Near-infrared optical upconverter based on i-In0.53Ga0.47As/C60 photovoltaic heterojunction
A near-infrared to visible light optical upconverter by the integration of an i-In0.53Ga0.47As/C60 junction and an organic light emitting diode is reported. This device shows the photovoltaic effect of an i-In0.53Ga0.47As/C60 heterojunction and potential application in a pixelless upconversion imaging device.
