OLED LIGHTING COMBINED WITH OPV FOR WEARABLE AND SMART WINDOW APPLICATIONS

摘要

A lighting assembly that does not require an external power source is disclosed. The lighting assembly includes a substrate, an organic light-emitting device (OLED) having a bottom electrode disposed on the substrate, an organic light-emitting layer disposed on the bottom electrode and a top electrode on the organic light-emitting layer. The lighting assembly further includes an insulating layer disposed on the top electrode of the OLED and an organic photovoltaic (OPV) device disposed on the insulating layer. The OPV device includes a series of cells, each cell has a bottom electrode, an organic photovoltaic layer disposed on the bottom electrode, and a top electrode disposed on the organic photovoltaic layer, wherein each cell is connected to at least one adjacent cell. The OPV is electrically connected to the OLED and the OPV device is configured to produce electricity to directly power the OLED.
