Abstract: Multilayered polymer films are configured so that successive constituent layer packets can be delaminated in continuous sheet form from the remaining film. The films are compatible with known coextrusion manufacturing techniques, and can be made without adhesive layers between layer packets that are tailored to be individually peelable from the film. Instead, combinations of polymer compositions are used to allow non-adhesive polymer layers to be combined such that irreversible delamination of the film is likely to occur at interfaces between layer packet pairs. Some polymer layers, including at least one embedded layer, may include an ultraviolet (UV) light stabilizer such as a UV absorber, antioxidant, or hindered amine light stabilizer (HALS), and these layers may be positioned at the front of each layer packet. After the UV-stabilized layer of one packet has been used, the packet can be peeled away to expose a new UV-stabilized layer of the next layer packet.

Some of the polymer layers, including at least one embedded layer, comprise an antimicrobial agent, and these layers may be positioned at the front of each layer packet. After the antimicrobial layer of one layer packet has been used, the packet can be peeled away to expose a pristine antimicrobial layer of the next layer packet. The antimicrobial agent may be organic.

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.

Abstract: Multilayered polymer films are configured so that successive constituent layer packets can be delaminated in continuous sheet form from the remaining film. The new films are compatible with known coextrusion manufacturing techniques, and can also be made without the use of adhesive layers between layer packets that are tailored to be individually peelable from the remainder of the film. Instead, combinations of polymer compositions are used to allow non-adhesive polymer layers to be combined in such a way that delamination of the film is likely to occur along a plurality of delamination surfaces corresponding to interfaces between particular pairs of layers for which the peel strength is reduced relative to the peel strength at other layer interfaces within the film. The absence of an adhesive between peelable layer packets results in the delamination being irreversible.
