Abstract: Near-ultraviolet (NUV) absorbing compounds are described herein which, in some embodiments, provide enhanced optoelectronic properties and visible light transmittances when employed as organic electron donors in various photovoltaic architectures. Photovoltaic devices incorporating such NUV-absorbing compounds in the active layer are also described.

Abstract: A decorative tree ornament that is positioned atop a tree and that lights up and plays music while presenting an ornamental display that is attached to a rotating platform. The rotating is driven by a motor and support by a sheath that is designed to be fitted about the top of the tree. A plurality of slits traverses through the sheath, allowing the sheath to be navigated around the branches of the tree. A microcontroller dictates the speed of the motor, audio files played from a speaker, and the brightness and color of light emitted from a light assembly of the ornamental display. The light assembly is integrated into a festive diorama that is encased in a dome enclosure; the festive diorama and the dome enclosure both being removably attached to the rotating platform. A stabilization post is further utilized to support the sheath and the rotating platform.
