Stainless steel foil substrate

It is known that most metals possess lower gas permeability than plastics by 6-8 orders of magnitude. An unbreakable and lightweight thin stainless steel foil substrate has been used for flexible OLEDs [75]. Therefore, a several micrometers thick metal layer can serve as a highly effective barrier to minimize the permeation of oxygen and moisture. Hence, the...

A schematic cross-section of a p-i-n a-Si H solar cell [11] is shown in Figure 72a. In this so-called superstrate configuration (the light is incident from above), the material onto which the solar cell structure is deposited, usually glass, also serves as a window to the cell. In a substrate configuration the carrier onto which the solar cell structure is deposited forms the back side of the solar cell. The carrier usually is stainless steel, but flexible materials such as metal-coated polymer foil (e.g. polyimid) ora very thin metal make the whole structure flexible [11]. 

HDPE, composite materials such as epoxy-glass fiber and epoxy-carbon fiber, and laminate structures such as polymer films on bulk metal substrates. Thin-conductive film heaters were made of electrically conductive paints, electrically conductive polymer films, metal foils (stainless-steel, copper, titanium, and titanium alloys), and thin metal films sputtered on a ceramics or glass. The samples dimensions varied from a few centimeters to 5m.
