Abstract: An example article may include an optical filter and a multilayer stack adjacent the optical filter. The multilayer stack may include a plurality of layers. Each respective layer of the plurality layers may define a respective window edge of a plurality of window edges. The plurality of window edges may define an optical window configured to transmit light through the optical filter. At least a first respective window edge of the plurality of window edges may be stepped relative to at least a second respective window edge of the plurality of window edges.

Abstract: Multi-layered solar cell devices covered with partially transmissive graphic films. The multi-layered solar cell devices include at least one solar cell, a graphics layer over the solar cell, and a reflective layer. The reflective layer can be behind the solar cell for recycling light or between the partially transmissive graphic film and the solar cell for improved appearance. The multi-layered solar cell devices have a high efficiency and a customizable appearance.
