Abstract: 
We report on absorption and luminescence experiments under applied magnetic fields on Cu-and In-rich polycrystalline CuIn(Ga)Se-2 thin films. Making use of the selection rules of the absorbed polarized light we are able to identify the free exciton transition. We study its behavior as a function of the Cu/(In+Ga)-ratio (stoichiometry) and as a function of temperature to obtain the room temperature excitonic band gap. The two prominent donor acceptor pair transitions in Cu-rich films can clearly be distinguished by monitoring the degree of polarized emission in a magnetic field.
