Angstrom Designs

Angstrom Designs is a United States company focused on research, instrumentation, and test and measurement for space grade photovoltaic power. Its website says it was founded in 2011 and is based in Santa Barbara, California. The company develops testing and calibration processes for prime contractors, solar panel integrators and photovoltaic researchers, who use them to measure solar cells and panels for use in space.

Products and services

• Orbital testing: customers can fly solar cells or modules on the International Space Station for six months and get them back, with monthly data deliveries that include IV, temperature and sun angle data
• Zero atmosphere (AM0) solar simulation with its patented programmable LED solar simulator, called pLEDss
• Automation, instrumentation and measurement for cells and panels in orbit, in near space and in the lab
• High altitude balloon flight services for testing in near space

Technology

The site says the pLEDss gives light beams with higher accuracy and better spatial and spectral quality than older solar simulation systems. It supports spectral tuning and junction current matching, which matters for multi-junction cells, and the process can be fully automated to give key measures of cell health. For the orbital program, correction and filtering tools produce degradation curves and temperature coefficients from more than 1,500,000 IV curves per cell, and customers do not need space flight experience because they only mount cells on the supplied holders and mail them in. Sign up for a June 2027 launch closes in November.

Work with NASA

Press releases say its high altitude balloon flight services were selected for a NASA IDIQ program in July 2024, and that it would perform solar array testing to support the NASA Gateway lunar space station, part of the Artemis program.
