Abstract
Laminated (and, in some cases, additionally etched) glazing units for cooperation with solar-energy systems during architectural integration thereof include an optically-transparent substrate in contact with an incident medium, on one side, and with a non-quarter-wave thin-film-stack based interference filter on another side, followed by an exit medium. Embodiments are practically applicable to conceal physical structures disposed behind them and characterized by IR-light transmittance that is enhanced (as compared with conventional glazing units based on quarter-wave thin-film-stacks and similarly utilized) to improve efficiency of a solar-energy system carrying at least a portion of such glazing unit on its front surface. Colour of reflected light perceived as a function of angle is sufficiently stabilized for practical applications. In specific cases, a solar-energy system is integrated inside or with such a glazing unit.
