Solar (photovoltaic) industry: Removal of residual sawing material from solar wafers


Solar cell, or photovoltaic (PV) cell, converts sunlight into electricity. Photovoltaics is a growing industry as it uses a CO2-free renewable energy source, the sun. 

The manufacturing includes the removal of sawing material after ingot slicing of solar wafers. After this process step, the wafers require cleaning, and this is done by the aid of acid baths. 

Photovoltaic manufacturers benefit from using Vaisala K-PATENTS® semicon refractometer as it can: 

  • Measure the bath concentration and ensure the correct concentration level
  • Help to determine the exact timing for bath replenishment. 

Vaisala’s application note explains how a semicon refractometer can improve process with recommended installation point for best performance.
