Abstract
A method for manufacturing a solar cell includes forming a passivation layer on a rear surface of a substrate of a first conductivity type; forming connecting electrodes having a plurality of electrical contacts that are in contact with the rear surface of the substrate by using a first paste for a first temperature firing on portions of the passivation layer; and forming a rear electrode layer by using a second paste for a second temperature firing on the passivation layer and the plurality of electrical contacts, wherein a temperature of the second temperature firing is lower than a temperature of the first temperature firing.
