Photovoltaics (PV)

Solar photovoltaics have become one of the most environmentally-friendly means to generate electric power. ETHOCEL™ ethyl cellulose polymers deliver high-value and superior performance. They are ideal binders and rheology modifiers for the following PV pastes and screen-printing technologies:

  • Monocrystalline PV
  • Polycrystalline PV
  • PERC PV
  • Bifacial PV
  • Front-side silver paste
  • Back-side silver paste
  • Back-side aluminum paste

Functional Benefits

  • Excellent solubility in a wide range of organic solvents
  • High-quality, consistent viscosity
  • Outstanding thixotropic property, essential for screen-printing
  • Strong adhesion of the printed metal to the substrate
  • High purity and low firing residues: excellent ohmic contact formation
  • Low bowing and good backside field (BSF) formation
