A light receiving or light emitting modular sheet having a plurality of
spherical elements arranged in matrix. It is constituted only of
acceptable spherical elements and photoelectric conversion efficiency
thereof is enhanced.The light receiving modular sheet (1) comprises a
plurality of spherical solar cell elements (2) arranged in matrix, a
meshed member (3), and a sheet member (4). Each solar cell element (2)
comprises a spherical pn junction (13), and positive and negative
electrodes (14, 15) formed oppositely while sandwiching the center of the
solar cell element (2) and being connected with respective electrodes of
the pn junction (13). The meshed member (3) has a plurality of conductive
wires (20, 21) arranged in parallel in order to connect the plurality of
spherical solar cell elements (2) in each column electrically in
parallel, and insulating tensile wires (22) arranged between the rows of
solar cell elements (2) to cross the conductive wires (20, 21)
perpendicularly while being woven in a meshed form to secure the
plurality of conductive wires (20, 21).
