With a solar ball 10 serving as a light-receiving semiconductor apparatus, the outer surface of a spherical solar cell 1 is covered with a light-transmitting outer shell member 11, and electrode members 14, 15 are connected to electrodes 6, 7 of the solar cell 1. The outer shell member 11 comprises a capsule 12 produced by bonding together two halves, and a filler 13 that is packed inside this capsule and cured. A solar panel can be configured such that a plurality of the solar balls 10 are arrayed in a matrix and connected in parallel and in series, or a solar panel can be configured such that a multiplicity of spherical solar cells 1 are arrayed in a matrix and covered with a transparent outer shell member. A solar string in the form of a rod or cord can be configured such that a plurality of the solar cells 1 are arrayed in columns and connected in parallel, and then covered with a transparent outer shell member. Since the outer shell member 11 condenses light, the light-receiving area of the solar cell 1 can be expanded. Also discussed is a light-emitting semiconductor apparatus in which a spherical semiconductor device with a light-emitting function, rather than the solar cell 1, is covered with an outer shell member.
