Photos of a thin-film triple-junction space solar cell and a space solar sheet which is arrays of the thin-film cells laminated with transparent plastic films. They have been developed by a collaboration of JAXA and SHARP. The sheet has features of high efficiency (> 30 % under AM0), radiation hardness, lightweight as well as flexibility due to thin structure. It currently performs the highest specific power in the world. The cell and sheet will contribute to weight reduction and/or electric power enlargement of spacecraft. In addition, they are expected to be utilized for aircraft and autovehicles. (p.887)
