Orbital Test and Solar Simulation for Cells and Panels

Solar Testing

Advancing Zero-Atmosphere Solar Cell and Panel Testing

Angstrom Designs helps you test solar cells and panels in orbit, in near-space, and in your lab. At Angstrom Designs, we develop advanced testing systems that provide prime contractors, solar panel integrators and photovoltaic (PV) researchers with the accurate testing of panels, coupons and cells. Our patented programmable LED solar simulator technology addresses the challenging testing requirements of multi-junction solar cells, and our flight services can take your cells to near-space and into orbit.

Fly Your Cells on the ISS

Fly your cells or modules on the International Space Station (ISS) for 6 months, and then get them back. Monthly data deliveries include raw and processed IV, temperature, and sun angle data.

Advanced correction and filtering tools generate degradation curves, temperature coefficients, and more from over 1,500,000 IV curves per cell. Download the OEL brocure for more.

You don't need space flight experience. Just mount your cells on our holders and mail them in.

LED Solar Simulation

In zero-atmosphere (AM0) simulations, our programmable LED solar simulator (pLEDss) outperforms legacy solar simulation systems by providing light beams with higher accuracy and greater spatial and spectral flexibility. Traditional lamp-based solar simulators fall short of being able to accurately test solar cells with more than three junctions. Our pLEDss technology enables us to measure everything from silicon to thin-film to state of the art 6-junction solar cells.

The testing process can be completely automated, delivering crucial metrics for solar cell health. This highly flexible testing platform also provides spectral tunability and junction current matching capabilities.
