ABSTRACT
There has been increasing interest in the last couple of decades, in materials with nanometer-scale dimensions. ‘Quantum dots, nanowires and nanotubes’ have received special attention for their distinctive properties and intricate structures. Many nanowire-based materials are promising candidates for energy conversion devices. The quantum dots, nanowires and nanotubes have been incorporated in solar cells based on silicon and compound semiconductor thin films to advance the performance. There have been tremendous efforts in this field showing promising results indicating high potential for the fabrication of low cost high efficiency PV devices. These approaches are discussed in this chapter.
