Quantum Dot Solar Cells to Capture Broader Spectrum of Sunlight

 Quantum Dot Solar Cells to Capture Broader Spectrum of Sunlight

For the first time, researchers have created solar cells made of different-sized quantum dots, each tuned to a specific wavelength of light. By arranging these quantum dots in an ordered pattern, the scientists hope that they can one day fabricate “rainbow” solar cells, which can efficiently harvest a large part of the useful spectrum of sunlight.
