DEVELOPMENT AND ON - ORBIT RESULTS OF SOLAR CONCENTRATED PADDLES WITH THIN FILM REFLECTOR

摘要

This paper describes the development and on-orbit result of solar concentrated paddles with thin film reflectors. Concentrated solar radiation with 1.2-1.3 solar intensity is irradiated on the triple -junction solar cell with 27 % efficiency. The solar paddles were applied to the small scientific satellite INDEX (REIME1) for aurora observation and demonstration of advanced satellite technologies. REIMEI is a small satellite with 72kg mass, and is provided with three-axis attitude controlled capabilities for aurora observation. REIME1 was launched into a nearly sun synchronous polar orbit on Aug. 23rd, 2005 (UT) from Baikonur, Kazakstan by Dnepr rocket. A power of 160W is generated in the orbit by the solar paddle system with total 3 kg mass. The concentration ratio is found to be about 1.2 and the system works well in orbit as predicted from the design and the ground test.
