CONDUCTIVE ALUMINUM PASTE FOR HIGH-EFFICIENCY SOLAR CELL AND SOLAR CELL REQUIRING THE CONDUCTIVE ALUMINUM PASTE

摘要

A conductive aluminum paste for a high-efficiency solar cell includes an aluminum powder, an organic carrier, and at least a rare earth element oxide. The rare earth element oxide accounts for a maximum 5% of the total weight of the conductive aluminum paste. A solar cell including the conductive aluminum paste is further provided. The conductive aluminum paste and the solar cell are effective in enhancing solar photovoltaic conversion efficiency and eliminating warpage without increasing the content of the fine aluminum powder.
