Claim:
1. A solar cell module comprising a plurality of solar cells, each of the solar cells comprising a spherical semiconductor element, the solar cells being arranged so as to form a matrix of the spherical semiconductor elements, the matrix having a plurality of rows and a plurality of columns; each spherical semiconductor element comprising a p type or n type spherical semiconductor and a pn junction having a shape of a partial sphere on an outer surface of said spherical semiconductor; a plurality of conductive directions of said spherical semiconductor elements being directed in a direction parallel to a column direction of said matrix; a plurality of spherical semiconductor elements in each said row being electrically connected in parallel and a plurality of spherical semiconductor elements in each said column being electrically connected in series; wherein the solar cells comprise a plurality of solar cell arrays and each of the solar cell arrays is comprised of a respective one of said rows of spherical semiconductor elements, a pair of lead members and a plurality of bypass diodes, said pair of lead members connecting the spherical semiconductor elements of said respective row to said plurality of bypass diodes in reverse parallel; wherein respective said lead members are positioned between adjacent rows of said plurality of rows so as to be shared by the solar cell arrays comprising said adjacent rows; wherein each of said lead members comprises a plurality of lead pieces formed on at least two end portions of said lead member and extending from the lead member in a lengthwise direction of the lead member, each lead piece having a length in said lengthwise direction which is larger than a diameter of said spherical semiconductor elements and larger than a dimension in said lengthwise direction of said bypass diodes; and the lead pieces extending from the lead members in a lengthwise direction of the lead members; wherein a pair of panel members are disposed in parallel each on a respective side of said plurality of solar arrays; wherein said lead pieces are disposed between the panel members of said pair of panel members orthogonally to said panel members; and wherein distance between the panel members of said pair of panel members is the same as a dimension of said lead pieces orthogonal to said lengthwise direction.
