Quantum Dots for Energy Efficiency

Quantum Dots for Energy Efficiency

Rising energy demands worldwide are calling for both increased energy supply and improved efficiency in usage.

 

Researchers within the Semiconductor Physics & Nanostructures Research Group at Lancaster University are addressing these two areas through the atomic-scale engineering of materials.  The work being done by Professor Tony Krier and his team is being applied to improve the efficiency of solar cells by implementing novel semiconductor material containing Quantum Dots.  This is achieved by introducing several layers of Quantum Dots into the active region of a solar cell, to extend the spectral response of the cell, so that more of the sun's radiation is absorbed and converted into electricity.
