Abstract

A thermoelectronic energy conversion device (100) comprises an electron emitter (10), which is adapted for a temperature-dependent release of electrons (1), an electron collector (20), which is adapted for a collection of the electrons (1), wherein the electron collector (20) and the electron emitter (10) are spaced from each other by a gap (2), and a gate electrode (30), which is arranged between the electron emitter (10) and the electron collector (20), wherein the gate electrode (30) is adapted for subjecting the electrons (1) in the gap (2) to an electrical potential, wherein the gate electrode (30) comprises at least one membrane-shaped, electrically conductive or semiconductive electrode layer (31), which is at least partially transparent for the electrons (1). The electrode layer (31) is e. g. graphene or a similar two-dimensional material. Furthermore, a power source device including at least one energy conversion device and a method of converting energy using the thermoelectronic energy converter device (100) are described.
