Abstract

The invention discloses a solar photovoltaic cell with a micro-fluidic structure, aiming at overcoming the problem that the prior solar photovoltaic cell has no better radiating effect. The solar photovoltaic cell comprises an upper cover plate, a solar cell panel, a lower cover plate and a working medium. The solar cell panel is arranged in the lower cover plate; the upper cover plate covers thelower cover plate; the upper cover plate and the lower cover plate are adhered by adhesive in a sealing way; an upper fluid channel is formed between the lower surface of the upper cover plate and the upper surface of the solar cell panel; a main lower fluid channel is formed between the lower surface of the solar cell panel and the bottom surface of the slot of the lower cover plate; branched lower fluid channels are arranged in the radiating fins at the bottom of the lower cover plate; the main lower fluid channel is communicated with the lower fluid channels; the upper fluid channel is communicated with the main lower fluid channel; the left end of the solar photovoltaic cell is provided with a working medium inlet, and the right end is provided with a working medium outlet; both the working medium inlet and the working medium outlet are communicated with the main lower fluid channel and the upper fluid channel; and the working medium is filled between the upper cover plate and thelower cover plate which are adhered in a sealing way.

Description

technical field [0001] The present invention relates to a solar photovoltaic cell, and more particularly, the present invention relates to a solar photovoltaic cell with a microfluidic structure which adopts microfluidic technology to achieve higher photovoltaic conversion efficiency. Background technique [0002] Solar panels are made of semiconductor materials that convert the radiant energy of sunlight into direct current. Sunlight illuminates the semiconductor p-n junction to form a new hole-electron pair. Under the action of the p-n junction electric field, the holes flow from the n region to the p region, and the electrons flow from the p region to the n region. After the circuit is turned on, a current is formed. This is how photoelectric effect solar cells work. [0003] The conversion efficiency of solar panels decreases with the increase of the incident angle of sunlight and the increase of operating temperature. Therefore, reducing the incident angle of sunlight...
