TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Component: The first film has been applied to the substrate. The second film comprises relatively greater than or equal to 25% less electron donor than the first film. The electron donor is formed through oxygen deficiencies and/or from the dopants fluorine, antimony, chlorine, gallium, tin, zinc, boron, niobium, and/or aluminum. The electron donor is present in the second film in an amount of at most 13 atomic %. The transparent conducting oxide is from tin oxide, zinc oxide, and/or indium tin oxide. The first and second films comprise tin oxide. The first mixture is applied to the substrate. The first film is formed and second mixture is applied to the topside of the first film and the second film is formed. Preferred Property: The average particle size of the crystals of the transparent conducting oxide is 50-500 nanometers (nm) in the second film. The second film has a total thickness of 300-900 nm. The first film has a total thickness of 50-500 nm.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Component: The first film has been applied to the substrate.
