Simulation of Heat Transfer in Low-Voltage Switchboard MNS
The content of this work is the diagnosis of the temperature profile of industrial low voltage switchboards. Place of origin, flow and heat dissipation are important aspects in the design of the cabinet, particularly with regard to the layout of your devices. The correctness of the design cabinet can be verified by measuring the temperature field practical cabinet during testing or in work mode. Another option is to simulate the temperature profile of the low voltage. This can prevent waste of materials and saving money for the developmen
Capacitance spectroscopy of thin film formamidinium lead iodide based perovskite solar cells
This work concerns the interpretation of capacitance spectroscopy results in perovskite based solar cells. Based on the deep level transient spectroscopy and admittance spectroscopy results, we present arguments that the observable signals in perovskite based solar cells come from anion migration rather than being a response from deep trap energy levels. The ion migration parameters, such as activation energy and ion concentration, are calculated and compared to theoretical values for different migration paths of ions in perovskites. Those parameters evolve with time, reflecting in the degradation of the cells, which we propose to link with a change in the anion migration path in perovskit
