| titleOfInvention | Solar cell back electrode |
| abstract | The invention discloses a back electrode of a solar cell and a manufacturing method thereof. The manufacturing method includes: (a) preparing a substrate, the substrate including a semiconductor layer and a passivation layer formed on the back of the semiconductor layer, wherein the a passivation layer having one or more openings; (b) applying an aluminum paste to the backside of the substrate, the aluminum paste comprising: (i) aluminum powder; (ii) glass frit based on cations in the glass frit The glass frit comprises 30-70 cation mole % lead, 1-40 cationic mole % silicon and 10-65 cationic mole % boron, and 1-25 cationic mole % aluminum, based on the total moles of components; and (iii) an organic medium, wherein the aluminum paste covers the opening; and (c) firing the aluminum paste in a furnace, wherein the aluminum paste does not fire through the passivation layer during firing. |
