In-situ Determination of Moisture Diffusion Properties of PV Module Encapsulants Using Digital Humidity Sensors
Jankovec, M.; Annigoni, E.; Ballif, C.; Topic, M. (2018)We conducted a long-term (>6500 h) in-situ PV module humidity monitoring experiment, where digital humidity sensors encapsulated in different encapsulants (EVA, TPO, POE and ionomer) were exposed to different humidity ... -
Modeling Potential-Induced Degradation (PID) of Field-Exposed Crystalline Silicon Solar PV Modules: Focus on a Regeneration Term
Annigoni, E.; Virtuani, A.; Sculati-Meillaud, F.; Ballif, C. (2017)In this work, we further elaborate a model that was previously presented to simulate the effect of potential-induced degradation (PID) on the performance of field-exposed modules. We add to the predictive model a term aimed ... -
Quantifying and Modeling the Impact of Interconnection Failures on the Electrical Performance of Crystalline Silicon Photovoltaic Modules
Annigoni, E.; Virtuani, A.; Levrat, J.; Faes, A.; Despeisse, M.; Ballif, C.; et al. (2018)We present an electrical model developed with LT SPICE that simulates the performance of a string of cells with disconnections in the electrical circuit. In a previous contribution, we quantified experimentally how the ... -
Quantifying and modeling the impact of interconnection failures on the electrical performance of crystalline silicon photovoltaic modules
Annigoni, E.; Virtuani, A.; Levrat, J.; Faes, A.; Sculati-Meillaud, F.; Despeisse, M.; et al. (2019)Failures in the metallic interconnections are among the main degradation modes for photovoltaic modules. Fatigue accumulation due to thermomechanical stresses can result in deterioration of the solder joints or in broken ...
