Information
Abstract
The present invention relates to an intermediate band solar cell. More specifically, the present invention is directed to a solar cell which incorporates a plurality of colloidal quantum dots and metal nanoparticles embedded in a host semiconductor. The quantum dots are provided with a shell which enables the absorption of photons with energies within an extended range as compared to conventional solar cells, thus increasing the efficiency of the solar cell. The metal nanoparticles are efficient optical antennas at their surface plasmon resonance, attracting the light from their surroundings and focusing it in their near-field, thereby forming a light trapping structure in the cell that increases the absorption of light in the intermediate band and, thus, further improves the conversion efficiency of the solar cell.
