Abstract

We have successfully developed silver powders with a high dispersity and high tap density (>5.5g/cm3) used in silver paste for the front electrode of solar cell by using graphene due to its hydrophobicity, and we also achieved the prepared in industrial scales. The performance of the powder is similar to the same one imported from abroad, individual performance is higher than similar products. And the technical indicator of silver products by us is following, particle size (D50 1.5~2.5μm), tap density (>5.5g/cm3). What’s more, we have successfully prepared the graphene modified silver pastes with high photoelectric conversion efficiency and good printing performance because of graphene high conductivity and lubricity, and we also achieved it’s industrialization. Meanwhile, the average photoelectric conversion efficiency of graphene modified silver pastes is 0.2% higher than the normal silver paste, the printing performance and aspect ratio of the graphene modified silver pastes is also better than the normal one.
