Espectroscopia de impedancias aplicada a dispositivos semiconductores

Abstract

Este proyecto consiste en el análisis y diseño de células solares de altas prestaciones de diferentes estructuras y características físicas, y otros dispositivos como un microcondensador de gran capacidad (supercondensador), mediante espectroscopia de impedancias. Primero se han realizado mediciones mediante espectroscopia de impedancias que permite inyectar una pequeña señal eléctrica en un barrido frecuencial a diferentes polarizaciones y medir la respuesta del dispositivo. Esto permite obtener los diagramas de Bode y de Nyquist de la impedancia. Utilizando un modelo circuital se han ajustado los resultados, obteniendo los parámetros y factores de mérito que caracterizan a dichos dispositivos. Finalmente, del análisis de estos valores se pueden encontrar condiciones de diseño que permiten indicar como mejorar su funcionamiento.

Finalment, de l’anàlisi dels valors obtinguts es poden trobar condicions de disseny que permeten indicar com millorar el seu funcionament.

This project is based on the analysis and design of high performance solar cells of different structures and physical characteristics, and other devices such as big capacity capacitor (supercapacitor), using the Impedance Spectroscopy. Firstly, it has been done measurements using Impedance spectroscopy that allows to inject to the device a little power electrical signal in a frequency sweep at different voltage offsets and measure the response of the device. This allows to obtain Bode and Nyquist diagrams of the impedance. Using a circuit model the results has been adjusted, obtaining the parameters and merit factors that characterize the behavior of the studied devices. Finally, after the analysis of the values it is possible to obtain conditions for the design that allows to improve the performance of the devices.

Medir y modelar medidas realizadas mediante espectroscopía de impedancias a dispositivos semiconductores. A partir de los resultados obtenidos, extraer los parámetros y las figuras de mérito que modelan su comportamiento y realizar mejoras de diseño.
