Abstract
The invention discloses an electrode paste in contact with a p+ emitter of an N-type solar cell, and relates to the technical field of photovoltaic cells. The electrode paste of the present invention comprises the following components by weight: 80-90 parts of a conductive silver powder, 0.5-3 parts of an aluminum powder, 3-8 parts of a glass powder, 0.1-2 parts of a lanthanum-aluminum alloy powder or lanthanum-ytterbium-aluminum alloy powder, 6-10 parts of an organic vehicle and 0-2 parts of an auxiliary agent. By selecting the components and formulations of the electrode paste, the electrode pastes of present invention obtained improve the conversion efficiency of a N-type solar cell that can exceed 23.5% after the electrode paste being applied to the N-type solar cell.
