Abstract
The invention discloses sintering equipment for a crystalline silicon solar cell. The sintering equipment for the crystalline silicon solar cell comprises a solar cell slice. The solar cell slice is arranged on a chained net belt; upper region heating tubes are arranged above the solar cell slice; lower region heating tubes are arranged below the solar cell slice; the upper region heating tubes and the lower region heating tubes are used for respectively and independently controlling temperature above the solar cell slice and temperature below the solar cell slice; both ends of the chained net belt are respectively provided with a drive bearing; and the chained net belt is driven by the drive bearings to enable the solar cell slice to move. According to the sintering equipment for the crystalline silicon solar cell disclosed by the invention, the heating power of the upper tubes and the heating power of the lower tubes in the high-temperature region of a sintering furnace can be respectively controlled, so that a sintering effect is optimized simultaneously, and the product quality is improved.
Description
Technical field
The invention belongs to new energy field, be specifically related to a kind of crystal-silicon solar cell sintering equipment.
Background technology
Generally speaking, traditional crystal-silicon solar cell manufacture craft comprises silver slurry and aluminium paste is printed onto respectively the silicon chip upper and lower surface, then make it to form good ohmic contact with silicon chip by the quick high-temp sintering, the mechanism that metal and silicon chip form ohmic contact is under the uniform temperature condition, metal arrives congruent melting mutually with silicon, wherein silicon chip back side aluminium silicon eutectic temperature is about 577 ℃, positive silver-colored silicon eutectic temperature is above 760 ℃, the electrode sintering of solar cell generally adopts the chain type high temperature furnace, temperature is provided by the bank light pipe thermal radiation in the body of heater, traditional sintering condition silicon chip upper and lower surface temperature is basic identical, and its shortcoming is to make the sintering effect of upper/lower electrode to arrive simultaneously optimization.
Summary of the invention
Goal of the invention: the present invention is directed to the deficiencies in the prior art, a kind of crystal-silicon solar cell sintering equipment that can control respectively up and down temperature is provided.
Technical scheme: in order to achieve the above object, the present invention specifically is achieved in that a kind of crystal-silicon solar cell sintering equipment, include solar battery sheet, solar battery sheet is placed on the chain type guipure, the top of solar battery sheet is upper district's heating fluorescent tube, the below is inferior segment heating fluorescent tube, upper district heating fluorescent tube and inferior segment heating fluorescent tube be independent control temperature mutually, control respectively the temperature of solar battery sheet above and below, the two ends of chain type guipure are equipped with drive bearing, and drive bearing drives the chain type guipure moves solar battery sheet.
Beneficial effect: the present invention is by controlling respectively the up and down heating power of fluorescent tube of sintering furnace high-temperature region, so that solar battery sheet during through the high-temperature region of sintering furnace upper and lower surface be exposed under the different temperature, thereby the sintering effect of the upper and lower surface of solar battery sheet is optimised simultaneously, has further improved the quality of product.
