Abstract

A system for harvesting solar energy on a spacecraft includes a stiff substrate layer and a working layer disposed on the substrate layer to provide at least one of a photovoltaic or a reflective function. In a first operational state, the substrate layer is arranged as a tape spring to store potential energy which causes the substrate layer to uncoil and provide, in a second operational state, a photovoltaic module and/or a solar concentrator.
