Patent number: 7605327Abstract: Photovoltaic devices, such as solar cells, and methods for their manufacture are disclosed. A device may be characterized by an architecture having a nanostructured template made from an n-type first charge transfer material with template elements between about 1 nm and about 500 nm in diameter with about 1012 to 1016 elements/m2. A p-type second charge-transfer material optionally coats the walls of the template elements leaving behind additional space. A p-type third charge-transfer material fills the additional space volumetrically interdigitating with the second charge transfer material.Type: GrantFiled: February 2, 2004Date of Patent: October 20, 2009Assignee: Nanosolar, Inc.Inventors: Martin R.

Publication number: 20090178702Abstract: A method for manufacturing optoelectronic devices is disclosed. A layered structure may be formed with a plurality of layers including a bottom electrode layer, a top electrode layer, and one or more active layers between the top and bottom electrode layers. The layered structure is divided into one or more separate device module sections by cutting through one or more of the layers of the layered structure. At least one of the layers is an unpatterned layer at the time of cutting. Each of the resulting device module sections generally includes a portion of the active layer disposed between portions of the top and bottom electrode layers. An edge of a device section may optionally be protected against undesired electrical contact between two or more of the bottom electrode, top electrode and active layer portions.Type: ApplicationFiled: October 4, 2008Publication date: July 16, 2009Inventor: Karl Pichler

Patent number: 7319440Abstract: A novel OLED light source and method for controlling said OLED light source panel are disclosed wherein said light source is constructed such that active areas are segmented and said segments are separately addressable. In one embodiment, the segments are a series of RGB lines or stripes and the control unit may separately drive each individual stripe or may drive all separate color lines or may drive separate lines within a given region on the panel. In another embodiment, the stripes of the panel are connected to control lines that are either current limited or have a fuse that serves to obviate a current runaway condition on the panel.

Publication number: 20070085870Abstract: A system and method is presented for measuring the volume of an ink-jet droplet or the relative volumes of a plurality of ink-jet droplets using their electrical properties. In a preferred embodiment a single small capacitor or an array of capacitors is used to measure the dielectric properties of ink-jet droplets and the absolute drop volumes are derived. In an alternative preferred embodiment the relative differences in drop volumes are determined. A feedback circuit, such as one using lock-in technique, may be used to automatically adjust subsequent drop volumes.Type: ApplicationFiled: September 27, 2006Publication date: April 19, 2007Applicant: OSRAM OPTO SEMICONDUCTORS GMBHInventors: Matthias Stoessel, Karl Pichler

Patent number: 7078726Abstract: In one embodiment of the invention, a first absorbing layer is on a substrate and/or a second absorbing layer is on a heat-activated adhesive. If the IR source that supplies IR radiation is present on the substrate-side, then the absorption percentage of the substrate is less than the absorption percentage of the first absorbing layer if present and less than the absorption percentage of the second absorbing layer if present. If the IR source that supplies IR radiation is present on the “encapsulation cover”-side, then the absorption percentage of the encapsulation cover is less than the absorption percentage of the first absorbing layer if present and less than an absorption percentage of the second absorbing layer if present. The substrate and the encapsulation cover have a low thermal conductivity.Type: GrantFiled: September 9, 2004Date of Patent: July 18, 2006Assignee: Osram Opto Semiconductors GmbHInventors: Karl Pichler, Kyle D.

Patent number: 6946597Abstract: 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.Type: GrantFiled: May 21, 2003Date of Patent: September 20, 2005Assignee: Nanosular, Inc.Inventors: Brian M.
