Abstract
An electrode paste for a solar cell comprising electrically conductive particles, lead-free glass frit, a resin binder and zinc oxide particles, wherein zinc oxide particles having a specific surface area of 6 m2/g or less are contained at 10% by weight or more based on the total amount of zinc oxide.
Claims6
An electrode paste for a solar cell comprising:
- electrically conductive particles, wherein the electrically conductive particles comprise silver, and where the electrically conductive particles are between 70 and 90% by weight based on the weight of the paste, glass frit, a resin binder and zinc oxide particles, wherein zinc oxide particles having a specific surface area of 3 m2/g or less are contained at 10% by weight or more based on the total amount of zinc oxide, and wherein said zinc oxide particles are present in an amount of 0.1 to 10.0% by weight based on the total weight of the paste.
