A, B The photocurrent density (I-V) curves of different array films to evaluate their photoelectric properties. C, D The EIS Nyquist plots. TNTs (a), CdS/TNTs (b), Ag2S/TNTs (c), Ag2S/CdS/TNTs by SSM (d), and Ag2S/CdS/TNTs via SILAR (e). All the QDs are deposited 6 cycles (A and C), Ag2S/CdS/TNTs by SSM at different deposition cycles (B and D), the number in the parenthesis is the deposition cycles. The experiments were carried out under irradiation of visible light (λ > 420 nm).
