Energy Industry

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 undergo 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, package loosening, or safety risks.

 

The performance of energy components depends not only on the material composition itself but is also greatly influenced by the quality of the multilayer structure, interface stability, and packaging protection capability. Therefore, clarifying how materials change during operation, where they begin to degrade, and the rate of degradation is key to whether lifespan prediction and design improvement can be carried out.

 

MA-tek assists energy companies in stages such as material development, process optimization, quality control of mass production, and failure tracing, providing high-resolution observation and lifetime testing simulation of structure, composition, optoelectronic and electrochemical behavior, establishing a traceable, quantifiable, and feedback design control mechanism.
