Graphite-protected organic photoactive layer for direct solar hydrogen generation
Nature Energy, Published online: 25 March 2025; doi:10.1038/s41560-025-01737-5Performance issues have limited the use of organic photoactive materials in direct solar water-splitting devices. Now, anodes containing a single-junction organic bulk heterojunction solar cell protected by a graphite sheet functionalized with an Earth-abundant electrocatalyst achieve a high water oxidation photocurrent density and days-long operational stability. Moreover, tandem devices achieve unassisted solar water splitting.
