Zusammenfassung: | The invention provides solar cell conductive silver paste free of silicone oil and application thereof. Raw materials of the conductive silver paste comprise silver powder, glass powder, an organic carrier and a polymer additive, and the polymer additive comprises a dendritic polymer and a polar solvent. The invention further provides a solar cell which comprises the solar cell conductive silver paste free of silicone oil. According to the conductive silver paste provided by the invention, silicone oil does not need to be added, and the problems that the silicone oil cannot be completely volatilized in the sintering process, silicon residues exist, the series resistance of a battery piece is increased, and sintering is poor in the front conductive silver paste containing the silicone oil are solved.
本发明提供了一种不含硅油的太阳能电池导电银浆及其应用。该导电银浆的原料包括银粉、玻璃粉、有机载体和聚合物添加剂,其中,所述聚合物添加剂包括树枝状聚合物和极性溶剂。本发明进一步提供了一种太阳能电池,其包括上述不含硅油的太阳能电池导电银浆。本发明提供的导电银浆无需添加硅油,避免了含硅油的正面导电银浆存在硅油在烧结过程中不能完全挥发、存在硅残留并会造成电池片串阻升高、烧结不良等问题发生。 |
