Abstract:
1. A light-emitting or light-receiving semiconductor module, comprising: a pair of sheets including a first sheet made of a transparent insulating material, a second sheet made of an insulating material and disposed parallel to the first sheet, and a plurality of granular semiconductor cells disposed in a configuration forming a plurality of rows and a plurality of columns in between the first and second sheets wherein said semiconductor cells are each disposed in one of said rows and one of said columns, wherein each of said semiconductor cells comprises a p or n type semiconductor granule, a pn junction formed by an outer layer of the semiconductor granule, and first and second electrodes formed at first and second opposing portions of the semiconductor granule and respectively connected to first and second ends of the pn junction wherein the first ends of the pn junctions are at one of a p type material and an n type material of the pn junctions and the second ends of the pn junction are at another one of the p type material and the n type material of the pn junctions, and the pn junction has a light-emitting or light receiving function, each of said semiconductor cells is disposed in a state such that a conduction direction defined by orientation of said first and second electrodes is perpendicular to the pair of sheets, said semiconductor cells are grouped into a plurality of groups each of which includes a plurality of said semiconductor cells having a common conduction direction, and said groups being arranged adjacent one another, conductors disposed on inner surfaces of said first and second sheets which oppose one another, said conductors connecting said semiconductor cells such that, for each respective one of said groups, said semiconductor cells thereof are electrically connected in parallel to each adjacent others of said semiconductor cells of said respective one of said groups thereby electrically connecting together the first electrodes of said semiconductor cells of said respective one of said groups, and thereby electrically connecting together said second electrodes of said semiconductor cells of said respective one of said groups; and said conductors electrically connecting said groups in a series connection with each other such that said first electrodes of said semiconductor cells of ones of said groups are electrically connected to said second electrodes of adjacent ones of said groups to be thereby aligned to electrically conduct in a common electrical direction in said series connection, wherein:
