Nanostructured transparent conducting electrode.

Today's pick up in solar cell / photovoltaic patents.
7,594,982 (Sep. 29 2009)
Nanostructured transparent conducting electrode.
MartinR. Roscheisen and BrianM. Sager
Nanosolar, Inc.
abstract:
Transparent conducting electrodes, methods for manufacturing such conducting electrodes, optoelectronic devices incorporating such transparent electrodes and methods for making such optoelectronic devices and solar power generation systems incorporating such electrodes are disclosed. Nanostructured transparent conducting electrodes may include a nano-architected porous film having a network of ordered interconnected pores and an electrically conductive material that substantially fills the pores. The nano-architected porous film may be disposed on a layer of transparent conducting material. The electrode may include a substrate (e.g., glass or polymer) and the layer of transparent conducting material may be disposed between the substrate and the nano-architected porous film. Nanostructured transparent conducting electrodes may be fabricated by forming a nano-architected porous film, e.g., by surfactant temptation, on a layer of transparent conducting material and substantially filling the pores in the nano-architected porous film with an electrically conductive material, e.g., by electrodeposition. Optoelectronic devices may incorporate one or more nanostructured transparent conducting electrodes in electrical contact with an active layer. Such devices may be made by fabricating a first electrode and disposing an active layer between the first electrode and a second electrode, one of which is a nanostructured transparent conducting electrode.

Optoelectronic device and fabrication method

Today's pick up in solar cell / photovoltaic patents.
7,291,782 (Nov. 06 2007)
Optoelectronic device and fabrication method.
BrianM. Sager, MartinR. Roscheisen, Klaus Petritsch, Greg Smestad, Jacqueline Fidanza, GregoryA. Miller and Dong Yu
Nanosolar, Inc.
abstract:
Charge-splitting networks, optoelectronic devices, methods for making optoelectronic devices, power generation systems utilizing such devices and method for making charge-splitting networks are disclosed. An optoelectronic device may include a porous nano-architected (e.g., surfactant-templated) film having interconnected pores that are accessible from both the underlying and overlying layers. A pore-filling material substantially fills the pores. The interconnected pores have diameters of about 1-100 nm and are distributed in a substantially uniform fashion with neighboring pores separated by a distance of about 1-100 nm. The nano-architected porous film and the pore-filling, material have complementary charge-transfer properties with respect to each other, i.e., one is an electron-acceptor and the other is a hole-acceptor. The nano-architected porous, film may be formed on a substrate by a surfactant temptation technique such as evaporation-induced self-assembly. A solar power generation system may include an array of such optoelectronic devices in the form of photovoltaic cells with one or more cells in the array having one or more porous charge-splitting networks disposed between an electron-accepting electrode and a hole-accepting electrode.

Photovoltaic devices fabricated by growth from porous template.

Today's pick up in solar cell / photovoltaic patents.
6,946,597 (Sep. 20 2005)
Photovoltaic devices fabricated by growth from porous template.
BrianM. Sager, MartinR. Roscheisen, Klus Petritsch, Karl Pichler, Jacqueline Fidanza and Dong Yu
Nanosular, Inc.
abstract:
Photovoltaic devices, such as solar cells, and methods for their manufacture are disclosed. A device may be characterized by an architecture where two more materials having different electron affinities are regularly arrayed such that their presence alternates within distances of between about 1 nm and about 100 nm. The materials are present in a matrix based on a porous template with an array of template pores. The porous template is formed by anodizing a layer of metal. A photovoltaic device may include such a porous template disposed between a base electrode and a transparent conducting electrode. A first charge-transfer material fills the template pores, A second (complementary) charge-transfer material fills additional space not occupied by the first charge-transfer material.
