Properties of Ethyl Cellulose used in conductive paste for solar cells.
Ethylcellulose is the ideal binder for conductive paste inks, due to its high purity, clean burn-out, adjustable rheological performance and outstanding batch-to-batch consistency
• Best performing ethyl cellulose with unique organo-solubility and outstanding stability due to advanced production process
• Good solubility and low impurities allows reduction of filtering costs
• Narrower and higher electrodes with sharper edges that contribute to high conversion rates for photovoltaic cells
• Formulation flexibility and reduced rheology adjustment costs
