Comparison of Semiconducting and Metallic Carbon Nanotubes Incorporating In2S3/In2O3 Photoelectrochemical Cells

[摘要] We fabricate photoelectrochemical cells (PECs) using In2S3/In2O3 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.
