Abstract
A method of making a micron gap thermal photovoltaic device wherein at least one standoff is formed on a photovoltaic substrate, a sacrificial layer is deposited on the photovoltaic substrate and about the standoff, an emitter is attached to the standoff and has a lower planar surface separated from the photovoltaic substrate by the sacrificial layer, and the sacrificial layer is removed to form a sub-micron gap between the photovoltaic substrate and the lower planar surface of the emitter.
