Nanowire morphology control in Sb metal-derived antimony selenide photocathodes for solar water splitting

Key Points

• The aim is to enhance the performance of antimony selenide photocathodes for solar water splitting by controlling nanowire morphology.
• Tuning substrate temperature during Sb metal deposition
• Fabricating Sb₂Se₃ photocathodes
• Measuring photocathode performance and charge recombination effects
• Thinner nanorods significantly reduce charge recombination
• Enhanced photocurrent achieved by restricting charge transport in the hk 0 direction
