Abstract:
A photovoltaic device comprising a supporting substrate having on its surface a heterolamellar film having one or more charge donating layers and one or more charge accepting layers, each layer comprising(i) a plurality of a complex of the formula:[(Y.sup.1 O.sub.3 --Z--Y.sup.2 O.sub.3)Me.sup.Y ].sub.k.k*p(X.sup.q-)whereineach of Y.sup.1 and Y.sup.2, independently of the other, is phosphorus or arsenic;Z is a divalent group which reversibly forms a stable reduced form and stable oxidized form;X is an anion;Me.sup.Y is Me.sup.1.sub.n W.sub.m, whereMe.sup.1 is a divalent, trivalent, or tetravalent metal of Group III, IVA, or IVB having an atomic number of at least 21 or a lanthanide;W is an anion;n is 1, 2, or 3;m is 0, 1, 2, 3, or 4;k has a value of from 1 to about 250;p has a value of 0, 1, 2, or 3; andq is the charge on X,wherein each of Y.sup.1, Y.sup.2, Z, and Me.sup.1 may be different for each layer;ii) one or more charge generator layers between said one or more charge donating layers and one or more charge accepting layers;wherein said film is bound to said substrate through a linking means.
