Recently, the Korea Energy Research Institute (KIER) and Flexell Space announced the signing of a technology transfer agreement involving the process technology and proprietary know-how for ultra-light flexible CIGS (copper, indium, gallium, selenide) solar cells. The purpose is to jointly develop next-generation tandem solar cells for space applications (CIGS/perovskite double-junction solar cells).

Under the agreement, the space solar cell company Flexell Space will acquire KIER's ultra-light flexible CIGS solar cell technology. Both parties will collaborate to develop ultra-light thin-film double-junction solar cells optimized for the lifespan and performance of small satellites. In addition, the cooperation will focus on developing alternative markets to existing III-V space solar cells. It is reported that the total investment in the project amounts to 5.5 billion KRW (approximately US$4 million).
