摘要： An electro-conductive paste which includes an electro-conductive powder, a multiple oxide containing tellurium oxide, and an organic vehicle. The electro-conductive paste contains 0.1 parts by weight to 10 parts by weight of the multiple oxide based on 100 parts by weight of the electro-conductive powder, and the content ratio of the tellurium oxide in 100% by weight of the multiple oxide as TeO2 is 3% by weight to 30% by weight.

摘要： Provided is a conductive paste for forming a bus bar electrode having high adhesive strength on a passivation film in a crystalline silicon solar cell without having a detrimental effect on the passivation film so as to affect solar cell properties. The conductive paste is a conductive paste for forming an electrode formed on a passivation film of a solar cell, containing: (A) conductive particles, (B) an organic vehicle, and (C) glass frit containing Bi2O3 at 10 mol % to 30 mol % and SiO2 at 5 mol % to 30 mol %, wherein the conductive paste contains the glass frit at 0.3 parts by weight to 2 parts by weight based on 100 parts by weight of the conductive particles.
