Energy harvesting windows just became affordable, as a printable coating that can be integrated directly into a dual-pane window, eliminating the need for encapsulation. The stable coating has a life expectancy of over 30 years and the window pays for itself in as little as one year.

Next Energy Technologies is producing energy harvesting windows with a new printable coating. The product exhibits the functionality of a high-performance low-e window with excellent clarity and is available in several attractive colors.

The windows offer excellent transparency while capitalizing on power conversion efficiency. They can be customized with a range of visible light transmissions from 10% to 50% and an accompanying power conversion efficiency as great as 10%. Power conversion efficiency and transparency are maintained even when subjected to high-angle and low-light conditions.

A low-cost scalable printed method further reduces overhead and the windows provide for onsite renewable energy production at half the cost of traditional solar panels. The innovative technology transforms windows into an energy harvesting asset and the windows are unparalleled in aesthetics, performance and cost. It enables architects the freedom to design a zero-energy building without breaking the bank.
