How to solve the solar cell production process pollution?
PV cell manufacturing plant today are facing increasing production efficiency, improve the efficiency of the pressure of its products, the other dramatic changes in the prices of raw materials also contributed to also make the imperative. Of improving production efficiency and product efficacy is one of the main problems in the production environment pollution often repeated, if the coating, printing or laminating process before the material surface contamination, production efficiency will be seriously affected.
Pollution can affect the production of solar modules, depending on which module solar module production. Module production in three ways:
The first generation of solar cells – silicon – dust and dirt can affect the screen printing process, raises many questions such as ‘tombstoning phenomenon’, open and short circuits. When the tin solder and volatile pollutants in the rapid expansion will lead to lack of weld, and dry welding. Solar cell is then encapsulated in EVA film. Between the film and batteries if there is dust or pollution particles, because the block sunlight, the efficiency of the final product will be reduced. Even the tiny invisible pollution particles, because there are ‘tent effect’ to the surface pressure in the complex ‘fish eyes’, can produce visual defects. These are the plants to try to avoid.
Second-generation solar cells – Vacuum alloy – more efficient, but before entering the deposition process the surface of the substrate junction must be very clear. If there is pollution particles in the connection circuit, there will be and the same problems as the first generation of technology, such as ‘fish-eye’ and ‘tombstoning’ and so on. Similarly, if you want to achieve the best efficiency of the battery in the packaging phase the surface of glass or film must be clean.
Third-generation solar cells and for the electronics industry use similar screen-printing technology. Usually this type of battery is not the first and second-generation high, so do not even reduce the efficiency of pollutants is very important. Therefore, the substrate and the template must be printed at each step thoroughly before cleaning. General substrate for screen printing of plastic material or metal foil, the coating into the substrate or deposition before the direct arrival from the manufacturer, usually contaminated with residues. For example, the plastic film will generally be cut according to customer requirements into different sizes, probably debris left in the material surface, electrostatic attraction of dust is also a serious problem.
Use contact cleaning equipment to remove silicon, glass or other substrate surface EVA film to a small loose-micron pollution particles, without damaging the substrate surface.
Pollution not only cause problems in the production process. If contaminants are conductive materials can cause corrosion products, may only late in the product, when stored in the warehouse of the time will be found. So what can be done to minimize pollution of solar cells for the production of impact? After many production plants to draw on proven technology was the semiconductor industry – contact cleaning technology.
Use contact cleaning equipment to remove silicon, glass or other substrate surface EVA film to a small loose-micron pollution particles, without damaging the substrate surface. A global leader in contact cleaning equipment suppliers Teknek, using its special rubber roller surface of the substrate removed from the pollution particles, and then transferred to the sticky paper for final processing and analysis. Teknek latest Nanocleen technology can efficiently remove small particles of pollution to the nanometer level. In every possible surface contamination processes using contact cleaner, can significantly improve production efficiency and the effectiveness of solar cells. With other cleaning methods such as non-contact technique compared with vacuum or blow because it is difficult to effectively break the chip surface boundary layer of air, it can not effectively remove small particles of pollution, contact cleaning has proven to be the most efficient surface Dust and clean way.
With the rising prices of raw materials, solar cell production plant have to find a suitable increase production efficiency and reduce waste approach. Pollutants on productivity and efficiency of solar cells themselves have a major impact. Contact the production and clean technology to improve the efficiency of the battery provides an optional best solution.
