“…The spectral distance between the DAP and the DAP 1LO bands as well as between the DAP 1LO and DAP 2LO bands is about ~ 28 meV, which is close to the LO phonon energy in the chalcopyrite CuInSe 2 [15]. Therefore DAP 1LO and DAP 2LO can be assigned to phonon-assisted DAP recombination with a LO phonon energy of E LO = 28 meV.…”

“…10 Note that the full width at half maximum ͑FWHM͒ of the A 1 mode is more than five times larger than that of a CuInSe 2 single crystal, thus indicating the poor crystalline quality of the layer. In addition, the presence of a lowfrequency shoulder in the 154 cm −1 region is related to the existence of complex point defects in the chalcopyrite structure ͑such as 2V Cu + V Se ͒, which give rise to the formation of ordered vacancies compounds ͑OVCs͒.…”

“…[17][18][19] The lower energy region reveals broader bands N( $1.002 eV), P ($0.972 eV), and K ($0.972 eV) along with some phonon replicas with E LO % 29 meV. 22 The shape of the K band is modified by water absorption in the region of 0.9 eV. The possible origin of these emission bands has been proposed in Ref.…”

“…High concentrations of Cu In (3 Â 10 20 cm À3 ) and no V Cu were found in CuInSe 2 with [Cu]/[In] ¼ 1.05 using neutron scattering. 49 According to ab initio calculations 22 at small excesses of copper, we can expect the following order of the formation energies for defects in CuInSe 2 (without defects related to selenium, which were not considered in this study): Cu In < V Cu < V In < Cu i < In Cu . Excluding the vacancies, whose formation has been ruled out in Refs.…”
