Abstract

The invention relates to a concentrating solar power photovoltaic conversion device or photothermal conversion device. The concentrating solar power photovoltaic conversion device or photothermal conversion device comprises a solar power concentrating device, a quantum dot material, a resonant cavity and a photovoltaic conversion battery or a photothermal conversion battery. Sunlight is converged into a secondary reflector by the solar power concentrating device, concentrated light of solar power is projected on the quantum dot material and in the resonant cavity by the secondary reflector, the quantum dot material absorbs wide solar spectra and emits narrow spectra which can be absorbed by the photovoltaic conversion battery or narrow spectra which can be absorbed by the photothermal conversion battery, and the light emitted by the quantum dot material lights on the photovoltaic conversion battery to conduct photovoltaic conversion or lights on the photothermal conversion battery to conduct photothermal conversion.

Description

technology field; [0001] The invention relates to a concentrated solar photoelectric conversion device or a photothermal conversion device. Background technique: [0002] Solar direct pumping laser is a promising way to utilize solar energy. It uses solar radiant energy as a pumping source to convert broadband, incoherent sunlight into narrow-band, coherent laser light. [0003] Quantum dots, also known as nanocrystals, are nanoparticles composed of II-VI or III-V elements. The particle size of quantum dots is generally between 1 and 10 nm. Since electrons and holes are quantum-confined, the continuous energy band structure becomes a discrete energy level structure with molecular characteristics, and can emit fluorescence after being excited. [0004] Quantum dots have a wide excitation spectrum and a narrow emission spectrum. The emission spectrum of quantum dots can be controlled by changing the size of quantum dots. By changing the size and chemical composition of quantu...
