SE SRTIIE

State Enterprise Scientific Research Technological Institute of Instrument Engineering

Department of microelectronic

SE SRTIIE specialize in the field of space instrument engineering, in particular development and manufacture of space solar battery, and radiation instrumentation technologies

Activities in APOLLON project

Development and manufacture of secondary optics elements (SOE) to increase the acceptance angle of Fresnel and Prismatic lenses
Prototypes of SOE will be developed, investigated and manufactured

Optimization of small area prismatic lens and parquet to increase optical efficiency
Optimized SOE will be developed, investigated which will allow to provide optical efficiency > 80 % and maximum homogeneity of light flux on solar cell surface at light incidence with angle >0.60.

Realization of optimized Point focus receivers
Optimized SOE will be produced and assembled with single receivers and strings of receivers for improving electrical parameters of receivers.

Optimization of "Chip on Flex" assembly technique with high heat dissipation
Optimized technique of assembly on the basis of "Chip on Flex“ technique the single receivers, strings of receivers will be designed. All connections of solar cells in the receiver will be executed by flexible aluminum - polyimide boards by ultrasonic welding. Aluminum - polyimide flexible boards will execute the functions of mechanical support, electrical connections, insulating elements and effective way of heat rejection. In combination with high thermo conductive pyrocarbon bases or with copper – polyimide foiled dielectrics, it is possible to provide high automation, and also high level of heat rejection.


Life time prediction and module pre-qualification

For life time prediction of receivers an accelerated thermocycle tests will be carry out for:

  • starting receivers;
  • optimized receivers;
  • COF receivers;

The test of receivers will be carried out according to requirements of following standards:

  • MIL-STD883E (method 1010.7 - Temperature cycling)
  • ECSS-Q-70-04A (Space product guarantee - Thermo cycling tests for checking processes and materials for space applications).
