According to the invention, not only the appearance of the battery is ensured, but also the stability of the electrical properties is guaranteed, and beside, the method is simple in operation and low in cost, has a good processing effect, and is suitable for processing vulcanizing battery slices in batches.
Description
Technical field
The present invention relates to a kind of electrode sulfurizing treatment method of crystal silicon solar energy battery, belong to the crystal silicon solar energy battery technical field.
Background technology
Solar cell is the most promising renewable New Green Energy source technology in the world today, and crystal silicon solar energy battery is main product wherein.In crystal silicon solar energy battery manufacturing process, starch and fire the electrode that is solidificated in battery two sides formation conduction by silk screen printing silver.The cell piece electrode that just has been cured presents silvery white, conducts electricity and welds good.
Will pass through component package after crystal silicon solar energy battery completes, this process has the time of some months.In this section period, make cell piece electrode and air Long contact time will cause silver sulfuration flavescence if store improper meeting, always affect electrical property and the outward appearance of battery.Generally speaking, can cause battery time grid line variable color to affect outward appearance, the serious battery main grid line sulphide discoloration impact that causes is welded, thereby causes component power to descend.And present stage, without effective solution, being generally downgrades sells at a low price to this sulfation.
Summary of the invention
The present invention is directed to the deficiency of the problems referred to above, propose a kind ofly can guarantee the battery outward appearance, guarantee simultaneously the crystalline silicon solar battery electrode sulfurizing treatment method of electric performance stablity.
The present invention is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of crystalline silicon solar battery electrode sulfurizing treatment method, may further comprise the steps: the first step, pending crystal silicon solar energy battery is placed in the sintering furnace, temperature in the sintering furnace is arranged on 300 ℃-480 ℃, and keeps the time of setting;
Second step places crystal silicon solar energy battery in the sintering furnace, simultaneously with the Speed Setting of crystal silicon solar energy battery at the uniform velocity advancing, the crystalline silicon solar battery electrode silver sulfide decomposed and again be replaced into silver;
In the 3rd step, cooling made the battery electrode surface reduction be silvery white through normal temperature again after the decomposition of crystalline silicon solar battery electrode silver sulfide also was replaced into silver again.
Preferably: the temperature setting of described sintering furnace is set to and progressively increases progressively trend, and the initial temperature of sintering furnace is 300 ℃, and the temperature that the interior temperature of stove is heated to setting is 480 ℃.
Preferably: the time of described setting is 40s-50s, and the speed of described crystal silicon solar energy battery is 0.05m/s-0.1 m/s.
A kind of crystalline silicon solar battery electrode sulfurizing treatment method of the present invention, compared to existing technology, has following beneficial effect: because pending crystal silicon solar energy battery is placed under the hot environment, heating is decomposed the crystalline silicon solar battery electrode silver sulfide, therefore can make the silver sulfide decomposition-reduction be white silver, at this moment battery outward appearance, electrical property reduction, thereby can guarantee the battery outward appearance, and can guarantee electric performance stablity.Simultaneously the present invention, simple to operate, cost is low, treatment effect good, is fit to batch process sulfuration cell piece.
