Customer ServiceProducers of solar cells from silicon wafers, which basically refers to the limited quantity of solar PV module manufacturers with their own wafer-to-cell production equipment to control the quality and price of the solar cells. For the purpose of this article, we will look at 3.) which is the production of quality solar cells from silicon wafers.
Customer ServiceWith GMAW (MIG/MAG, TIG and Plasma) three "toxic" gases are formed. They are nitric oxide NO, nitrogen dioxide NO2 and ozone O3. Of these gases, ozone has the lowest limit. You can smell ozone already at half the limit. At this level, a welder begins to experience various disorders. They increase in scope and intensity at higher concentrations.

Customer ServiceWelding has many consumables, many of which have debris or remains that are simply discarded as waste. This only scratches the surface; a comprehensive analysis of welding processes shows a wide range of potential environmental contaminants and impacts across the industry. Two things are undeniable.
The thickness of silicon wafer is 160 μm, the thickness of PV copper strip is 0.1 mm, the thickness of Sn alloy coating is 15 μm and 25 μm respectively. The physical properties of materials used in solar cell welding are shown in Table 6.
The ununiform temperature field, mismatched thermal expansion coefficient and local plastic deformation during welding are the root causes of residual welding stress. The influence of welding process on the yield of solar cells has been discussed above.
However, CIGS solar cells freed of toxic cadmium have already been successfully produced [ 39 ]. The toxicity of copper, indium, gallium, and selenium is considered benign. In addition, elemental selenium is capital in the human nutrition; daily absorptions of 500–860 μg of selenium are acceptable for long periods [ 40 ].
Since fumes are inevitably generated by welding, and they are one of the primary sources of direct environmental impact from welding, one of the most impactful things you can do is use a comprehensive fume extraction system for your welding operations.
The chemical composition of the particles and the amount of fumes produced during welding depend on the welding procedures, the chemical composition of the shielding gases, the filler and the base material, the presence of coatings and the time and severity of the exposure .
