  • Publication number: 20190312160
    Abstract: A method of manufacturing an electrode for a solar cell includes printing a conductive paste on a front surface of a substrate using a printing mask having an opening rate of 65% or more, and baking the printed conductive paste. The conductive paste may include a conductive powder, a glass fit, and an organic vehicle, the glass fit may include lithium oxide and tungsten oxide, and, in the glass fit, a weight ratio of lithium oxide to tungsten oxide may be about 0.5 to about 5.5.

  • Publication number: 20180138335
    Abstract: A front electrode for a solar cell includes a substrate, a first conductive layer on the substrate, and a second conductive layer on the first conductive layer. The second conductive layer is formed of a composition including silver powder as a first metal powder; and at least one of tin powder, lead powder, and bismuth powder as a second metal powder. The second metal powder is present in an amount of about 0.1 wt % to about 15 wt % based on the total weight of the first conductive layer and the second conductive layer in an unbaked state of the first conductive layer and the second conductive layer.
