Disclosed herein are optical stacks that are stable to light exposure by incorporating light-stabilizers and/or oxygen barriers.

Methods to incorporate silver nanowire-based transparent conductors in electronic devices

According to some embodiments, an organic device and method of forming an organic device are disclosed. A hybrid cathode layer is formed in stacked alignment with a substrate. The hybrid cathode layer includes a combination of a conductive nanowire and an electron-transport material. After forming the hybrid cathode layer, a photoactive layer is formed on a structure that includes the substrate and the hybrid cathode layer. After forming the photoactive layer, a hybrid anode layer that is separated from the hybrid cathode layer by the photoactive layer is formed. The hybrid anode layer includes a combination of a conductive nanowire and a hole-transporting material.

Organic solar module and/or fabrication method

Transparent conductors and methods of forming same are provided. A transparent conductor can include a nanostructure layer and a low sheet resistance grid disposed on a transfer film surface having an acceptable level of surface roughness. The presence of the low sheet resistance grid lowers the sheet resistance of the transparent conductor to an acceptable level. After release of the transparent conductor from the transfer film, the surface roughness of the transparent conductor will be at least comparable to the surface roughness of the transfer film.

Grid and nanostructure transparent conductor for low sheet resistance applications

The present disclosure relates to modifications to nanostructure based transparent conductors to achieve increased haze/light-scattering with different and tunable degrees of scattering, different materials, and different microstructures and nanostructures.

Methods of preparing photovoltaic modules, as well as related components, systems, and devices, are disclosed.

Methods of preparing photovoltaic modules

Atomic layer deposition in a roll-to-roll manufacturing environment is disclosed. At least a portion of a substrate from a first roll is disposed in a chamber. A first atomic layer deposition (ALD) half reaction is performed on the portion of the substrate while the portion is within the chamber. A subsequent ALD half reaction may be performed on the same portion of the substrate to form a layer of material. Multiple ALD sequences may be performed by passing the substrate through a sequence of ALD reaction chambers or by passing the substrate through one or more ALD reaction chambers in a continuous loop.

Roll-to-roll atomic layer deposition method and system

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 10to 10elements/m. 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.

Photovoltaic devices fabricated from nanostructured template

A method of manufacturing an electroluminescent device which has an anode and a cathode and arranged between the anode and the cathode a light emissive layer, also includes an anode protection layer which protects the anode against the effects of converting a precursor polymer to a semiconductive conjugated polymer which constitutes the light emissive layer. This has been found to increase the brightness and half-life of devices.

Electroluminescent devices with electrode protection

An organic light-emitting device, comprising: a substrate; a first conductive layer formed over the substrate; at least one layer of a light-emissive organic material formed over the first conductive layer; a barrier layer formed over the at least one organic layer which acts to protect the at least one layer of organic material; and a second conductive layer, preferably a patterned sputtered layer, formed over the barrier layer.

Organic light-emitting device and method of fabricating the same

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 10elements/mand about 10elements/m. 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 10/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.

Photovoltaic devices fabricated from insulating nanostructured template

One embodiment of this invention pertains to multiple encapsulated thin-film electronic devices. These encapsulated devices include a substrate and multiple thin-film electronic devices are on this substrate. Each of the multiple thin-film electronic devices has an active area. The encapsulated devices also include an encapsulation layer that is on the substrate and this encapsulation layer has multiple holes and these multiple holes are over the active areas of the multiple thin-film electronic devices. The encapsulated devices also include multiple substantially flat encapsulation pieces that are on the encapsulation layer and these multiple substantially flat encapsulation pieces cover the multiple holes of the encapsulation layer. An absorbent material is not attached to any of the substantially flat encapsulation pieces.

Encapsulation of thin-film electronic devices

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. In another embodiment, the output light chromaticity of the panel is controlled either by users or by light sensors.
