Solar Cell Module with 3D Floating Image

    It is sometimes desired to alter the appearance of a photovoltaic device or solar cell. Figure 1 shows a thin film solar cell positioned above a 3D floating image film which is positioned over a backlight. The solar cell is translucent or semi-transparent. Such solar cells can be made by perforating (via laser ablation, for example) a thin film solar cell. The perforations may be random or may be on lattice or may be patterned. The thin film solar cell is positioned between a glass layer and an encapsulant. An ultra-barrier film (UBF) or glass layer may be positioned adjacent the encapsulant. Suitable 3D floating image films include those described in U.S. Patent Application 2013/0065203 and in U.S. Patent 8,459,807, U.S. Patent 7,336,422 and U.S. Patent 6,288,842. A portion of the power generated by the solar cell may be used to power the backlight so that the assembly is self-powered. Such an assembly may have application as a self-powered billboard or may be used in other types of advertisement or as decoration.
