Abstract

We investigated the relationship between crystallinity, deep trap states and PEC performance of g-C3N4 photoelectrodes. Long-lived charge carriers were present in the more poorly crystalline samples, due to deeper trap states, which inversely correlated with photoelectrochemical performance. The charge diffusion length in a compact g-C3N4 film was determined to be ca. 1000 nm.
