Consistent and repeatable baseline characterization of the temperature-dependent performances of CI(G)S PV modules is challenging due to their transient metastable behavior. We compare state-of-the-art measurements using pulsed simulated sunlight to outdoor measurements and discuss the trade-offs. Indoor measurement results taken from commercial modules in their dark-soaked state are compared to measurements taken in their light-soaked state. We find that measured temperature-dependent performance parameters of CI(G)S PV modules are highly dependent on both their metastable state, the measurement process, and the specific CI(G)S PV module under evaluation. In spite of metastable PV module measurement challenges, we demonstrate that properly designed indoor measurement techniques produce values that are in good agreement with advanced outdoor measurement methods.
