A photovoltaic structure includes, from bottom to top, a conductive substrate, at least one electrical isolation layer, and a patterned conductive material layer. The patterned conductive material layer includes at least one solar concentrator receiver plate configured to mount a photovoltaic concentrator cells and at least one metallic wiring structure. The at least one electrical isolation layer can include a stack of an electrically insulating metal-containing compound layer and an organic or inorganic dielectric material that provides thermal conduction and electrical isolation. The at least one solar concentrator receiver plate can be thicker than the at least one metallic wiring structure so as to provide enhanced thermal spreading and conduction through the at least one electrical isolation layer and into the conductive substrate.
