Abstract
A space solar cell includes a back surface electrode formed on a back surface opposite to a light receiving surface of a semiconductor substrate, and a dielectric layer formed between the back surface electrode and the semiconductor substrate. In the space solar cell, a plurality of openings are formed in the dielectric layer for establishing an electrical connection between the back surface electrode and the semiconductor substrate, and a ratio of an area occupied by the openings relative to an area of the back surface is within a range from 0.25% to 30%.
