What's Happening?
Recent advancements in the use of X-ray photoelectron spectroscopy (XPS) have improved the understanding of photoactive semiconductors, which are crucial for clean technologies like photovoltaics and photocatalysis. XPS allows for the detection of impurities and surface deterioration in semiconductors during production, and monitors changes in the oxidation state of the semiconductor's surface due to environmental exposure. This deeper insight into the surface chemical state aids in elucidating the mechanisms of photocatalytic reactions and improving semiconductor stability, ultimately enhancing solar energy conversion efficiency.
