The present invention relates to a
silicon solar cell module comprising electrodes formed from
conductive paste. In the invention, front
electrode finger lines and front
electrode bus bars are separately formed. The front
electrode finger lines are formed by printing a
silver paste and calcining the printed
silver paste at high temperature, and rear electrode
bus bars and front electrode
bus bars are formed from an inexpensive lower-temperature
conductive paste including a buffer and a curing agent having reducing power, whereby the expensive
silver paste is replaced with the inexpensive low-temperature
conductive paste, thereby reducing the production cost. Because the front electrode bus bars formed from the conductive paste do not come into contact with the
silicon substrate, the area of contact between the
silicon substrate and the front electrode is reduced, and thus the decrease in
electric current caused by the recombination of electrons and holes resulting from this contact is inhibited, thereby increasing the
photovoltaic conversion efficiency of the
cell. Also, when the conductive paste is used, the rear electrode and front electrode bus bars are calcined at low temperature, and thus the occurrence of cracks in the silicon substrate is reduced, thereby preventing a decrease in the
photovoltaic conversion efficiency of the
silicon solar cell and increasing the yield of the
cell.
