For the first time influence of humidity on photoconductivity transient characteristics are studied for antimony sulfoiodide (SbSI) single nanowires. While negative photoconductivity is observed for SbSI gel, made up of large quantity of nanowires, only the positive effect occurs for SbSI single nanowires. Photoconductivity current response on switching on and off illumination in moist N₂ represents so-called hook anomaly.
