Recommended application field: Power Engineering

Technical characteristic: Efficiency: 8-11 %, energy from a unit area ~100 W/м2.

Advantages over analogues: Project implementation would allow to create a new class of solar batteries for space vehicles with features superior to analogues: * higher specific power (not less than 1000 W/kg) with a possibility of further * increase subject to improvement of substrate production technology; * excellent compactness in transportable set-up; * lower cost due to absence of a rigid framework and use of an amorphous silicon structure; * availability of experience in development of similar assemblies tested in an orbital experiment ("Znamya" space experiment, 1993); * flexibility of changing dimensions of such a solar battery; * high reliability for a 20-year period of stand-alone operation mode; * little degradation by the end of service life; * design simplicity, low time to manufacture and put to ground and orbital trials; * possibility of using the rotating solar battery as a power gyro with partial transferring to it functions of space vehicle (SV) attitude control system in relation to mass center; * possibility of selecting dynamic parameters for which the rotating solar battery is similar to a rigid static design from the point of view of SV control.

The development stage readiness: Introduced in production

Description of the development:
()
Battery to be developed would employ a-Si alloy deposited on a polymer (kapton) film substrate from as photoelectric converter. A specific feature of this development is that the assembly would unfold from its packed (transportable) set-up and maintain its shape in operating position due to centrifugal forces. Implementation of this project will allow to create a new product for the market of solar batteries for space application distinguished by better characteristics, longer service life and lower cost.
