Proposed is a method for producing an ambient energy converter comprising a plate-like carrier substrate, which consists of a first conductor material, as a first electrode, and comprising a layered structure, which is arranged on said first electrode and which has a layer of ferroelectric material and a layer of a second conductor material that differs from the first conductor material, as a second electrode. The two conductor materials have different concentrations of free electrons. The ferroelectric material comprises one or more ferroelectric semiconductors. Ferroelectric semiconductors that are used as ferroelectric material are selected from the list comprising sodium nitrite, semiconductor ceramics based on barium titanate, lithium niobate, potassium niobate, lead titanate, etc. The method comprises the following method steps: - providing a plate, which consists of the conductor material provided for the first electrode, as the carrier substrate, - subjecting the carrier substrate to at least one surface treatment, - applying the layer of ferroelectric material (FE layer) to a side of the carrier substrate which is intended as a front side, - masking at least the edges of the FE layer on the front side of the carrier substrate, leaving free at least one section situated within the edges of the FE layer, and - applying the conductor material provided for the second electrode to the section left free by the masking.

Abrégé

A method of manufacturing an ambient energy converter that includes a supporting substrate of a first conductor material as a first electrode, a layer of ferroelectric material, and a layer of a second conductor material as a second electrode. The two conductor materials have different concentrations of free electrons. The ferroelectric material includes one or more ferroelectric semiconductors. The method includes providing a plate of the conductor material for the first electrode as a supporting substrate, subjecting the carrier substrate to a surface treatment, depositing the layer of ferroelectric material (BTO layer) on a front side of the carrier substrate, masking the edges of the BTO layer on the front side of the carrier substrate while leaving at least one portion located within the edges of the BTO layer free, and applying the conductor material intended for the second electrode to the area kept free of masking.
