Colloidal quantum dots solar cells

Solar cells fabricated from conventional bulk semiconductors such as silicon or gallium arsenide are approaching the physical limit of solar power conversion efficiency. It is believed that adapting the solar cell to the solar spectrum is one suitable approach to improving conversion efficiencies. On that basis nanostructured solar cells are attracting significant attention as promising alternatives because on that length scale the associated optoelectronic properties are improved. This chapter will explore the application of colloidal quantum dots in photovoltaic devices. Premised on historical developments their electronic structures arising from quantum confinement that results from reduced dimensionality are discussed. Optoelectronic properties are discussed based on effective methods of synthesis and how they enable control of chemical and physical properties. There is a focus on developments from fabrication methods to device physics looking at several types and performance characteristics in terms of charge carrier properties and their effect on efficiencies.
