photocatalytic activity

initialism: PCA
https://doi.org/10.1351/goldbook.14042
Number of entities (product) formed in a photocatalytic process (alternatively the number of reactant entities disappearing) divided by the number of photons absorbed by the photocatalyst at one single wavelength or within a defined wavelength range. For one wavelength it has the same meaning as quantum yield, whereas within a defined wavelength range it has the same meaning as quantum efficiency.
Note: This quantity has a well-defined meaning only when the reaction conditions are also stated and the results reported in terms of the initial conditions.
