Conveniently rotated vertical solar cell column

Abstract

The invention discloses a conveniently rotated vertical solar cell column. The conveniently rotated vertical solar cell column comprises a fixed base and a rotating bearing, wherein a rotating cover plate is arranged on the rotating bearing; a barrel pointing to the upper part is arranged on the rotating cover plate; a plurality of solar cell pieces are axially arranged on the excircle of the barrel for covering; each solar cell piece comprises a first electrode rod and a second electrode rod extending to the interior of the rotating cover plate; first electrode annular fixed seats corresponding to the first electrode rods are arranged on the fixed base; and second electrode annular fixed seats corresponding to the second electrode rods are arranged on the fixed base. Through the manner, the conveniently rotated vertical solar cell column disclosed by the invention is of a vertical structure, is small in floor space and convenient to rotate, and avoids the problem of overheating caused by continuous high-strength working of a single solar cell piece; and the first electrode rods and the second electrode rods are connected through first conducting rings and second conducting rings respectively.

Description

technical field [0001] The invention relates to the field of solar cells, in particular to a conveniently rotatable vertical solar cell column. 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 a solar cell, and the single working surface is easy to accumulate heat and damage, and the ver...

[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 solar cells are mostly flat structures, which occupy a large area, which is not conducive to multiple solar cells. The dense placement of solar cells, and the single working surface, is easy to accumulate heat and damage, and the vertical rotating structure has the problem of electrode connection, which needs to be improved.
