The improvement comes from providing energy generation and storage in one package that can either radiate heat away or direct it to other necessary components. It is designed as a tile that outputs and stores a specific amount of power. The tile can either be single sided, and coat the outside of the spacecraft such that the waste heat generated can be radiated away, or it can be dual-sided, with the whole assembly isolated out on a strut from the spacecraft it is powering, like a solar panel. What's more impressive is that the tiles can be strung together—need a higher power output? Simply select the number of tiles right for your application.
