One diode circuital model of light soaking phenomena in Dye-Sensitized Solar Cells
2018
Abstract In this work, we report on the modelling of light soaking effect on Ruthenium-based Dye Sensitized Solar cells (DSSCs). Such a phenomenon can be detected when exposing the cells at increasing hours of illumination and produces a reversible performance increase. Starting from the results obtained through the electro-optical characterization of the cells, we applied a one-diode circuital-model. Our results show a good agreement between the experimental and the simulated data, with a mean square error in the order of 10−12 and a maximum error in current lower than 0.6%. Finally such results allowed us to infer some precise trends followed by the cells main electrical parameters and of…
Obtaining the electrical model of a power transformer by means of finite element software
2005
Abstract. The behaviour of transformers and inductors working at high-frequencies and high power density can dramatically differ from the ideal or low-frequency operation. Their performance is very dependent on the magnetic material, operating frequency and physical construction. In this paper, finite element analysis (FEA) is used to obtain an accurate characterization of the electromagnetic behaviour of these magnetic components.
Extensive electrical model of large area silicon photomultipliers
2011
Abstract In this paper the full electrical model of silicon photomultipliers fabricated at STMicroelectronics Catania R&D clean room facilities is presented. An accurate investigation on both SiPM single microcell and entire SiPM structure to extrapolate all the electrical elements has been executed by means of dedicated characterizations carried out on appropriate layout structure. The electrical simulations results are compared to the experimental data showing a good fit and therefore verifying the accuracy of the proposed model. This model can be used to describe all the SiPMs with different sizes manufactured using the same technology. Moreover, starting from this extensive electrical m…
3D Printing Neuron Equivalent Circuits: An Undergraduate Laboratory Exercise.
2018
The electrical equivalent circuit for a neuron is composed of common electrical components in a configuration that replicates the passive electrical properties and behaviors of the neural membrane. It is a powerful tool used to derive such fundamental neurophysiological equations as the Hodgkin-Huxley equations, and it is also the basis for well-known exercises that help students to model the passive (Ohmic) properties of the neuronal membrane. Unfortunately, as these exercises require basic knowledge of electronics, they are generally not physically conducted in biomedical courses, but remain merely conceptual exercises in a book or simulations on a computer. In such manifestations, they l…
