Photocurrent transient analysis of a pristine Cu₂O film and three different Cu₂O/nanocarbon composites deposited with 0.5 C cm^–2 charge density. The measurements were performed in CO₂ saturated 0.1 M Na₂SO₄ solution at E = 0.05 V potential. A solar simulator was used employing a UV cutoff filter (<400 nm). Photocurrent normalization was performed using the relative surface area data in Table S1.
