(FR) DISPOSITIFS PHOTOVOLTAÏQUES ET LEUR PROCÉDÉ DE FABRICATION
Abstract: front page image
(EN)A photovoltaic device is presented. The photovoltaic device includes a layer stack; and an absorber layer is disposed on the layer stack. The absorber layer comprises selenium, wherein an atomic concentration of selenium varies across a thickness of the absorber layer. The photovoltaic device is substantially free of a cadmium sulfide layer.
(FR)L'invention porte sur un dispositif photovoltaïque. Le dispositif photovoltaïque comprend un empilement de couches et une couche d'absorbeur disposée sur l'empilement de couches. La couche d'absorbeur comporte du sélénium, la concentration atomique du sélénium variant sur toute l'épaisseur de la couche d'absorbeur. Le dispositif photovoltaïque est sensiblement exempt d'une couche de sulfure de cadmium.
