ABSTRACT:
A solid state energy conversion device and method of making is disclosed for converting energy between electromagnetic and electrical energy. The solid state energy conversion device comprises a wide bandgap semiconductor material having a first doped region. A thermal energy beam is directed onto the first doped region of the wide bandgap semiconductor material in the presence of a doping gas for converting a portion of the first doped region into a second doped region in the wide bandgap semiconductor material. A first and a second Ohmic contact are applied to the first and the second doped regions of the wide bandgap semiconductor material. In one embodiment, the solid state energy conversion device operates as a light emitting device to produce electromagnetic radiation upon the application of electrical power to the first and second Ohmic contacts. In another embodiment, the solid state energy conversion device operates as a photovoltaic device to produce electrical power between the first and second Ohmic contacts upon the application of electromagnetic radiation.
