Abstract
The invention relates to a part used in a solar cell production device, in particular to a vacuumizing groove cover device which pumps out gas generated in a groove position of the solar cell production device, enables the inner portion of a groove to be in the vacuum state, and guarantees the purpose that an reaction is good and appropriate sheet resistance is obtained. The vacuumizing groove cover device comprises a confluence shade and a vacuumizing plate which are arranged on the texturing groove. The confluence shade is composed of a trapezoid shade body and a rectangular neck portion arranged on the trapezoid shade body. The vacuumizing plate is arranged on the connection portion between the trapezoid shade body and the rectangular neck portion. The vacuumizing plate is provided with a V-shaped bent structure, wherein a plurality of air exhaust holes, are formed in the V-shaped bent structure. Externally-connected air exhaust holes are formed in an upper cover plate of the rectangular neck portion. The vacuumizing groove cover device can guarantee the consistency and the stability of the vacuum degree of all positions in the groove position, and therefore the evenness of the improvement of the sheet resistance of cells in all the positions can be achieved.
Description
Technical field
The present invention relates to the parts on a kind of manufacture of solar cells equipment, a kind of specifically the gas that produces in manufacture of solar cells equipment slots position is taken away, make to reach vacuum state in groove, guarantee that reaction is good, the sheet resistance that obtains being fit to vacuumize the groove lid arrangement.
Background technology
China pays much attention to the research and development of solar cell, and national solar power system total installation of generating capacity reached 300 megawatts by 2015 in plan." the new forms of energy development planning " of putting into effect after the Spring Festival has pointed out that the installed capacity planning of the year two thousand twenty China photovoltaic generation reaches 20GW, is 11.11 times of 1.8GW in original " regenerative resource medium-term and long-term plans ".
Crystal-silicon battery slice is along with the raising of technology and the variation of raw and auxiliary material at present, and the efficient of cell piece improves gradually, and has also formed a kind of trend on market, and everybody also wishes to utilize the powerful solar panel of high efficiency cell piece production to generate electricity.
Expect higher efficient, the researcher and in the industry engineers and technicians all make an effort from high square resistance and printing depth-width ratio, by improving original vacuum device of sobbing, guarantee that the sheet resistance that increases can reach well-proportioned degree, and then improve whole conversion efficiency.
Summary of the invention
The objective of the invention is to provide a kind of groove lid arrangement that vacuumizes, namely by this device, can guarantee consistency and the stability of each position vacuum degree in the groove position, and then reach the uniformity of the cell piece sheet resistance raising of each position.
The object of the present invention is achieved like this, this device comprises the confluxing cover and vacuumize plate that is arranged on texturing slot, the described cover that confluxes is made of trapezoidal cover body and the rectangle neck that is arranged on above trapezoidal cover body, describedly vacuumize the junction that plate is arranged on trapezoidal cover body and rectangle neck, the described strip that vacuumizes has the V-arrangement bending structure, the above has a plurality of aspirating holes, has external aspirating hole on the upper cover plate of described rectangle neck.
The present invention has the following advantages and good effect:
1, the present invention is by arranging the cover that confluxes on manufacture of solar cells equipment texturing slot position, can guarantee consistency and the stability of each position vacuum degree in the groove position, and then reaches the uniformity of the cell piece sheet resistance raising of each position.
2, because the present invention has adopted trapezoidal cover body water conservancy diversion, the plate that vacuumizes with the V-arrangement bending structure, so just can guarantee that the gas in reactive tank can be extracted in the vacuum pipe that outreaches steadily, completely, and then guarantee that the vacuum in reactive tank is in a state stably, reaches desirable purpose.

Fig. 2 be in Fig. 1 of the present invention A to projection structure figure.
Fig. 3 is the present invention's cover section structure schematic diagram that confluxes.
Fig. 4 vacuumizes plate B to the partial projection structural representation in Fig. 3 of the present invention.
Embodiment
by accompanying drawing 1, 2, 3, shown in 4: this vacuumizes the groove lid arrangement and comprises the confluxing cover 1 and vacuumize plate 2 that is arranged on texturing slot, the described cover 1 that confluxes is made of trapezoidal cover body 3 and the rectangle necks 4 that are arranged on above trapezoidal cover body 3, describedly vacuumize the junction that plate 2 is arranged on trapezoidal cover body 3 and rectangle neck 4, the described plate 2 that vacuumizes is with the V-arrangement bending structure, the above has a plurality of aspirating hole 5(and generally opens 16 aspirating holes for eight conduits), the vacuumizing plate 2 and can make the uniform and stable of bleeding of this V-arrangement bending structure, have external aspirating hole 7 on the upper cover plate 6 of described rectangle neck 4.
During use, the vacuum lead 8 of outside is connected with the external aspirating hole 7 of this device, gas in the cover 1 that confluxes can be pumped the generation negative-pressure vacuum like this, the gas that produces in the equipment reaction groove will be flowed to top rectangle neck 4 through a plurality of aspirating holes 5 that vacuumize on plate 2 along trapezoidal cover body 3, again in external aspirating hole 7 is extracted into the vacuum pipe 8 that outreaches completely, and then the assurance reactive tank in vacuum be in a state stably, reach purpose of the present invention.
