Abstract:
1. A laminated, cylindrical solar battery, comprising: a plurality of cylindrical solar cell modules laminated concentrically in layers from an innermost module to an outermost module, said innermost module having a center wavelength of a sensitivity wavelength band that is longer than a center wavelength of a sensitivity wavelength band of said outermost module; a first transparent cylindrical layer covering said outermost module; a second transparent cylindrical layer concentrically inward of said innermost module that covers an inner surface of the innermost module; and a central passage along an axial center of the cylindrical solar battery; each one module of the plurality of cylindrical solar cell modules comprising a plurality of solar cells, arranged in a plurality of rows and columns, within a common cylindrical transparent synthetic resin material which is formed integrally in axial and circumferential directions, wherein each row extends axially and each column extends circumferentially; each one module of cylindrical solar cell modules further comprising multiple pairs of lead wires protruding from an end of said each one module out of the common transparent synthetic resin material, each one pair of said multiple pairs of lead wires corresponding to a row of solar cells of said one module and connecting said solar cells of said row of solar cells in parallel within said common cylindrical transparent synthetic resin material; and wherein each one lead wire of said each one pair of said multiple pairs of lead wires continuously extends an entire length of said corresponding row of solar cells with a first end of said each one lead wire of said each one pair protruding from one end of said each one module and a second end of said each one lead wire of said each one pair protruding from an opposite end, relative to said one end, of said each one module, wherein a first lead wire of said one pair is connected to one terminal of each solar cell in said corresponding row and another lead wire of said one pair is connected to a different terminal of each solar cell in said corresponding row, so as to form said parallel connecting of each solar cell in said corresponding row.
