Engineering Smart Windows Using Arduino

The Window, a common household feature has great potential to become an automated system implemented in homes across the globe. In this project we designed and constructed a prototype of a marketable Smart Window utilizing the Arduino microcontroller. This open-source platform allowed us to use a variety of sensors to evaluate internal and external conditions and adjust the settings of a room a...

Smart Windows: Ultrathin Fluidic Laminates for Large‐Area Façade Integration and Smart Windows (Adv. Sci. 3/2017)

Low-voltage electrochromic device for photovoltaic-powered smart windows

We report the properties of an all-solid-state electrochromic ~EC! device that can be switched over a useful range of optical transmissions with voltages below 1 V. This switching voltage is smaller than required by other solid-state EC devices reported to date. We attribute the lower-than-normal switching voltage to the use of a thermally evaporated MgF2 thin film as the lithium ion conducting...

BIPV-Powered Smart Windows Utilizing Photovoltaic and Electrochromic Devices

A BIPV-powered smart window comprising a building-integrated photovoltaic (BIPV) panel and an all-solid-state electrochromic (EC) stack is proposed. In the proposed device, the output voltage of the BIPV panel varies in accordance with the intensity of the incident light and is modulated in such a way as to generate the EC stack voltage required to maintain the indoor illuminance within a speci...

Integrated smart electrochromic windows for energy saving and storage applications.

A self-powered electrochromic smart window with tunable transmittance driven by dye-sensitized solar cells has been designed, which also acts as a photocharged electrochromic supercapacitor with high areal capacitance and reversible color changes.
