Targets

Smart and easy way to boost the efficiency of multicrystalline solar cells:

  • Optimize wafer surface topology
  • Achieve higher current Isc
  • Increase multicrystalline solar cell effi ciency

Application

Additive for multicrystalline solar cell production:

  • 100 % water soluble: Easy to rinse with water
  • Environmentally friendly
  • Easy dosing: manual and automatic
  • Can be used in any standard texturing equipment
  • Supports higher texturing temperatures:
    less energy consumption for cooling

Solution

MULTI-TEX the new additive for next generation texturing processes:

  • The molecular structure is designed to optimize the standard HF-HNO3 acidic texturing process
  • Modification of wafer surface reduces the reflectivity by up to 20 % (rel).
  • Significant increase of current Isc: More cells >8.8 A
  • MULTI-TEX enables average effi ciencies of >18 %

Benefits for Production

Join the future of acidic texturing:

  • Signifi cant increase of current Isc
  • Higher average cell effi ciencies: +0.1 % abs.
  • Higher selling prices for multi cells
  • Low additive consumption
  • Supports higher texturing temperatures:
    less energy consumption for cooling
