Breif introduction of Cu nanopowders in Solar cell application:

A solar cell is a device that converts sunlight energy into electrical energy. The main principle is to use the photoelectric effect of semiconductors. When sunlight shines on a solar cell, the cell material absorbs incident light of a certain wavelength, and the photons are excited to generate photogenerated electron hole pairs, and then convert light energy into electrical energy. But when the sunlight shines on the solar cell, the sunlight is reflected, absorbed and transmitted. How to reduce the solar cell's reflection of sunlight, so as to obtain more photogenerated electron-hole pairs and increase its photoelectric conversion efficiency, has become an important issue to be solved.
Through the continuous efforts and research of scientific researchers, a method of using nano-metal particles to generate surface plasmon resonance with incident light on the surface of solar cells has been proposed. Surface plasmon resonance can absorb the energy of photons. When the frequency of incident light is equal or close to its oscillation frequency, the incident light will be confined near the surface plasmon, thereby increasing the absorption of light, so that the solar energy obtained by the solar cell the total amount is increased, which in turn improves its optical performance, which is the so-called surface plasmon enhanced solar cell. Metallic copper has good thermal conductivity, and the nanofluid filled with nano copper powder (Cu nanoparticle) not only has good thermal conductivity, but also shows strong absorption performance in the visible light band, which is very suitable as a circulating working fluid for direct absorption solar collectors. The preparation of nanofluids is the basis of all nanofluid problems, which mainly involves the controllable preparation of nanoparticles and the stable dispersion of nanoparticles in the base fluid.
