Check out this nice transparent white-OLED window, from the Light & Building show 2010:

Fluxim has released a new version (v3.1) of their device simulation software SETFOS. The new version comes with a new steady-state numerical algorithm that allows for fast calculation of current-voltage curves and an improved transient solver. Fitting of experimental data for the extraction of electrical material parameters like charge mobilities and HOMO/LUMO levels becomes feasible.

The powerful optical solver is used to quantify device characteristics like radiation modes of OLEDs, absorption efficiencies of solar cells or to determine material refractive index dispersions. The software provides quantitative units for light radiation, a treatment of rough interfaces and enhanced emission zone extraction methods.
