Abstract
For the improvement of space photovoltaic cell efficiency, an astromesh deployable concentrator for space concentrating photovoltaic (CPV) system is proposed. A deployable solar parabolic concentrator with an aperture radius of 3 m and a concentration power of 35 kW has been designed. The astromesh deployable concentrator has a high degree of solar concentration, lightweight, and easy deployment, which has an advantage over inflatable deployable concentrator and rigid concentrator. We analyse the performance of the CPV system simulated by software Lighttools, and the results indicate the CPV system can generate 270W electrical energy per kilogram, so the utilization of solar energy have been enhanced effectively. This system can be used for the support of various spacecrafts power and space solar power station.
