Interpreting results of spatially resolved characterization methods can prove quite a challenge and it may often happen that a phenomenon takes credit for something it is not responsible for. This is especially important when imaging laterally inhomogeneous devices. We present a derivation, application and validation of a combined opto-electrical model, which sheds light on the roles electrical and optical effects play when it comes to interpretation of EL measurements. We show not only that the device optics and imaging optics cannot be neglected but that they in fact play a major role in shaping the EL measurements.
