ABSTRACT: This work discusses challenges and advantages of cut solar cells, as used for shingling and half-cell photovoltaic modules. Cut cells have generally lower current output and allow reduced ohmic losses at the module level.
The structural construction of the machine is rigid and vibration-free and effective for cutting applications. The machine also includes vacuum plates, which do not have any potential for errors in solar cell breakdown.
And if smaller formats begin to disappear from the market, as many in the industry forecast, cell-cutting processes are likely to become even more ubiquitous in PV manufacturing. Avoiding damage to the edge of the cell during the cutting process has been a challenge for the industry.
Automation in the Solar cell cutting machine has changed the scenario of the production industry. The machine is very stable, utilizes very low electricity, and automatically processes the solar cell metal chips which have made it possible to have an uninterrupted production flow.
Photovoltaic (PV) modules with half-cut cells have become state of the art in the industry today . Compared to full-cell modules, ohmic losses are reduced through lower generated current. Alternative module configurations, such as shingling, have also gained attention due to their potential for further enhancing power density [2–5].
