The present invention provides for an electroactive device having a first conductive layer, a second conductive layer, and one or more electroactive layers sandwiched between the first and second conductive layers. One or more adjacent layers of the electroactive device may include a physical separation between a first portion and a second portion of the adjacent layers, the physical separation defining a respective tapered sidewall of each of the first and second portions. The one or more adjacent layers may include one of the first and second conductive layers. The remaining layers of the electroactive device may be formed over the physical separation of the one or more adjacent layers. The remaining layers may include the other of the first and second conductive layers.

Methods for producing lower electrical isolation in electrochromic films

Several of the films that comprise various energy producing or control devices, for example, electrochromic devices, lithium batteries, and photovoltaic cells, are sensitive to moisture in some way. They may be especially vulnerable to moisture at particular stages during their fabrication. It may also be highly desirable during fabrication to be able to wash particulates from the surface. The particulates may be generated some aspect of the fabrication process, or they may arise from the environment in which the fabrication takes place. This invention shows ways to remove said particles from the surface without incurring the damage associated with typical washing processes, resulting in higher manufacturing yields and better device performance.

Particle removal from electrochromic films using non-aqueous fluids

The disclosure is directed to a cutting process involving: (a) creating a starter crack using a scribe wheel, (b) application of laser or electrothermal heating, and (c) subsequent cooling from a gas or an aerosol jet, as the laser beam and cooling jet move along the desired cutting line. The cutting process can be implemented for cutting a glass panel or other substrate into a plurality of smaller panels. The starter crack may be created on any of the smaller panels within about 10 mm to about 20 mm from the corner of the smaller panel.

One object of the present invention is to provide an electrochromic device having improved insulating film structure to reduce electrical leakage. The improved structure includes a lower conductive layer, upper conductive layer, an electrochromic electrode layer, a counter electrode layer, and at least one ion-conductor layer sandwiched between the electrochromic electrode layer and the counter electrode layer. The lower conductive layer and the electrochromic electrode layer are scribed and the gap formed from the scribing is filled with the layers formed above the electrochromic electrode layer. In some aspects, the ion-conductor layer is also scribed with the lower conductor and electrochromic electrode layers and the gap formed from the scribing is filled with the layers formed above the ion-conductor layer. In further aspects, the insulating film may include one or more buffer layers formed above an ion-conductor layer, further separating the upper conductive layer from the lower conductive layer.

Laser cuts to reduce electrical leakage

An apparatus for repair of a defect in an electronic energy control device may include a position indicating means for indicating a position at which to fixedly position a mounting unit relative to a portion of an electronic energy control device including a defect to be repaired, where the device is fixed in position. An imaging and repair assembly of the apparatus has an optical imaging range and a laser repair range. When the mounting unit is mounted to a support surface to fixedly position the mounting unit at the position indicated by the position indicating means and the imaging and repair assembly is attached to the mounting unit, the portion of the electronic energy control device is within the imaging range and the repair range.

Apparatus and method for repair of defects in an electronic energy control or display device

A process for fabricating of an article by exposing a photoreactive composition to light under multiphoton absorption conditions. The light passes through an optical system having a final optical element having a numeric aperture in a range of from 0.65 to 1.25, inclusive.

A refractive index grating comprising an optical fiber having at least one radiation-sensitized portion, in a longitudinal section of the optical fiber, containing a periodic variation of refractive index. The refractive index grating has an initial magnitude that changes no more than two percent after conditioning at a temperature of 300&#xb0; C. for a time of ten minutes.

Sensitized optical fiber method and article

Method of fabricating an optical element. A photodefinable composition is provided that includes (i) a hydrophobic, photodefinable polymer, said photodefinable polymer having a glass transition temperature in the cured state of at least about 80&#xb0; C.; and (ii) a multiphoton photoinitiator system comprising at least one multiphoton photosensitizer and preferably at least one phtoinitiator that is capable of being photosensitized by the photosensitizer. One or more portions of the composition are imagewise exposed to the electromagnetic energy under conditions effective to photodefinably form at least a portion of a three-dimensional optical element.

Microfabrication of organic optical elements

The invention relates to inducing a refractive index change in the glass substrate of a polymer coated optical device by using a high numeric aperture lens to focus a femtosecond laser beam through the polymeric coating to the substrate without damaging the polymeric coating.

An apparatus for irradiating an article, particularly a multi-layer article, with electron beam radiation is provided. The apparatus contains a window having a short unit path length and allows for controlled irradiation of an article such that upper portions of the article receive significantly higher electron beam dosages than lower portions of the article. Such differential dosage allows for modification of an article comprising a coating composition that can be modified by electron beam irradiation on a substrate that is vulnerable to degradation from electron beam radiation. A method of irradiating an article with electron beams, and products manufactured using the apparatus and method of the invention, are also disclosed.
