A photovoltaic device comprising an array of elongate reflector elements mounted substantially parallel to one another and transversely spaced in series, at least one of the reflector elements having an elongate concave reflective surface to reflect incident solar radiation towards a forward adjacent reflector element in the array. The at least one reflector element includes a photovoltaic receptor mounted on the reflector element by a mounting arrangement to receive reflected solar radiation from a rearward adjacent reflector element. The reflector element also includes a heat sink in heat transfer relationship with the photovoltaic receptor, thermally isolating the photovoltaic receptor, at least partially, from the reflector element.
