001044678 520__ $$aThe advancement of flexible photovoltaic (PV) technologies needs the establishment of standardized protocols for their characterization, particularly concerning mechanical performance and durability. Here we show newly proposed standard procedures such as ISOS-B, ISOS-M and a new protocol for measuring PCE over 1000 bending cycles under 1% strain, which aim to complete existing guidelines such as IEC 61215 and IEC 61646.ISOS-B focus on bending stress testing. This protocol is crucial for accurately assessing the mechanical stability of flexible PV devices, which can exhibit negligible degradation even under extreme bending conditions. ISOS-M addresses mechanical and long-term stability under various environmental conditions, suggesting tests in controlled ambient conditions to isolate the effects of mechanical stress from other environmental factors. This is essential for understanding how flexible devices perform over time, especially when exposed to real-world conditions. We further evaluate the need to measure the mechanical stability of a flexible device independently from the thickness and on the material properties of the substrate, by calculating its strain and defining a new figure of merit called fatigue factor. The introduction of a fatigue factor quantifies the mechanical performance of flexible PV devices, facilitating objective comparisons of durability and efficiency. This factor allows researchers to evaluate the relationship between mechanical stress and electrical performance. In conclusion, by improving upon existing IEC guidelines, these standards provide a robust framework for evaluating the mechanical and environmental performance of flexible PV technologies, ultimately contributing to their commercialization and integration into different applications. The integration of these standardized procedures fosters advancements in flexible photovoltaics, leading to improved device reliability and performance in practical applications.
