In previous luminescence studies on CdTe epitaxial films, a line Dμ at 1.593 eV has been associated with the recombination of exciton bound to a neutral donor. We have new evidence to suggest that Dμ cannot be associated with a simple donor impurity, but should be associated with donor-like structural defects or impurity-defect complexes.

    The relaxation of excitons has been investigated in high purity AlxGa1-xAs (x up to 5%) films. After a pulsed excitation at low lattice temperatures (5 K), the time for the excitonic photoluminescence to reach its maximum shows a non-monotonic dependence on excitation density. The competition...

    We investigate point defects in CdS buffer layers that may arise from intermixing with Cu(In,Ga)Se2 (CIGSe) or Cu2ZnSn(S,Se)4 (CZTSSe) absorber layers in thin-film photovoltaics (PV). Using hybrid functional calculations, we characterize the migration barriers of Cu, In, Ga, Se, Sn, Zn, Na, and...
