Electric power generator containing an active organic material

An electric power generator (EPG) comprising:

• at least one electrode,
• at least one current collector,
• at least one active organic material interposed between the at least one electrode and the least one current collector, and
• at least one oxygen-containing compound layer,
• wherein said at least one active organic material comprises at least one organic polymer obtainable by heating in a range of temperature of from 60° C. to 160° C. for a time from 1 hour to 3 hours a mixture comprising from 5 weight % to 70 weight % of polyvinyl alcohol and from 30 weight % to 95 weight % of at least one glycol selected from the group consisting of ethylene glycol and propylene glycol with respect to the total weight of the at least one organic polymer, and
• wherein the at least one oxygen-containing compound layer is in contact to said at least one active organic material and
• wherein the at least oxygen-containing compound layer is in contact with the at least one current collector.
