Fully solution processed monochromatic and white‐light emitting tandem or multi‐photon polymer OLEDs with an inverted device architecture have been realized by employing WO 3 /PEDOT:PSS/ZnO/PEI charge carrier generation layers. The luminance of the sub‐OLEDs adds up in the stacked device indicating multi‐photon emission. The white OLEDs exhibit a CRI of 75.
