We have simulated unique textured window films that capture solar radiation without compromising the window's transparency by scattering infrared light toward photovoltaic strips located at the edges of the window. These films are ideal for powering electrochromic glass, which is difficult to install as each window requires its own power source. Our most promising design consists of an embedded array of 35° cones coated with a five-layer SiO2-Ag stack that was simulated to direct 1.4% of the incident light toward the edges and generate 1 W of power under a collimated 1000 W/m2 AM1.5G source at 60° and an average of 0.5 W over a full year when applied to a 1 m×1 m window. The internal visible transmittance of the window with the applied film is 95% at normal incidence, and remains above 85% for viewing angles up to 60°. The haze is 0.6% at normal incidence and 3.9% at 60°.
The Pylux family of polysulfide thermosetting polymers (PSTs) has been developed to enhance manufacturing options for a wide range of flexible displays and electronics.
The TFT‐alley process for high resolution and large screen size TFT‐LCD such as 20UXGA (1600×1200) is developed without the need for extra processing steps. A demonstrated novel process uses Pure‐Al metal as gate and source electrode with low dielectric interlayer, which can result in achieving high performance a‐Si TFT with high yield. 18.1SXGA(1280×1024) panel was already introduced in the mass production and achieved high cost performance with high aperture ratio.
A new material, ATB, is demonstrated as a temporary bonding layer for a poly(amic acid)-based, solution-cast polyimide and Pylux -MF, a polysulfide thermoset. Both films are deposited atop carriers coated with ATB and after device definition, are removed from the carriers using a 90° tensile peel with peel strengths below 10 cN/cm.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
