Abstract

An advanced electronic load circuit was developed to characterise the current–voltage curves of seven metal-wrap-through triple-junction solar cells and four conventional quadruple-junction solar cells produced by AZUR SPACE GmbH. This solar cell experiment was launched aboard the EIVE nanosatellite in June 2023 and has been operational since October 2023. The evaluation of over 5,000 individual curves highlights the need for precise compensation of temperature, sun angle error, and solar flux effects. The corrected data show excellent agreement with ground measurements obtained from solar simulator testing of the same cells.
