Light assisted rechargeable batteries: a proof of concept with BODIPY derivatives acting as a combined photosensitizer and electrical storage unit

Photosensitive dye based boron dipyrromethene polymer has been investigated in the scope of photo-assisted rechargeable batteries. Under visible light, a 0.8 V gain has been observed for the BODIPY moiety reduction process. The light energy contributes advantageously to the charge yield of the organic material potentially involved in lithium batteries.
