We fabricate photoelectrochemical cells ( PECs ) using In 2 S 3 / In 2 O 3 double‐layer composite as a working electrode in the presence of single‐walled carbon nanotubes ( SWCNTs ). Simple solution methods, such as spray‐coating and chemical bath deposition, were used to assemble each layer in the PECs . We apply pristine SWCNTs , semiconducting SWCNTs (s‐ SWCNTs ), and metallic SWCNTs (m‐ SWCNTs ) to the PECs , and measure their solar performances, incident photon to charge carrier efficiency, and electro‐impedance spectra. Field emission is also measured to explain the enhanced electric field of each cell.
