NOVELTY - The module has several solar cell elements that are provided with upper and lower electrodes arranged in upper and lower surfaces of a semiconductor substrate respectively, where the electrodes have different polarity. The upper electrode of one solar cell element is connected to lower electrode of adjacent solar cell element. The lower electrode is formed with a translucent current collection portion.    USE - Solar cell module.    ADVANTAGE - Since the translucent current collection portion of lower electrode is provided in the lower surface of the substrate, light reception amount of the solar cell element can be increased and output characteristics of the module can be improved. Hence, highly efficient solar cell module having simple structure can be obtained. The decline in electric power generation efficiency of the module can be suppressed by carrier recombination in the lower surface of the substrate. The movement distance of carrier and the output extraction portion of the electrodes can be shortened and resistance loss can be suppressed. The reflection of light on the surface of current collection portion can be reduced, since antireflective film is provided on the current collection portion. The carrier collected by the current collection portion can be efficiently transmitted to the output extraction portion, since current collection portion is electrically connected to output extraction portion through connection portion. The contact of wiring with connection portion can be avoided so that short-circuits can be prevented. Since the area of depletion region can be increased, the collection efficiency of carrier can be raised. The damage layer can be removed after the formation of through-hole.
