First-principles studies of defects in colloidal nanocrystals

Solar energy is one of the few renewable, low-carbon sources with both the maturity and accessibility to meet the ever-increasing global demand for energy. There are also accounting for an increasing percentage of our energy output due to increased adoption in both industrial and residential areas. Wafer based silicon photovolatics (PV) technology has dominated the solar market, whereby its price has increased significantly over the last decades. In order to fully capture the solar energy from the sun and extend the flexibility of PV technology, there is a need for constant innovation for new materials. Currently, there is a class pf emerging PV technologies that offer the potential of increased scalability, flexibility and lower prices. They include hybrid organic-inorganic lead halide perovskite PV, organic PV and colloidal quantum dot (CQD) PV. Colloidal quantum dots are semiconducting nanocrystals that exhibit size tunable electronic and optical properties.
