Performance, Operational Data and Stability of Commercial CIGS Thin-Film PV Modules in BIPV Systems
Year: 2025
Type: conference-paper
Abstract: This work presents long-term operational data of CIGS-based PV systems across varying levels of integration and environmental exposure. Environmental data including module temperatures, air flow, surface moisture, and relative humidity of building integrated PV installations are shown. Different module orientations in the context of the usage of module optimizers were analysed. Performance evaluations of commercial and R&D systems confirm the long-term stability of CIGS PV modules with no or minimal degradation observed over more than a decade, including the latest generation of CIGS PV modules featuring gallium-rich absorbers, sodium post deposition treatment, and a dry ZnOS buffer.
