A smart glazing technology addressing color, tint uniformity and cost challenges

Electrochromic dynamic smart windows offer many benefits of energy savings and comforts, including daylighting, glare control, unobstructed views. Smart windows target markets are commercial buildings, residential homes, skylight, automotive and transportation (planes, buses, ships). Current commercially available products have struggled to reach large market adoption due to their (1) high installed cost, (2) transmitted and reflected colors, (3) optical uniformity and (4) difficulty coating on curved glass (example automotive sunroof). Heliotrope’s product development strategy is to resolve these issues using a colloidal nanocrystal (CNC) platform technology. Through the CNC platform, Heliotrope is able to offer material systems that provide variable spectral control (visible, NIR, and MIR), customizable tint color (neutral, blue, etc.), wide dynamic range of light transmission and enable coating on curved glass. Unlike traditional PVD electrochromic products, CNC products are fabricated using low cost, high throughput solution process techniques with lower manufacturing cost. We will discuss the unique attributes of Heliotrope’s technology that will overcome the current market barriers for mass adoption of dynamic glazing.
