“…Modeling photovoltaic module degradation is an important and evolving research area since it enables predicting module performance, identifying key degradation factors, and evaluating maintenance strategies [51]. Degradation models date back to at least 1982 with a capacitive approach to measure I-V curves in the field [51]. Numerous short and long-term degradation models have since been developed.…”

Photovoltaic (PV) modules, though reputed for reliability and long lifespans of 25-30 years, commonly experience gradual performance degradation influenced by varying environmental factors. This literature review explores the degradation of PV modules through in-depth analysis of failure modes, characterization techniques, analytical models, and mitigation strategies. A range of failure modes seen in PV modules are discussed, including interconnect breakage, cell cracks, metallization corrosion, delamination, ethylene-vinyl acetate (EVA) discoloration, Potential-Induced Degradation (PID), Light-Induced Degradation (LID), and other. Environmental stresses like temperature, humidity, ultraviolet (UV) radiation, and dust accumulation play significant roles in accelerating almost all degradation modes. Dust is a crucial factor in Middle East/North Africa (MENA) regions. Studying degradation modes under real-world conditions remains challenging, requiring extensive field testing to examine defect frequency, evolution rate, and impacts on energy production. PID is a major degradation mode requiring modeling and correction techniques to improve PV efficiency and lifespan. However, PID models are often limited to specific conditions, posing applicability challenges. Characterization methods like visual inspection, current-voltage (I-V),various imaging methods, and resonance ultrasonic vibrations (RUV) enable effective evaluation of degradation effects on module properties. Analytical models facilitate study of particular degradation modes and prediction of lifetimes under diverse conditions. Key factors influencing PV degradation include weather variations, materials quality, design parameters, PID, and hot spots. Protective coatings, encapsulation improvements, and module cleaning help mitigate degradation and prolong lifespan. A comprehensive understanding of mechanisms through integrated experimentation and modeling is critical for performance improvements. By reviewing major degradation phenomena, characterization techniques, analytical models, and mitigation strategies, this study promotes PV durability and sustainability. Significant knowledge gaps persist regarding module behavior under varied climate conditions and synergistic effects between different degradation mechanisms. Extensive field testing across diverse environments paired with advanced multiphysics modeling can provide valuable insights to guide technological enhancements for robust, long-lasting PV systems worldwide.

“…Establishing accelerating ageing tests with high predictive power is essential for a fast feedback loop that drives the development of new materials, interfaces and encapsulation strategies for stable PSCs. In silicon solar devices, indoor testing at higher temperatures under light has been systematically explored to accelerate the degradation and estimate their service life [4][5][6] . Unlike silicon 7 , perovskite has self-healing 8 characteristics attributed to its soft lattice nature, allowing for ion migration and defect repair 9 .…”

Halide perovskite is a material that shows great promise in producing renewable energy. It offers one of the most efficient forms of photovoltaics for large-scale production. However, while perovskite solar cell devices are more efficient than many established technologies, their long-term stability outdoors is still being determined. Most studies have tested the stability of perovskite solar cells by keeping them under continuous illumination at maximum power point tracking for hundreds to a few thousand hours. Increasing the temperature has been proposed to accelerate degradation and project data collected relatively quickly to years of outdoor operations. However, PSCs undergo extensive degradation recovery during the resting time in dark and transient dynamics during the illumination they experience in day-night cycling. Therefore, an ageing protocol based on maximum power point tracking under continuous illumination cannot enable quantitative prediction of outdoor performances. To address the challenge of predicting the outdoor stability of perovskite solar cells, we have demonstrated how ageing perovskite solar cells under light/dark cycling that reproduces outdoor functioning with controlled temperature and illumination conditions allows a predictive analysis. Our ageing protocol can accelerate the degradation of perovskite solar cells up to 46 times, i.e. 6 months of indoor testing can reproduce the standard 25 years of outdoor functioning. This result will speed up the studies of perovskite solar cells' stability and their commercialisation.
