Si-Core Modules

Pre-connected, cover glass integrated strings of silicon cells, delivered tested and ready to bond onto any rigid substrate — configurable from short strings to 12-cell modules.

Choose the module length by the number of cells in series: every added cell adds 94 mm of length and 4.16 W of AM0 power (ST102-10 reference module: 184 mm × 946 mm, 41.6 W). Redundant interconnects, end termination configurable, cover glass thickness to your requirement.

Key featuresSi-Core · Modules
01

Scalable length

Customizable number of cells in series, up to 12 per module — the length and power follow the cell count.

02

Silicon, 20 % AM0 class

Radiation resistant silicon substrate, high 20 % AM0 efficiency class; designed and tested for 7 years in LEO.

03

Cover glass integrated

Delivered with cover glass, thickness customizable; highly ATOX resistant.

04

Redundant interconnects

Cell-to-cell interconnects are redundant and debris-impact resistant; end termination configurable to your demands.

05

Ready to bond

Silicone-based adhesive recommended; tested on polyimide, FR-4 and CFRP substrates, rigid and flexible.

06

Tested per module

Visual inspection, IV at AM0, EL inspection and dimensional check on every module; DAkkS-accredited ASTM E490-00a AM0 measurement.

ConfiguratorModule length by cell count · values scaled from the datasheet

Choose the length — the power follows.

Every cell in series adds 94 mm and 4.16 W at AM0 (BOL, 25 °C). Current stays constant along the string; voltage and power scale with the number of cells. Reference: ST102-10 module, 946 mm, 41.6 W.
