title = "Study of wavelength-resolved light-induced metastable defects in (Ag,Cu)(In,Ga)Se2 thin-films using capacitance based methods",
abstract = "Metastable defects created in silver alloys of copper indium gallium diselenide (ACIGS) are studied using admittance spectroscopy and drive level capacitance profiling (DLCP). Admittance spectroscopy is used to extract the activation energy of the defects and DLCP is used to extract the density and spatial distribution of the defects. The study confirms that addition of silver reduced the drive level density - defined as the sum of the carrier concentration and the defect density - by over two orders of magnitude. The mechanism of formation of light-induced defects in these chalcogenides is probed further by activating the defects using spectrally-resolved light with energy both below and above the device bandgap.",
