Photogenerated charge separation
WebSpatial separation of photogenerated electrons and holes has been evidently demonstrated to take place between (040) and (200) facets of BiVO 4 nanocrystals, on which the charge separation efficiency is verified to definitely depend on the facet proportion of (040)/ (200). Further theoretical simulation reveals that the matching degree of ... WebMar 13, 2024 · The efficiency of converting light energy to chemical energy is equal to the product of the efficiencies of the following three processes: light capture, photogenerated charge separation and migration, and the high-efficiency surface catalytic reaction. How to achieve efficient synergy of these three processes is a very critical scientific problem.
