BACK-CONTACT SOLAR CELL AND MANUFACTURING METHOD THEREOF

A back-contact solar cell and manufacturing method thereof includes steps of providing a substrate, forming a first conductive doping region and a second conductive doping region on the substrate, forming a passivation layer on the substrate to cover the first conductive doping region and the second conductive doping region, distantly disposing a plurality of first electrode paste clusters on the passivation layer, in which each first electrode paste cluster corresponds to the first conductive doping region and the second conductive doping region and includes a metal component and a glass component, enclosing the first electrode paste cluster by a plurality of second electrode pastes, and heating at least the first electrode paste clusters to an predetermined temperature so that the metal component, the metal component and the passivation layer contacted by the first electrode paste clusters forms a plurality of contacting regions.
