Hevel Group of Companies with NPP TAIS LLC developed a high-performance and record-breaking space solar cell battery in Russia. Moreover, the coefficient of solar energy conversion in AM1.5 standard spectrum exceeds 22%, while the specific mass of the solar panel does not exceed 1.5 kg/m2. The solar system has successfully passed the tests in a vacuum and critical temperatures (from –160 to + 120 °С) without any kind of characteristic deviations.

Unlike traditional solar cells based on triple-junction gallium arsenide solar cells, the new solar panel is 30% more efficient and its cost is significantly lower what enables wide application in commercial and scientific spacecraft.
