Method and apparatus for providing a window with an at least partially transparent one side emitting OLED lighting and an IR sensitive photovoltaic panel

摘要

Embodiments of the subject invention relate to a method and apparatus for providing a apparatus that can function as a photovoltaic cell, for example during the day, and can provide solid state lighting, for example at night. The apparatus can therefore function as a lighting window. An embodiment can integrate an at least partially transparent one-side emitting OLED and a photovoltaic cell. The photovoltaic cell can be sensitive to infrared light, for example light having a wavelength greater than 1 μm. The apparatus can be arranged such that the one direction in which the OLED emits is toward the inside of a building or other structure and not out into the environment.

主权项

1. An apparatus, comprising:
an organic light-emitting device (OLED); and a photovoltaic (PV) cell, wherein the PV cell is sensitive to photons having one or more wavelengths, wherein the one or more wavelengths are in a PV cell wavelength range, and wherein at least one of the one or more wavelengths is greater than 0.70 μm, wherein the OLED comprises:
an organic light emitting layer;a mirror;an OLED anode electrode, wherein the OLED anode electrode is transparent to visible light; andan OLED cathode electrode, wherein the OLED cathode electrode is transparent to visible light,wherein the organic light emitting layer is positioned between the OLED anode electrode and the OLED cathode electrode, and wherein the mirror is positioned such that one of the OLED anode electrode and the OLED cathode electrode is between the mirror and the organic light emitting layer, andwherein at least a portion of the mirror is reflective of a first visible light wavelength range, wherein at least a first portion of visible light emitted by the organic light emitting layer has a wavelength within the first visible light wavelength range, and wherein said portion of the mirror is transmissive to a second visible light wavelength range, wherein the organic light emitting layer does not emit light having wavelengths in at least a portion of the second visible light wavelength range.
