Abstract:
Visually undistorted thin film electronic devices are provided. In one embodiment, a method for producing a thin-film electronic device comprises: opening a scribe in a stack of thin film material layers deposited on a substrate to define an active region and an inactive region of the thin-film electronic device, the stack comprising at least one active semiconductor layer. The active region comprises a non-scribed area of the stack and the inactive region comprises a region of the stack where thin film material was removed by the scribe. The method further comprises depositing at least one scribe fill material into a gap opened by the scribe. The scribe fill material has embedded therein one or more coloring elements that alter an optical characteristics spectrum of the inactive region to obtain an optical characteristics spectrum of the active region within a minimum perceptible difference for an industry defined standard observer.

Abstract:
Systems and methods for transparent organic photovoltaic devices are provided. In one embodiment, an organic semiconductor device comprises: a first glass sheet (105) comprising a first ultra-thin flexible glass material; at least one transparent organic photovoltaic cell (120) bound to the first glass sheet; and a second glass sheet (110) applied to the at least one organic photovoltaic cell (120), wherein the at least one transparent organic photovoltaic cell (120) is positioned between the first glass sheet (105) and the second glass sheet (110).
