The present invention relates to a silicon solar cell module using conductive paste as an electrode. According to the present invention, a front electrode finger line is separated from bus bars, and the front electrode finger line is printed with existing silver paste for sintering at a high temperature, and the front and rear electrode bus bars are allowed to be formed of inexpensive and low-temperature conductive paste that contains a buffering agent and a curing agent, using reducing power so as to reduce products costs by replacing the expensive silver paste with the cheap and low-temperature conductive paste. The front electrode bus bar using the conductive paste according to the present invention does not come into contact with a silicon substrate, and thus decreases the contact surface area between silicon and a front electrode, reduces a decrease in current caused by the recombination of electrons and holes caused by the contact surface, and increases photoelectric conversion efficiency ...
