A The I-t curves of the five films under intermittent illumination of UV and visible light (320–800 nm) at bias voltages of 0 V vs. reference electrode Hg/Hg2Cl2. B The I-t curves of the five different anodes under intermittent illumination of visible light (λ > 420 nm). C The photocurrent response of the array films of Ag2S/CdS/TNTs by SSM with different deposition cycles. D The photocurrent-response of pure TNTs to the incident light with various wavelengths is principally active in the UV light region. TNTs (a), CdS/TNTs (b), Ag2S/TNTs (c), Ag2S/CdS/TNTs by SSM (d), and Ag2S/CdS/TNTs via SILAR (e)
