solar cells.
