As countries face the pressure of delivering stronger climate commitments outlined in their Nationally Determined Contributions (NDCs), the role of advancing sustainable technologies becomes increasingly critical. Kate Vanderburgh from Thermo Fisher Scientific highlights how electron microscopy (EM) drives material innovation to support low-carbon technologies combating climate change. EM's nanoscale resolution aids in the development of renewable energy materials like semiconductors for solar efficiency and advanced composites for wind turbine durability. Additionally, breakthroughs in electrodes and electrolytes for energy storage benefit from EM's detailed characterization of material structures. EM's applications extend to solar panel materials, where it reveals defects and grain boundaries for optimizing efficiency and stability. In battery materials, EM identifies weaknesses at the nanoscale, enhancing lifespan and safety by detecting defects like dendrite formation. Furthermore, hydrogen technology benefits from EM's analysis of structural features and elemental distributions for efficient hydrogen uptake and release. Thermo Fisher's ChemiSEM offers a unified solution for precise structure and compositional analysis, integrating SEM imaging and EDS analysis. This streamlined approach provides faster results, accurate quantification, and real-time analysis of material phases, reducing redundancies in the analysis process. Case studies, such as the Ag/Zn Si photovoltaic material, demonstrate how EM techniques can enhance solar cell technology through micro and nanoscale examination, showcasing the impact of advanced microscopy on accelerating sustainable innovation.
