Edge deletion processing for thin-film solar cell battery

・Surface roughness finishing, 67% drastic improvement @ edge deletion process

Comparing the edge deletion process by conventional sandblast process, surface roughness finish has been drastically improved almost to less than 1/3 level with same process efficiency and improvement for the issue “polishing material sticking in the substrate” 

・Process Cost saving compared with the sandblast processing

If same surface roughness finish level for the edge deletion as the sandblast processing is required, its processing tact time with lager size of polishing particle will be shorter than the sandblast processing case.

・Maintenance is easy.

Easy maintenance due to no cabinet use.

・Enabling for edge deletion processing without masking

It is possible to process the edge deletion process without masking, this means no masking on the substrate and no mounting of masking plate.

・The consumption of the abrasive is a little.

Compared with the sandblasting  jetted right above, damage and the consumption of the abrasive decrease  so that the abrasive may run on the surface of the substrate.

・The surface grinding of the substrate is possible at a low price, because the grinding material is made to run on the surface of the substrate.
