Solar cell capable of improving photoelectric conversion efficiency

Abstract

The invention discloses a solar cell capable of improving the photoelectric conversion efficiency. The solar cell comprises a cell panel, wherein the cell panel is fixedly arranged on a mounting plate; a slide chute is formed in one side, far away from the cell panel, of the mounting plate; a traction block is arranged in the slide chute in a sliding manner; one side of the traction block extendsto the outer side of the mounting plate and is hinged with a vertical bar; a sleeve is arranged at the outer side of the vertical bar in a sliding manner; a support plate is welded at the bottom of the sleeve; a first chain wheel is rotationally arranged at one side of the support plate and is connected with a reel in a welding manner; the bottom of the vertical bar is fixedly connected with a drawing wire; the drawing wire is wound on the reel; and a vertical stepper motor arranged on the support plate is arranged at the lower part of the first chain wheel. The solar cell is high in practicalperformance, simple in structure and convenient to operate; and horizontal and vertical angle adjustment can be carried out on the cell panel, so that the sunlight can directly irradiate the cell panel and the photoelectric conversion efficiency of the cell panel is effectively improved.

[0002] Because of energy and environmental issues, solar cells have attracted public attention. A solar cell is a power generation device that uses the photoelectric effect to obtain photoelectric power. The patent document CN106449777A provides a solar cell module with high photoelectric conversion efficiency. This structure Including solar panels, the first type of solar cell and the second type of solar cell, the first type of solar cell and the second type of solar cell have opposite polarities on the front side of the light-receiving surface. The reduction of photoelectric conversion efficiency and the cumbersome problems of series flipping, and the flexibility to increase the output power, because the sun is constantly rotating, sometimes the sunlight will not be able to directly shine on the solar panel, this structure is not convenient for the solar panel. Adjusting the tilt angle will reduce the conversion efficiency of the solar panel and affect the normal use of the solar panel. Therefore, we propose a solar cell that improves the photoelectric conversion efficiency to solve the above problems
