In this work we present a versatile simulation tool for the batch processing of solar cell simulation by using Matlab and the wxAMPS console version. The wxAMPS console version gives a programming interface for other software to call the simulation kernel of wxAMPS, and Matlab provides a favorable platform to define the modeling process and design the data visualization. This method offers users a...
Chalchopyrite CIGS thin films were prepared by the two-stage growth technique. The processes were based on the controlled selenization of sputtering metallic precursors with elemental Se vapor in closed space. The modified selenization process by fitting data prevented the substantial losses and the formation of voids from the interior of absorbers. Accordingly, adhesion was improved and the grain...
Passivation of Ge has been a critical issue for Ge MOS applications in future technology nodes. In this letter, we introduce ozone oxidation to engineer Ge/insulator interface. Density of interface states (Dit) across the bandgap and close to the conduction band edge was extracted using conductance technique at low temperatures. Dit dependence on growth conditions was studied. Minimum Dit of 3 times...
