Advanced Technologies for Smart Windows.

Project goals

(1) 50% weight reduction by using ultra thin glass membranes

(2) 50% heat loss reduction by introduction of quadruple IG-unit (envisaged Ug-value: 0.3 W/m²K)

(3) 20% cost reduction (compared to a conventional window with the same functionalities) by advanced fabrication technologies and replacement of cost intensive materials

(4) modular solutions for energy harvesting with smart window: (a) in-line printed Organic Photovoltaic (OPV) for power generation; (b) fully integrated solar-thermal collector for warm water supply

(5) modular solution for control of solar radiation and light guidance with switchable micro-mirrors (envisaged range of transmission between 75% and 2%)

At the end of the project the aforementioned modular compo-nents like micro mirror arrays, OPV, solar thermal collector as well as organic light emitting diodes (OLEDs) will be integrated into a fully functional demonstrator showing the suitability of the used equipment, processes and new materials developed.
