Abstract:
In a process for manufacturing a light-modulation device, a composite film, sheet or strip is manufactured by known techniques, in particular extrusion, lamination, calandering, and coating. At least one layer of electrolytic material is applied to a counter electrode in the form of a preferably flexible film, sheet or strip or equivalent. Elements in the shape of points, segments or strips are cut out of this composite film or sheet by known techniques such as stamping, punching, or laser cutting.
Abstract:
An integrated window structure having opposing substrates that sandwich an electrochromic coating, a dye layer and an ion-isolating mechanism. In some embodiments, this is a selective ion-conductive layer and other embodiments incorporate nanostructures and polymers to tether the dye ions; these methods prevent dye ions from transporting into the electrochromic layer during redox activity. Control and systems to integrate the electrochromic elements in windows is provided.
Abstract:
An electrical control system for controlling a variable transmittance window is disclosed. The system comprises a driver circuit in communication with an electro-optic element. A controller is in communication with the driver circuit. The controller is configured to identify a temperature condition of the electro-optic element and adjust an output voltage supplied to the electro-optic element in response to the temperature condition.

Abstract:
In one aspect, single-junction organic photovoltaic devices are provided exhibiting high V oc values while employing single-junction architecture. A single-junction photovoltaic device described herein comprises an anode, a cathode and an active layer residing between the anode and cathode, the active layer comprising an organic electron donor and an organic electron acceptor, wherein the photovoltaic device generates a V oc of at least 1.4 V. Uniquely, high V oc photovoltaic devices described herein can be transparent to the majority of visible and/or infrared spectral irradiation in some embodiments.
Abstract:
Embodiments are disclosed of an eye-mountable device (300) including a lens enclosure including an anterior layer (305) and a posterior layer (310) sealed to the anterior layer. An anterior electrode (315) is disposed within the lens enclosure on a concave side of the anterior layer, a posterior electrode (320) is disposed within the lens enclosure on a convex side of the posterior layer, and an element (325) changing colour or opacity on demand is disposed across a central region of the lens enclosure, wherein the element separates the anterior electrode (315) from the posterior electrode (320) within the central region and can comprise liquid crystal material with a guest dye or electro-chromic material.
Abstract:
An aspect of the present disclosure is a device that includes a switchable material and an intercalating species, such that when a first condition is met, at least a portion of the intercalating species is associated with the switchable material and the switchable material is substantially transparent and substantially colorless, and when a second condition is met, at least a fraction of the portion of the intercalating species is transferred from the switchable material and the switchable material is substantially transparent and substantially colored.
Abstract:
A frequency controlled electro-optical device includes a substrate having transparent conductive control sections patterned thereon to selectively control the optical state of an electro-optical layer. Each of the control sections are partially electrically isolated from each other by crack lines, which allows for electrical communication between adjacent/proximate control sections to occur. As such, an electrical control signal applied directly to one control section forms an electric field in that control section, and also induces an electrical field in adjacent control sections that are not in direct receipt of the control signal. Therefore, the number of electrical connections required for coupling to a driving circuit to operate the device is minimized, thereby allowing the device to be fabricated with reduced complexity and cost.
