CFN Research Activities

Ultrathin film photovoltaic (PV) devices have received considerable interest as candidates for the low-cost alternatives of thick, wafer-based PV devices.  To overcome the low light absorption due to low optical penetration length of the ultrathin films, a new concept of a energy transfer-based hybrid PV system has been proposed where a strong light absorber is coupled with a high-mobility semiconductor layer. In operation, sunlight energy harvested by the strong light absorbing component is radiatively and nonradiatively transferred to the high-mobility semiconductor component where charge carriers are separated and transported to electrodes. We have developed an ultrathin (sub micron) c-Si PV platform based on Metal-Insulator-Semiconductor solar cell model to investigate the effects of energy transfer from the inorganic quantum dots to the Si layer.
