Electro-conductive paste, solar cell and method for producing solar cell

An electro-conductive paste set for use with solar cells comprising an electro-conductive paste for forming a bus bar electrode and an electro-conductive paste for forming a finger electrode, wherein:

• the electro-conductive paste for forming a bus bar electrode comprises an electro-conductive powder, a multiple oxide containing tellurium oxide, and an organic vehicle, wherein 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 wherein a content ratio of the tellurium oxide in 100% by weight of the multiple oxide as TeO2 is 3% by weight to 30% by weight,
• the electro-conductive paste for forming a finger electrode contains an electro-conductive powder, a multiple oxide in an amount of 0.1 parts by weight to 10 parts by weight based on 100 parts by weight of the electro-conductive powder, and an organic vehicle, and
• a content ratio of tellurium oxide in the multiple oxide in the electro-conductive paste for forming the finger electrode is higher than a content ratio of tellurium oxide in the multiple oxide in the electro-conductive paste for forming the bus bar electrode.
