Solar cells on ultra-thin glass can boost energy systems for satellites, space materials

SMRTR summary

Scientists are developing lightweight cadmium telluride (CdTe) solar cells on ultra-thin glass for space-based energy systems. This cheaper, radiation-resistant alternative to current space solar cells targets 20% efficiency. The project, a collaboration between Loughborough and Swansea universities with industry partners, aims to reduce payload weight and enable longer space deployments, meeting the growing demand for efficient solar power in the booming space industry.
