6 FAQs about [Measurement of line width of photovoltaic cell mesh]
What is a fine mesh solar cell screen?
Fine mesh screens enable intricate patterns of solar cell grid designs. Stainless steel mesh is used by most solar cell manufacturers for the front side metallization process. However, finer diameter wires also lead to lower theoretical line heights which are detrimental to high aspect ratio.
How to determine the width of screen printed lines?
The width of screen printed lines can be decided by the emulsion opening of a screen mask of screen printing, but actually the printed width is very much affected by the roughness of a substrate and the rheology of the paste used. Finger lines of solar cells should be as narrow as possible to increase sunlight usage efficiency.
How wide should finger lines be for a solar cell?
Finger lines printed on solar cells should be as narrow as possible to increase sunlight usage efficiency. But it has been said “For screen printing it is difficult to achieve fine lines with high aspect-ratio.” The actual finger lines are around 70-100μm in width in massproduction. It would be challenging to make finger lines less than 50μm.
What is the mesh count of a screen?
The first screen has a mesh count of MC = 360 1/inch, a wire diameter of d = 16 µm and a screen opening width of w n = 40 µm. The second screen has a mesh count of MC = 380 1/inch, a wire diameter of d = 14 µm and a screen opening width of w n = 30 µm.
What is a mesh size?
The first mesh was made out of a mesh count MC = 380 inch −1 with a wire diameter of d = 14 µm and the second mesh had a mesh count of MC = 480 inch −1 with a wire diameter of d = 11 µm. The screen angle was the same for both screens at φ = 30°.
How does screen printing work for metallization of solar cells?
