Abstract:
Photovoltaic devices such as solar cells, hybrid solar cell-batteries, and other such devices may include an active layer disposed between two electrodes, the active layer having perovskite material and other material such as mesoporous material, interfacial layers, thin-coat interfacial layers, and combinations thereof. The perovskite material may be photoactive. The perovskite material may be disposed between two or more other materials in the photovoltaic device. Inclusion of these materials in various arrangements within an active layer of a photovoltaic device may improve device performance. Other materials may be included to further improve device performance, such as, for example: additional perovskites, and additional interfacial layers.

Claim (Index 50):
A photovoltaic device comprising:\n a first electrode; a second electrode; and an active layer disposed at least partially between the first and second electrodes, the active layer comprising an interfacial layer, and a perovskite material layer, wherein the perovskite material has the formula CMX3 and the perovskite material layer is disposed adjacent to and in contact with the interfacial layer;\n wherein C comprises formamidinium and one or more cations selected from the group consisting of Group 1 metals, Group 2 metals, methyl ammonium, guanidinium, ethene tetramine; \n wherein M comprises Cu and Fe; and \n wherein X comprises one or more anions each selected from the group consisting of halides, sulfides, selenides, and combinations thereof.
