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 ). |
