High efficiency solar generator column

Abstract

The invention discloses a high efficiency solar generator column, which comprises a fixed cylinder and a first position-limit plate, the fixed cylinder is arranged in the front of the first position-limit plate, and the first position-limit plate is provided with a second position-limit plate extending outward on each of two sides. The second position-limit plate is provided with filter membrane on each inner side. The first position-limit plate is provided with light reflection layer on the surface, and the fixed cylinder is provided with several solar cells. The above-described high efficiency solar generator column with the fixed cylinder standing on the ground takes small covering area, enhances light intensity of solar cells by reflection of sunlight through light reflection layer. The filter membrane allows coming sunlight irradiate solar cells, and the sunlight which reflects from the solar cells to the filter membrane reflects back without penetration, then enhances the light intensity achieved by the solar cells on the two sides of the fixed cylinder.

Description

technical field [0001] The invention relates to the field of solar cells, in particular to a solar power generation column with high power generation efficiency. Background technique [0002] A solar cell is a device that directly converts light energy into electrical energy through the photoelectric effect or photochemical effect. As long as the solar cell is illuminated by light, it can output voltage and current instantly. [0003] In fact, the solar energy density directly reaching the ground is very low, and its peak value does not exceed lkW / m 2 At present, the average efficiency of monocrystalline and polycrystalline silicon solar cells produced in large quantities on the market is about 15%. Therefore, the utilization rate of light energy is still very low, and most solar cells are flat-plate structures, which occupy a large area, which is not conducive to multi- The intensive placement of solar cells needs to be improved.
