I–V curves measured at bulk CuSCN (a) electrodeposited without RB and porous crystalline CuSCN (b) electrodeposited with 1.0 mM RB and RB subsequently removed by DMA treatment, measured in the dark (hashed lines) and under illumination (solid lines) with visible light (100 mW cm^–2) generated by a 500 W Xe lamp equipped with UV and IR cutoff filters. The CuSCN films were sensitized by readsorbing RB by soaking in a 0.5 mM RB aqueous solution for 1 h. The electrolyte was a deaerated aqueous solution of 0.1 M methylviologen chloride.
