    摘要: Photovoltaic devices, such as solar cells, and methods for their manufacture are disclosed. A device may be characterized by an architecture with an inorganic insulating nanostructured template having template elements between about 1 nm and about 500 nm in diameter with a elements density of between about 1012 elements/m2 and about 1016 elements/m2. A first charge-transfer material coats the walls of the template elements leaving behind additional space. A second charge-transfer material fills the additional space such that the first and second charge-transfer materials are volumetrically interdigitated. At least one charge transfer material has an absorbance of greater than about 103/cm. The first and second charge-transfer materials have complementary charge transfer properties with respect to each other. A lowest unoccupied molecular orbital (LUMO) or conduction band of the first charge-transfer material is offset from a LUMO or conduction band of the second charge-transfer material by greater than about 0.2 eV. An electrically conductive material may optionally be disposed between the nanostructured template and the first charge-transfer material.

    摘要: Methods and devices are provided for forming an absorber layer. In one embodiment, a method is provided comprising of depositing a solution on a substrate to form a precursor layer. The solution comprises of at least one polar solvent, at least one binder, and at least one Group IB and/or IIIA hydroxide. The precursor layer is processed in one or more steps to form a photovoltaic absorber layer. In one embodiment, the absorber layer may be created by processing the precursor layer into a solid film and then thermally reacting the solid film in an atmosphere containing at least an element of Group VIA of the Periodic Table to form the photovoltaic absorber layer. Optionally, the absorber layer may be processed by thermal reaction of the precursor layer in an atmosphere containing at least an element of Group VIA of the Periodic Table to form the photovoltaic absorber layer.
