Color Glass by Layered Nitride Films for Building Integrated Photovoltaic (BIPV) System

We investigated layered titanium nitride (TiN) and aluminum (AlN) for color glasses in building integrated photovoltaic (BIPV) systems. AlN TiN are among suitable cost-effective optical materials to be used as thin multilayer films, owing the significant difference their refractive index. To fabricate structure, we radio frequency magnetron deposition method achieve target thickness uniformly. A simple, fast, cheap fabrication is achieved by depositing films a single sputtering chamber. It demonstrated that stack allows light transmitted from low index layer high or vice-versa can effectively create various distinct reflections different film thicknesses structures. simulation based on wave optics TiN/AlN offers better design freedom cheaper process compared AlN/TiN films. Blue, green, yellow with transmittance of more than 80% was indium tin oxide (ITO)-coated glass/TiN/AlN This technology exhibits good potential commercial BIPV system applications.
