Mapping Current Collection in Cross Section: The case of Copper- doped CdTe Solar Cells

Multi-modal characterization of kesterite thin-film solar cells: experimental results and numerical interpretation

“…Therefore, XBIC experiments on a semiconductor device combined with modeling has been performed for a single nanowire with a 1D numerical simulation carried out using Comsol Multiphysics soware, 23 and for a single-junction, CdTe/CdS solar cell with 2D dri-diffusion modeling. 24,25 In this paper, we present the results of the multi-modal study of a CZTS solar cell cross-section by employing combined measurements of scanning X-ray analytical techniques for a correlative investigation of the structural, chemical and electrical properties of a fully functional device at the nanoscale. We support experimental data with the nite volume modeling of the XBIC signal by solving Poisson's equation and the continuity equations for electrons and holes within the 2D computational domain constructed from the XRF data.…”
