With the accelerated development of net-zero carbon emissions, energy storage, and distributed power systems, the reliability requirements for energy components such as solar cells, lithium batteries, and hydrogen fuel cells have significantly increased. These components experience complex environmental factors during operation, including electrochemical reactions, thermal cycling, humidity exposure, and material migration, which can easily lead to interface aging, active layer degradation, packaging loosening, or safety risks.
The performance of energy components is not only determined by the material composition itself but is also greatly influenced by the quality of multilayer structures, interface stability, and encapsulation protection capabilities. Therefore, clarifying how materials change during operation, where degradation begins, and the rate of degradation is key to whether lifetime prediction and design improvement can be carried out.
MA-tek assists energy companies in stages such as material development, process optimization, product quality control, and failure analysis, providing high-resolution observations and lifetime testing simulations of structure, composition, optoelectronic, and electrochemical behavior, establishing a traceable, quantifiable, and feedback design control mechanism.
