Abstract

The invention provides a low-cost temperature reduction solving scheme. An air circulation layer is formed by a gap between a photovoltaic battery plate and a steel glass panel. Specifically, an air nozzle is mounted on the lower right side of the battery plate and connected with an air pump. One or more exhaust holes are formed in the upper left side of the battery plate. In addition, a temperature measurement automatic control circuit is designed; and when the temperature of the battery plate reaches 60 DEG C, the air pump is started to supply air for reducing the temperature so as to improve the photoelectric conversion efficiency.

Description

Improve the generating efficiency technology under a kind of solar-energy photo-voltaic cell intense light irradiation condition
Technical field:
The present invention is applied to the solar-energy photo-voltaic cell product, and the falling temperature technique low with cost, that efficient is high improves electricity conversion.
Background technology:
Solar power generation is a kind of green energy resource, relies on national support policy to develop rapidly.Because the silion cell characteristic reaches the standard optoelectronic transformation efficiency at 25 degrees centigrade, when being higher than 80 degrees centigrade, optoelectronic transformation efficiency is almost nil.And in the silicon solar cell application process, because the dark colour of silicon face is easy to make battery to be in the condition of high temperature under the intense light irradiation condition, cause generating efficiency to reduce.
We are contained in photovoltaic cell on the electric automobile in practice, and under the high illumination condition, the charging current when starting is much higher than inactive state, thereby find that conversion has very strong influence to photoelectricity in cooling.
Because manufacturing enterprise, solar-energy photo-voltaic cell do not understand power generation needs, only by product standard production.And electricity power enterprise is to the trust of photovoltaic product, and the battery component of costliness is not proposed recommendation on improvement.The method of Ceng Youyong trickle cooling, but cost height, use in the area that is not suitable for lack of water.The employing present technique can improve the generating efficiency under the high illumination condition with lower cost.
Be to promote the green energy resource industry development, the environment of preserving our planet is ready to sell at a low price patent of the present invention.
Summary of the invention:
Utilize the slit between photovoltaic battery panel and the toughened glass panel, make the circulation of air layer.Specifically an air nozzle is installed in (or left side) below on the cell panel right side, connects the low pressure air pump.One or several steam vent is opened in (or right) top on a cell panel left side.Other designs the automatic temperature measurement control circuit, and automatic booster air pump air feed makes air-flow pass through the slit when the cell panel temperature reaches 60 degrees centigrade, blows over the silicon cell surface, discharges from the hole gas of another side, reduces temperature, improves electricity conversion.
Description of drawings:
Fig. 1 solar energy photovoltaic panel Fig. 2 photovoltaic panel cross section enlarged drawing
Embodiment:
As accompanying drawing: be installed into valve 4 in the lower right, be fixed on the aluminum alloy frame 3, pad rubber washer 7 below is with anti-gas-leak.The automatic temperature measurement control system is installed separately.When silicon cell reaches 60 when spending, booster air pump, to suction nozzle 4 input low-pressure air currents, air-flow is discharged from the upper left side, takes away unnecessary heat.
Import and export will be carried out the structure that prevents that aqueous vapor from entering.
