Abstract

The utility model discloses a solar cell panel with a self-cleaning function. The solar cell panel is characterized in that the solar cell panel comprises a substrate for supporting a solar cell main body, a bottom electrode layer, a semiconductor layer, an upper electrode layer and a piece of packaging glass, wherein the substrate, the bottom electrode layer, the semiconductor layer, the upper electrode layer and the packaging glass are successively and closely cooperated. A photocatalytic film doped with nanoscale titanium dioxide is pasted on the packaging glass; and a hydroxide radical cleaning layer containing hydroxide radical raw materials is coated on the photocatalytic film surface. Because the photocatalytic film is doped with nanoscale titanium dioxide and the hydroxide radical cleaning layer is coated on the photocatalytic film surface, the photocatalytic film has good hydrophilicity and the catalytic activity and the oxidbillity of the film are improved, so that the film can absorb water under the circumstances that there is no water and the dust and the dirt can be separated from the cell panel under the effects of oxidation and catalyzing. Therefore, a self-cleaning objective of the cell panel can be achieved; the cell panel conversion performance and the conversion stability can be improved; and the service life of the cell panel is also enhanced.

Description

A kind of solar panel that the self-cleaning function is arranged

Technical field

The utility model relates to a kind of solar panel that the self-cleaning function is arranged.

Background technology

Solar panel mainly be place outdoor, the device of conversion luminous energy, but place for a long time outdoor, a lot of dusts and dirt will be assembled in the surface of cell panel, to affect the light percent of pass like this, to affect the solar energy conversion efficiency, cause the stability of solar panel to reduce, so that solar panel conversion load increases, the while is under high load capacity, reduce its useful life, therefore we must be improved for such situation, and some designers are square in addition on cell panel to have installed the glass of being convenient to clean, but causes like this cost to strengthen, therefore we need to be improved present situation, and more outstanding solution is provided.

The utility model content

The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of solar panel that the self-cleaning function is arranged is provided.

Solve the problems of the technologies described above for real, the utility model adopts following technical scheme:

A kind of solar panel that the self-cleaning function is arranged, structure is substrate, bottom electrode layer, semiconductor layer, upper electrode layer and the packaged glass of support solar battery main body, described substrate, bottom electrode layer, semiconductor layer, upper electrode layer and packaged glass closely cooperate successively, post the photocatalysis film that has mixed Nano titanium dioxide at packaged glass, described photocatalysis film surface scribbles the hydroxyl clean layer of hydroxyl raw material.

Further, described upper electrode layer and bottom electrode layer form the extraction electrode pair of solar cell, and described extraction electrode is to comprising positive pole and negative pole.

The utility model beneficial effect is: described photocatalysis film mixes the nano level titanium dioxide that has, the photocatalysis film surface scribbles the hydroxyl clean layer simultaneously, make film have very strong hydrophily, catalytic activity and the oxidizability of film have been improved simultaneously, make film when having water, can not absorb water, under the effect of oxidation and catalysis, make dust and dirt break away from cell panel, reach the purpose of self-cleaning cell panel, the cleaning that keeps cell panel, improve the stability of cell panel conversion performance and conversion, improved simultaneously cell panel useful life.

Fig. 1 is the utility model structure cutaway view.

Embodiment

In order better to understand the utility model technology contents, the below provides specific embodiment, and by reference to the accompanying drawings the utility model is further specified.

The present embodiment, with reference to Fig. 1, a kind of solar panel that the self-cleaning function is arranged, its structure is the substrate 1 of support solar battery main body, bottom electrode layer 2, semiconductor layer 3,4 layers of top electrodes and packaged glass 5, described substrate 1, bottom electrode layer 2, semiconductor layer 3, upper electrode layer 4 and packaged glass 5 closely cooperate successively, post the photocatalysis film 6 that has mixed Nano titanium dioxide at packaged glass 5, described photocatalysis film 6 surfaces scribble the hydroxyl clean layer 7 of hydroxyl raw material, described upper electrode layer 4 and bottom electrode layer 2 forms the extraction electrode pair of solar cells, and described extraction electrode is to comprising positive pole and negative pole.

Described photocatalysis film mixes the nano level titanium dioxide that has, the photocatalysis film surface scribbles the hydroxyl clean layer simultaneously, make photocatalysis film have very strong hydrophily, improved simultaneously catalytic activity and the oxidizability of film, made film when having water, can not absorb water, under the effect of oxidation and catalysis, made dust and dirt break away from cell panel, reach the purpose of self-cleaning cell panel, the cleaning that keeps cell panel improves the stability of cell panel conversion performance and conversion, improves useful life.

The above only is to preferred embodiment of the present utility model; be not that scope of the present utility model is limited; therefore under the prerequisite that does not break away from the utility model design spirit; the equivalence that the common engineers and technicians in this area do structure described in the utility model, feature and principle changes or decorates, and all should fall in the protection range that the utility model applies for a patent.
