Absorbed layer CIGS thin-film is the core of CIGS solar cell, and the preparation method of absorbed layer is as selenizing method after polynary steaming method altogether and magnetron sputtering.Although these evaporating deposition techniques can prepare the high CIGS hull cell of conversion efficiency, the vacuum equipment of precision needs very large equipment investment, and the production cycle is long, and this makes the production cost of battery higher.Device for selenization is called selenizing stove, and existing selenizing stove is all close heat-treatment furnace based on glass substrate CIGS solar cell batch-type.In this scenario, several pieces surface depositions have the substrate delamination of precursor film to be placed in selenizing stove, are then heated to 450 ~ 600 DEG C under lower than 1 DEG C/s heating rate and react between 30 minutes to a few hours in H2Se or Se atmosphere.The problem that this batch-type closes selenizing stove is, every batch all will through vacuumizing, heating, be incubated, temperature-fall period, the cycle is long, energy consumption large, reduces production cost unfavorable for enhancing productivity.
Also disclose a kind of selenizing stove at present, if notification number is the Chinese patent of CN102185024B, furnace chamber is divided into four sections and carries out selenizing to substrate by it, but due to its mode adopting middle air inlet, two ends exhaust, makes the exhaust of conversion zone thorough not; And it adopts interlayer to add the mode of aperture to substrate selenizing, sprays even not.
Summary of the invention
For above-mentioned technical problem, the invention provides a kind of spraying evenly, exhaust CIGS solar battery obsorbing layer selenizing stove more thoroughly.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of selenizing stove preparing CIGS solar battery obsorbing layer, comprise the burner hearth of selenizing CIGS solar cell substrate and transmit the conveyer belt of substrate through these burner hearth two ends, the whole outer wall of burner hearth is coated with temperature control heating device, described burner hearth is divided into spraying area, reaction zone and air inlet area by four successively to upper and lower baffle plate, leave the gap for conveying Tape movement between upper and lower baffle plate, the injection apparatus of the described substrate injection selenium steam to movement is installed in described spraying area; Be provided with inert gas air admission hole in burner hearth reaction zone one end, the burner hearth other end is provided with steam vent, between described spraying area and reaction zone, is equipped with gas via-hole between reaction zone and air inlet area.
Further, described air admission hole, through hole, steam vent are crisscross arranged on the upper and lower baffle plate of correspondence.
As preferably, described air admission hole is arranged on the lower baffle plate of one end described in burner hearth.
As preferably, on the downside of described spraying area, be provided with the air-permeable mattress of support belt.
As preferably, described injection apparatus comprises several nozzle, and several nozzle is scattered in row vertical with the conveyer belt direction of motion.
As preferably, described injection apparatus comprises a selenium steam pipe, and at least one row's spray-hole opened by this selenium steam pipe, and each row's spray-hole is vertical with the conveyer belt direction of motion.
The present invention compared with prior art tool has the following advantages:
1, the present invention adopts the substrate at the uniform velocity movement to spray the mode of selenium steam, and not only spraying evenly, be conducive to improving selenizing effect, and efficiency is high.
2, adopt the air inlet of burner hearth one end, the mode of other end exhaust, and airflow direction is contrary with direction of substrate motion, carries portion of air and enter reaction zone when not only avoiding conveyer belt to move, and the exhaust of reaction zone is very thorough.
3, by by air admission hole, through hole, steam vent is upper and lower is crisscross arranged, and makes the exhaust of reaction zone more thorough.
Accompanying drawing explanation
Fig. 1 is the structural representation of optimal way of the present invention;
Fig. 2 is inlet zone cross section of the present invention enlarged diagram.
Embodiment
The present invention is introduced in detail below in conjunction with accompanying drawing:
Fig. 1 illustrates selenizing stove of the present invention, it comprises the burner hearth 1 of selenizing CIGS solar cell substrate and transmits the conveyer belt 3 of substrate 2 through these burner hearth two ends, the whole outer wall of burner hearth is coated with temperature control heating device 4, thus ensures that spraying area, reaction zone are consistent with the temperature of air inlet area; Described burner hearth is divided into spraying area 5, reaction zone 6 and air inlet area 7 by four successively to upper and lower baffle plate 11,12, the gap for conveying Tape movement is left between upper and lower baffle plate, be provided with the injection apparatus 8 of the described substrate injection selenium steam to movement in described spraying area, wherein injection apparatus is communicated with the device producing selenium steam.Substrate uniform motion should be ensured in implementation process, and control the constant flow of injection apparatus, be conducive to improving absorbed layer selenizing quality; On the substrate of uniform motion, spray quantitative selenium steam due to adopting, therefore, spray very even.After selenium steam has sprayed, substrate is delivered to reaction zone completely by conveyer belt and reacts.
In order to ensure selenizing effect, should by the air emptying of reaction zone, therefore, the present invention is provided with inert gas air admission hole 71 in burner hearth reaction zone one end, the burner hearth other end is provided with steam vent 51, be equipped with gas via-hole 61 between described spraying area and reaction zone, between reaction zone and air inlet area, make airflow direction contrary with the conveyer belt direction of motion like this, have utilization thoroughly to discharge air.Before ejecting, should carry inert gas by air admission hole to air inlet area, inert gas enters reaction zone and inlet zone successively by the gap between upper lower baffle plate and through hole, thus is discharged from steam vent by air.Because reaction zone is arranged between inlet zone and air inlet area, even if there is gap, also can ensure the air of emptying reaction zone, thus improve the quality of reaction zone selenizing.
In implementation process, described air admission hole, through hole, steam vent are crisscross arranged on the upper and lower baffle plate of correspondence; Like this for each district, between air inlet and exhaust outlet, there is difference in height, be conducive to, by the air emptying in region, can not dead angle being left.Further, described air admission hole is arranged on the lower baffle plate of one end described in burner hearth, owing to adopting the mode be crisscross arranged, therefore on the lower baffle plate of spraying area, described through hole is provided with, inert gas is made to move from bottom to top in spraying area like this, not only can improve exhaust effect, and substrate back can be prevented by selenium steam corrosion.During in order to ensure to spray, conveyer belt is indeformable, and can arrange air-permeable mattress 9 support belt on the downside of described spraying area, air-permeable mattress can not affect gas flow, as the poroid pad etc. adopting temperature-resistant material to make.
In order to improve jeting effect, injection apparatus 8 of the present invention comprises several nozzle 81, and the quantity of nozzle is selected according to the reasonable wide of substrate, but several nozzle must be made to be scattered in row vertical with the conveyer belt direction of motion, can make to spray more even like this, jeting effect is higher.Alternatively, as Fig. 2, injection apparatus 8 can comprise row's selenium steam pipe 82, and at least one spray-hole 83 opened by this selenium steam pipe, and each row's spray-hole is vertical with the conveyer belt direction of motion, and this structure is simpler, and cost is lower.
Above-mentioned execution mode is used for illustrative purposes only, and be not limitation of the present invention, the those of ordinary skill of relevant technical field, without departing from the spirit and scope of the present invention, can also make various change and modification, therefore all equivalent technical schemes also should belong to category of the present invention.
