Abstract
The utility model provides a solar cell, which comprises a junction box and a backboard, wherein silica gel is arranged between the junction box and the backboard, a cooling device is arranged between the silica gel and the junction box, and two sides of the junction box, the cooling device, the silica gel and the backboard are provided with drying units. The solar cell can effectively absorb the water vapor from the outside through the drying units on the two sides, and can better protect the reliability and capacity of the solar cell; and the working temperature of the junction box can be well controlled by the cooling device arranged inside, and the service life of the solar cell is greatly prolonged.
Description
Technical field
The utility model relates to a kind of solar cell.
Background technology
Along with the concern of the mankind to environmental protection, solar energy receives increasing the concern and attention as a kind of green energy resource, has become one of main energy at Countries solar energies such as Germany.Solar cell is a kind of opto-electronic conversion effect of utilizing, and sunlight is converted to the device of electric energy, is a kind of free of contamination clear energy sources.The complete solar cell template of one cover mainly is comprised of terminal box and backboard, adopts silica gel to be connected between terminal box and the backboard.
Yet the employed encapsulant moisture resistance of existing solar cell template is relatively poor, can't resist for a long time moisture, so that aqueous vapor can enter from the edge of solar cell template the solar cell template, so that the capacitance of solar cell and reliability decrease.
Also have, in transfer process, can produce a large amount of heats at a kind of solar cell, when heat is too high, affect easily the useful life of solar cell.
The utility model content
The technical problems to be solved in the utility model provides a kind of simple in structure, and good heat dissipation effect can effectively avoid extraneous aqueous vapor to enter the solar cell of battery.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of solar cell comprises terminal box and backboard, is provided with silica gel in the middle of described terminal box and the backboard, is provided with cooling device between described silica gel and the terminal box, and described terminal box, cooling device, silica gel and backboard both sides are provided with drying unit.
As preferred technical scheme, described drying unit is the calcium oxide drying unit.
As preferred technical scheme, described drying unit thickness is 3-5mm.
As preferred technical scheme, described cooling device is water-cooling cooling device.
The beneficial effect of the utility model solar cell is: the drying unit by both sides can effectively absorb extraneous aqueous vapor, better protects reliability and the capacitance of solar cell; The inner cooling device that arranges can well be controlled the working temperature of terminal box, the useful life that has greatly strengthened solar cell.
Description of drawings
Fig. 1 is the structural representation of the utility model solar cell.
1, terminal box; 2, silica gel; 3, backboard; 4, cooling device; 5, drying unit.
