Abstract:
A photo-active device is provided that has a cavity in an integrated, transparent mold material. An active material layer is disposed therein along with other layers disposed in and about said cavity to define a dome-like array architecture. A process for forming the dome-like array structure includes disposing an active layer into a series of empty periodically positioned cavities of a dome-like array template working mold material. Each of the series of empty periodically positioned cavities has curvature variations of the interior surface of the dome-array cavities optimized for device efficiency, reduction of performance sensitivity to light impingement angle, or a combination thereof. At least one of absorber layers, contact layers, spacer/transport layers, and electrode layers are also disposed in the series of cavities.
