Abstract
The invention discloses a surface cleaning agent and a cleaning method for a stainless steel substrate of a thin film solar cell. The cleaning agent is prepared from lauryl sodium sulfate serving as an anion surfactant, ethanol and isopropanol which serve as a cosurfactant, triethanolamine serving as an oil removal agent, OP-10 serving as an emulsifier, acetone, sodium carbonate and deionized water. In the cleaning method, the stainless steel substrate is cleaned by high-pressure spraying and ultrasonic oscillation. The surface cleaning agent and the cleaning method have the advantages that: polluted granules are adhered to the surface of a stainless steel belt in the process of machining the stainless steel belt or under the condition that the stainless steel belt is exposed in air, so dirt which is difficult to remove is formed; with the adopted anion surfactant, the surface tension of the stainless steel belt is reduced, so that pollutants are removed from the surface; and a complexing agent without metal ions has high complexing effect on stainless steel, so that a decontamination effect is improved. Simultaneously, the surface cleaning agent has the characteristics of simple preparation process, low cost, no toxicity, insusceptible combustion, safety, environment friendliness and the like, and can be recycled for multiple times.
Description
Technical field
The present invention relates to the preparation technology of solar cell, specifically be meant a kind of surface cleaning agent and purging method that is used at the bottom of the thin-film solar cells stainless steel lining.
Background technology
The energy and environment maintenance problem more and more are subjected to people's great attention and pay close attention in recent years, thereby have advanced the solar cell development, and solar cell will become following important substitute energy.The flexible substrate film solar cell is as the third generation product of solar cell, because that it has is in light weight, collapsible, be difficult for broken and have characteristics such as higher quality ratio, power, so many companies, R﹠D institution competitively begins one's study and develop.In the past, flexible thin-film solar cell was a substrate with the high molecular polymer polyimide mainly, but the low melting point of polymer substrate and problem such as easily aging have limited the use of battery.And then developed with the substrate of Stainless Steel Band as solar cell, also realized solar energy film material volume to volume automatic manufacturing technique simultaneously, be convenient to the big area continuous production, the potentiality that reduce production costs are very big, have very strong competitive power.
As everyone knows, no matter be Stainless Steel Band or sheet material, after processing such as casting, forging, hot rolling, cold rolling and thermal treatment, its surface all can stay obstinate oil stain and greasy dirt, as deals with improperly and will directly influence the quality of the subsequent technique and the product of product.Handle particularly importantly as the cleaning surfaces of the Stainless Steel Band of thin-film solar cells substrate, will be directly connected to the efficiency of conversion of solar cell, open voltage, short-circuit current.
Mainly contain following two kinds of methods in the market and clean stainless steel band surface: a kind of is to adopt the liquid detergent washing, flushing with clean water then, and this purging method does not obviously meet the semiconductor technology requirement; The another kind of persulphate that adopts strong oxidizing property, superoxide, potassium permanganate, heavy complex acid potassium, or highly acid sulfuric acid, hydrochloric acid, hydrofluoric acid, the mixed solution of sulfuric acid and hydrofluoric acid, or solution such as alkaline sodium hydroxide is as cleaning stainless steel band surface, this method not only causes to a certain degree pollution to environment, and make the original oxide film of stainless steel band surface discontinuous, imperfect, defectives such as melanoleukoderma, thereby cause stainless steel band surface when carrying out magnetron sputtering, the sticking power of the rete that obtains is low, directly influences the density and the result of use of plated film assembly.
Summary of the invention
Based on the defective that above-mentioned existing purging method exists, the objective of the invention is to propose a kind of surface cleaning agent and purging method that is used at the bottom of the thin-film solar cells stainless steel lining.
The preparation of surface cleaning agent:
Press raw material weight per-cent preparation: sodium lauryl sulphate 1.5～4.5wt%, ethanol 10～50wt%, Virahol 2.0～4.0wt%, trolamine 0.5～8.0wt%, OP-100.1～2wt%, acetone 1.0～5.0wt%, yellow soda ash 0.5～3.0wt%, all the other are deionized water.
Take by weighing by the above-mentioned raw materials weight percent, it is dropped in the beaker, beaker is placed on and has in the digital display water bath with thermostatic control whipping appts, bath temperature is that 40～80 ℃, stirring velocity are 400～1000 rev/mins, churning time is 10～30 minutes, obtains being used for the surface cleaning agent at the bottom of the thin-film solar cells stainless steel lining.
Purging method:
The above-mentioned surface cleaning agent for preparing is injected in the high-pressure spraying device, the high-pressure spraying stainless steel band surface, time is 2～5 minutes, and make the static placement 8～12 minutes in air of the Stainless Steel Band that sprayed, put it into subsequently in the deionized water of ultrasonic clear Xian's device, adopting frequency is that 20～40kHz ultrasonic oscillation takes out after 10～40 minutes and is cleaned Stainless Steel Band, promptly finish whole cleaning process, with the Stainless Steel Band behind clear Xian in 40～80 ℃ of vacuum drying ovens dry 20～30 minutes, promptly obtain the bright stainless steel band at last.
Anionic of the present invention has good emulsifying, infiltration, decontamination, foaming and dispersing property, and cleaning speed is fast and effect is obvious; Adopt the big ethanol of described volatility, Virahol as cosurfactant, the solvent that helps tensio-active agent reaches good wash-aid effect, cleans the back stainless steel band surface and can not stay the watermark mark; Described degreaser trolamine has good wetting, emulsification, infiltration, dispersive ability, makes greasy dirt weaken, break away from and enter washing lotion at the sticking power of metallic surface, thereby reaches the purpose of removal greasy dirt, clean surface; Described acetone can reduce striped as auxiliary agent; Described emulsifying agent is OP-10, has good wetting emulsifying effect; Described yellow soda ash is the common basic salt of clean-out system, and it is the extraordinary surperficial carrier of tensio-active agent.More than the weight percent of given component and each component be best, they have good performance complement synergistic function.
Great advantage of the present invention:
The methods such as strong oxidizer, strong acid or highly basic of having abandoned are removed impurity such as stainless steel band surface grease, and clean-out system of the present invention can realize removing under the weak basic condition the obstinate oil stain of stainless steel band surface, greasy dirt and dust etc., and cleaning performance is good.Under the ultra-sonic oscillation condition, can thoroughly remove greasy dirt, buffing wax, the stainless steel band surface degree of cleaning reach the requirement of vacuum magnetic-control sputtering plated film.
