Bifacial solar arrays of Russian space crafts

Bifacial solar arrays (BFSA) have high efficiency by converting the solar irradiation from the front side as well as from the rear side. The application of BFSA considerably expands capabilities of solar arrays and provides a number of important advantages before the one-sided version, The design parameters of developed in SPRE "KVANT" bifacial solar cells (BFSC) and solar arrays including BFSA of Russian spacecraft's new generation (Russian segments of the international space stations "Zarya" and "Zvezda", the Earth remote sensing satellite (ERSS)) are presented in the paper.
