1. An energy harvesting and self-cleaning system based on graphene aerogels, comprising:
a freeze-dried graphene aerogel; and
a layer of a metal collector that is sputtered directly on both sides of the same freeze-dried graphene aerogel by magnetron sputtering;
wherein the freeze-dried graphene aerogel with the metal collector is fixed on a side and a bottom of a substrate in series and/or parallel connection, and then is put into an electrolyte to get a target system.
