Integrated type solar battery

摘要

An integrated type solar battery comprises a plurality of solar batteries serially connected. An upper electrode of one of adjacent solar batteries and a lower electrode of the other solar battery are connected via a lead wire. A groove portion of a boundary of the adjacent solar batteries is filled with an insulative material to a thickness enough to cover edge portions of the adjacent solar batteries. A conductive material is arranged so as to connect an upper portion of the insulative material and the upper electrode of one of the adjacent solar batteries. The lead wire is arranged over the insulative material along the groove portion of the boundary of the adjacent solar batteries so as to be connected to the conductive material. The lead wire is connected to the lower electrode of the other solar battery.
