Abstract
Quantum dots have offered an attractive option for photovoltaic. Multi junction solar cells made from quantum dots have been able to achieve around 7% conversion efficiency in the lab. While figures like this may not seem too impressive when compared to silicon solar cells, their promised theoretical conversion efficiency limit is an eye-popping 45%. This is possible because when a single photon is absorbed by a quantum dot, it produces more than one bound electron-hole pair, or exaction, thereby doubling normal conversion efficiency numbers seen in single-junction silicon cells. In this paper discuses about solar cell quantum dots and will be reviewed advantage and disadvantage Quantum dot solar cell.
