Conductive paste for solar cell

The invention discloses conductive paste for a solar cell. The conductive paste comprises conductive metal powder, glass powder and an organic carrier, wherein the organic carrier comprises a thermoplastic polymer, vinyl silicone oil, a polymerization inhibitor, other organic auxiliaries and an organic solvent. The vinyl silicone oil is used for replacing traditional silicone oil, meanwhile, a proper amount of polymerization inhibitor is added, the photovoltaic conversion efficiency of a solar cell can be improved by increasing the depth-width ratio of a formed grid line and reducing fluctuation of the grid line, and the stability of the conductive silver paste can be kept. 本发明公开了一种用于太阳能电池的导电浆料，包含导电金属粉、玻璃粉、有机载体；其中，有机载体包括热塑性聚合物、乙烯基硅油、阻聚剂、其他有机助剂、有机溶剂。通过使用乙烯基硅油代替传统的硅油，同时添加适量的阻聚剂，不仅可以通过增加其形成的栅线高宽比和减低其栅线的起伏来提高其太阳能电池的光伏转化效率，还可以保持其导电银浆的稳定性。
