Full wing qualification testing and incremental program update for the solar probe plus array As the Solar Probe Plus (SPP) program moves into the flight hardware build phase, the final testing of the qualification panel has been completed. The rigorous testing is many orders of magnitude more intensive than that used for standard earth-orbit missions. Testing under high irradiance, high temperature conditions over large areas poses design and logistic challenges, which have spurred innovation in steady state illumination. New test hardware of interest include a large area LED simulator capable of 6X AM0 string curre ...

Development and implementation of unique testing methods for the Solar Probe Plus array As a NASA mission to touch the sun Solar Probe Plus (SPP) reveals challenges previously not encountered in space solar panel design and testing. Simulating flight conditions require new testing methods and equipment which have been specifically developed for this unique PV application. Testing under high intensity, high temperature conditions over large areas poses design and logistic challenges, while testing cell performance degradation to a measurement level error of <1% involved fabrication of custom LED simulators.

Thermal design for high-temperature high-irradiance testing of space solar panel components Emcore has been performing High Intensity High Temperature (HIHT) tests on covered, interconnected cell (CIC) assemblies. End-of-life performance of spacecraft solar panels depends to a great extent on changes in the optical properties of the CICs coverglass adhesive during the mission. An important change in silicone coverglass adhesives is observed as degradation of short wavelength transmission, often called darkening or yellowing . This is understood to be driven by exposure to high intensity UV and by exposure to el ...

UV-exposure experiments for the Solar Probe Plus array NASA s Solar Probe Plus (SPP) will travel closer to the Sun than any previous spacecraft. During its 7-year, 24-orbit mission, SPP will make scientific measurements of the solar corona, reaching minimum perihelion at ∼9.5 solar radii (R Boca, Andreea; Blumenfeld, Philip; Crist, Kevin; De Zetter, Karen; Richards, Benjamin; Sarver, Charles; Sharps, Paul; Stall, Richard; Stan, Mark; Published by: Conference Record of the IEEE Photovoltaic Specialists Conference Published on: NASA; Photovoltaic cells; Probes; Radiation effects; Solar cell arrays; Sun; Temperature distribution; Parker Engineering |

High-irradiance high-temperature vacuum testing of the Solar Probe Plus array design The Solar Probe Plus (SPP) spacecraft will fly further into the Sun s corona than any previous mission, reaching a minimum perihelion at 9.5 solar radii from the center of the Sun. The solar arrays powering the spacecraft will operate under unusually high irradiances and temperatures. The array design, material choices, and necessary test facilities for SPP are therefore quite different from those used on traditional space panels. This paper gives an overview of the high-irradiance high-temperature vacuum (HIHT-Vac) reliabil ...

Array-design considerations for the solar probe plus mission The NASA Solar Probe Plus (SPP) mission will fly into and study the Sun s corona, reaching as close as 8.5 solar radii from the surface of the Sun. Power generation for the spacecraft will be provided by two solar array wings, which are being designed and built by Johns Hopkins University Applied Physics Laboratory and Emcore Photovoltaics. SPP will get closer to the Sun than any previous mission, and the solar array will therefore need to operate reliably under unusually high irradiances, temperatures, and angles of inciden ...
