A photovoltaic device operable to convert light to electricity, comprising a substrate, a plurality of structures essentially perpendicular to the substrate, one or more recesses between the structures, each recess having a planar mirror on a bottom wall thereof. The structures have p-n or p-i-n junctions for converting light into electricity. The planar mirrors function as an electrode and can reflect light incident thereon back to the structures to be converted into electricity. L'invention porte sur un dispositif photovoltaïque qui est capable de convertir la lumière en électricité et qui comporte un substrat, une pluralité de structures sensiblement perpendiculaires au substrat, un ou plusieurs renfoncements entre les structures, chaque renfoncement ayant un miroir plan sur une paroi de fond. Les structures ont des jonctions p-n ou p-i-n pour convertir la lumière en électricité. Les miroirs plans fonctionnent comme une électrode et peuvent réfléchir la lumière incidente vers les structures pour qu'elle soit convertie en électricité.
