The combination of quantum dots and solar cells can give solar cells new performance. Quantum dots can make solar cells absorb light of a specific wavelength by changing the size of semiconductor quantum dots, that is, small quantum dots absorb short-wavelength light, and a large number of sub-dots absorb long-wavelength light. This makes it widely used in solar cells and can greatly improve the ...
