A monolithic thin-film electrochromic window

Daylighting control performance of a thin-film ceramic electrochromic window: field study results

Control system development and lighting energy monitoring of ceramic thin-film electrochromic (EC) windows were initiated at the new full-scale Window Systems testbed facility at the Lawrence Berkeley National Laboratory (LBNL) in Berkeley, California. The new facility consists of three identically configured side-by-side private offices with large-area windows that face due south. In one room,...

Development of Flexible Electrochromic Device with Thin Film Configuration

Improving Electrochromic Properties of WO3 Thin Film with Gold Nanoparticle Additive

In this research, WO3 and Au-WO3 thin films were prepared at different temperatures using the sol gel method. The effect of gold nanoparticles (GNPs) on the electrochromic properties of WO3 was also studied. 2.5 nm GNP was synthesized through sodium citrate reduction of gold chloride in an aqueous solution. These films were characterized by XRD, SEM, TEM, and spectrophotometer analyses. The fil...

Monolithic integration of thin-film coolers with optoelectronic devices

Patrick Abraham John E. Bowers Department of Electrical and Computer Engineering University of California–Santa Barbara Santa Barbara, California 93106-9560 Abstract. Active refrigeration of optoelectronic components through the use of monolithically grown thin-film solid-state coolers based on III-V materials is proposed and investigated. Enhanced cooling power compared to the thermoelectric e...

Thin-Film Quantum Dot Photodiode for Monolithic Infrared Image Sensors †

Imaging in the infrared wavelength range has been fundamental in scientific, military and surveillance applications. Currently, it is a crucial enabler of new industries such as autonomous mobility (for obstacle detection), augmented reality (for eye tracking) and biometrics. Ubiquitous deployment of infrared cameras (on a scale similar to visible cameras) is however prevented by high manufactu...
