Abstract
The utility model provides a dust collecting device for a solar panel, comprising a hollow cavity. One end of the cavity is a tuyere end; the other end is connected with a vacuum generator or a compressed gas generator through a hose; the cavity is fixed on a conveying device of the solar panel so as to lead the tuyere end to face the solar panel; and the tuyere end comprises an ionic wind device and a tuyere communicated with the cavity. The dust collecting device for the solar panel can reduce and restrain the phenomena of the short circuit and the split-flow of an electrode and also can reduce the degradation of the product power generating property, the appearance quality and the stability due to the film falling off.
Description
Technical field
The utility model belongs to technical field of solar batteries, particularly a kind of device of solar panel dedusting.
Background technology
The photoelectric conversion layer of laminated silicon-base film solar cell (comprising 2 layers, 3 layers even more multi-layered) (comprises single chamber preparation and multicell technology of preparing) in preparation process, because the laser scribing and the environment of plant and chamber contamination can produce the residue and the dust granule of some, these residues and dust granule part can run through the cross section of whole photoelectric conversion layer and the surface of each tunic, residue and dust granule that part runs through whole photoelectric conversion layer will cause the electrode of back reflector and side to light to link together, and form short circuit.Residue under back electrode film and dust granule part can cause laser scribing normally to finish, thereby cause problems such as electric pole short circuit, when the laminated silicon-base film solar cell power generation, leaky can appear shunting in short circuit place, make the degradation of photoelectric conversion layer, thereby cause the performance depreciation of whole solar cell, even scrap, become one of product yield main reasons for decrease.Impurity and dust granule can cause that also product falls the power generation performance that film influences product, presentation quality, stability or the like.
A kind of invention that solves the electric pole short circuit problem is arranged at present, is after back reflector preparation, and high voltage electric field in addition on the electrode of front and back allows the high electric current of short circuit place that moment passes through that the scorification of short circuit part is disconnected.Adopting high pressure scorification method to solve the laminated silicon-base film electrode of solar battery is a kind of prosthodontic treatment technology of taking after short circuit phenomenon has occurred because of the partial short-circuit shunting, pass through high-voltage great-current, a kind of technology that diminishes, it need destroy some regional areas of laminated cell and realize this effect.Simultaneously, too high voltages can diminish solar cell.And the voltage that different shunting situations need impose is also different, so technology is difficult to control.
The general way of other is to increase environment cleanliness, and increase equipment and environment of plant frequency of maintenance increase the water matting.Increasing environment cleanliness needs very big factory's affair cost to drop into, and increase equipment and environment of plant frequency of maintenance can reduce the ordinary production time, and increasing water cleaning process needs very big equipment cost input and increase process complexity.
The utility model content
For remedying the defective of prior art, the utility model provides a kind of appearance that can reduce and suppress the electric pole short circuit distributary phenomenon, can reduce because product falls the product power generation performance that film causes presentation quality, the solar panel dust cleaning apparatus of the reduction of stability again.
Solar panel dust cleaning apparatus described in the utility model comprises a hollow cavity, and an end of this cavity is the air port end, and the other end connects a vacuum generator or Compressed Gas generator by flexible pipe; This cavity is fixed on the solar cell substrate transfer device, makes the air port end face to solar panel.Described air port end comprises ion wind device and the air port that communicates with cavity.
Above-mentioned cavity can be that the cuboid with certain radian also can be the cuboid of rule.As if adopting cuboid with certain radian, then support with slip or tourelle at the two ends that radian is arranged, slip or tourelle are fixed on the solar panel transmission device, and the rotary pulley cavity can change the angle between air port and the solar panel; At a straight end is above-mentioned air port end, and the other end connects a vacuum generator or Compressed Gas generator by flexible pipe.
If adopt the cuboid cavity of rule, then be fixed on the solar panel transmission device, and make the air port end face to solar panel by fixed connection apparatus such as screws.
In actual applications, use the arc cavity can by the rotary pulley cavity can be by a relatively large margin the change air port and the angle between the solar panel, reach best dust removing effects, and service regeulations cuboid cavity, then the cavity rotational angle is limited, and dust removing effects is lower slightly.
The power of above-mentioned vacuum generator or Compressed Gas generator can be generally between the 1Kw to 20Kw according to the adjusted size in air port.
According to the clean rank of difference, filter is installed in optional position that can above-mentioned flexible pipe, and the filtration rank of this filter can be chosen according to the actual requirements.
Solar panel dust cleaning apparatus of the present utility model can reduce and suppress the appearance of electric pole short circuit distributary phenomenon, can reduce because product falls the product power generation performance that film causes presentation quality, the reduction of stability again.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model
Fig. 2 is air port described in the utility model portion of an end office (EO) schematic diagram
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
This solar panel cavity that dust cleaning apparatus uses is one to have the rectangle cavity 1 of certain radian, and the lower end of this cavity is an air port end 3, and the other end is connected with vacuum generator by flexible pipe 2; Vacuum generator power is sized to 1KW according to air port 5.One filter 4 is installed in the body any position, and this filter is installed the different brackets filter according to the clean rank of difference.Capable of washing and the recycling of filter; Air port end 3 has ion wind device 7, and ion wind device 7 is fixed on the flat board 6 of air port end 3 centres, and both sides are air inlet 5.
Ion wind can be removed Electrostatic Absorption, and produced simultaneously wind can blow afloat impurity such as dust, and the air port 5 of being convenient to both sides siphons away impurity, produces good dust removing effects.
Above-mentioned cavity has the two ends of arc and uses tourelle to support, and this tourelle is fixed on the solar cell substrate transfer device of dust cleaning apparatus below.This cavity can rotate at tourelle upper edge radian.
Ion wind device 7 also can change the air outlet that is connected with CDA (clean dry air) into, impurity is blown afloat the air port of being convenient to both sides siphon away impurity, reaches good dust removing effects.
