Abstract
A photovoltaic device includes a substrate having at least two surfaces and a multilayered film disposed on at least a portion of at least one surface of the substrate. Elongated nanostructures are disposed on the multilayered film. The device incorporates a top layer of the multilayered film contacting the elongated nanostructures that is a tunnel junction. The device has at least one layer deposited over the elongated nanostructures defining a portion of a photoactive junction. A solar panel includes at least one photovoltaic device. The solar panel isolates each such devices from its surrounding atmospheric environment and permits the generation of electrical power.
Claims21
A photovoltaic device comprising:
- a substrate having two surfaces;
- a multilayered film disposed on at least one of the at least two surfaces of the substrate;
- the multilayered film comprising (a) at least one layer that is part of a first photoactive junction, and (b) a first tunnel junction layer disposed over the first photoactive junction;
- a plurality of elongated nanostructures disposed on the first tunnel junction layer of the multilayered film, wherein the first tunnel junction layer is located between the substrate and the nanostructures;
- and
- a conformal layer disposed on the nanostructures, wherein the conformal layer forms a part of a second photoactive junction;
- the second photoactive junction separated from the first photoactive junction by the first tunnel junction layer.
