Abstract

The invention discloses a solar energy light condensation mechanism, comprising a light condensation box and a light condensation module. The light condensation module comprises plane filter bases, reflector fixing bases, plane filter incline adjusting rods and plane filter frames. The plane filter frames are fixedly connected with plane filter incline adjusting supports on the plane filter incline adjusting rods through frame support vertical posts. Plane filter rotation adjusting rods for adjusting the rotation angles of plane filters are mounted on the plane filter frames. Silicon cells are correspondingly arranged above the plane filters. Triple-junction solar cells are arranged right below the plane filters. The silicon cells are fixed on a protection cover through silicon cell supports. Parabolic cylinder reflectors for condensing incident light are mounted on the reflector fixing bases. According to the mechanism, bandpass filtering is carried out on the wavelength of sunlight by utilization of the plane filters, so that the currents of the sub-cells of the triple-junction solar cells match each other; and the energy is collected through the silicon cells, and the utilization rate of the whole mechanism for the solar energy is improved.

Description

technical field [0001] The invention relates to the field of solar power generation equipment, in particular to a solar light concentrating mechanism. Background technique [0002] At present, commercial solar cells have developed to the third generation, from the first generation of crystalline silicon cells to the second generation of thin film cells, and then to the current third generation of multi-junction cells, the conversion efficiency of the cells has also changed from ~22% of that of crystalline silicon. %, ~15% for thin films to ~40% for multi-junctions. Concentrating photovoltaics use concentrating optical elements with a much lower cost than batteries to converge incident sunlight to solar cells, reducing the area used for photovoltaic materials and reducing the cost of photovoltaic power generation per kilowatt-hour. [0003] Due to the concentration of light, the energy received by the unit area of ​​the battery is greatly increased, which will generate a ver...
