The photovoltaic cell is the base element in the manufacture of a photovoltaic module: for this reason Helios Technology has the best technology to produce 156 x 156mm mono and poly crystalline silicon cells with a respectively efficiency up to 16,5% and 17,5%.

The row material, utilized in the productive process, is the high purity mono and poly silicon wafer, that is then transformed into a solar cell thanks to a chemical-phisical process.
Such process is fully automated and controlled in every single phase, thanks to in-line and off-line measuring instruments performing on samples basis.
Thanks to an appropriate software MES (manufacturing excution system) is possible to guarantee 100% of quality control, traceability and production improvements, to every single step, until the cell is ultimated. In order to guarantee such high quality, the following tests are performed:
• electrical tests at 500-1000 W/m2 (STC)
• very restricted current range classification in orderto minimize the mismatch,
• Isolation resistance measurements in dark conditions in order to prevent Hot Spots events
• several visual camera checks in order to obtain aesthetic uniformity

ADVANTAGES:
• High electric temporal stability of the modules, obtained with the utilization of crystalline silicon technology
• Excellent behavior at low sun radiation, thanks to an high shunt resistance, measured on every single cell
• Excellent module spectral response, thanks to advanced cell production technology
