Solar concentrator |
摘要 |
A space solar concentrator based on light-weight reflectors (3) attached to a honeycomb panel (1) is described. The integration of the reflectors (3) allows for a high modularity. Solar panel deployment is not perturbed by the reflectors (3) even with two-dimensional deployment concept. Each reflector (3) consists in small saw tooth aligned as rows (2) with solar cell rows in between. Low concentration is achieved with a high level of thermal control and a high optical efficiency. When small off-pointing occurs, the solar flux distribution is still the same on each cells. It guarantees a good electrical control and management on the whole panel. The reflectors (3) are preferably made of a thin film tight on a light-weight rigid frame deployed after launch. In another embodiment, the reflector is not deployable and is part of the panel substrate. A stowed configuration allows for superimposition of the solar panel. High reflectivity of the reflectors results from the use of vacuum deposited aluminum or preferentially over-protected silver.
