Abstract:

At this work the principle aim is to create new low cost hardware test circuitry that can emulate the behavior of solar cells under different insolation and temperature conditions. Another goal is to propose a new MPPT algorithm that could accurate and reliable estimate the maximum power operating point. The transcendental equation describing a solar cell IV characteristic contains current on both sides in a function of the form I = f (V, I). In this work, a current-independent voltage expression is derived for the maximum power point as a function of a new variable which is mathematically wel

Abstract:

The need to increase the share of electricity produced from renewable resources has pushed the installation of photovoltaic systems. Solar sources in recent years have experienced strong growth both in terms of investments and installations. In fact, in 2018, solar energy had a global generation capacity of 43% compared to all other power generation technologies. In the coming years, the use of solar energy will grow rapidly, especially for use in different applications. Therefore, studying the behavior of photovoltaic panels and having a model that accurately describes their behavior is essen

Abstract:

Dispositifs photovoltaïques d'aujourd'hui convertissent l'énergie solaire en électricité de manière propre, renouvelable et inépuisable et représentent un remplacement possible pour les combustibles fossiles. Toutefois, afin de rivaliser avec les sources d'énergie classiques une augmentation significative de l'efficacité de conversion est inévitable. Dans ce travail, nous nous concentrons sur des aspects pouvant propulser le rendement de conversion au-dessus des limites de cellules présentes. La première partie de l'étude est consacrée à de nouvelles idées théoriques considérés comme le photov

Abstract:

[ES] Desde hace una década se esta investigando intensamente la forma de mejorar la eficiencia de conversión de energía (PCE) de las células solares de silicio (Si) y reducir sus precios. Sin embargo, a pesar de las mejoras obtenidas, la fabricación de células solares de Si sigue siendo costosa y puede rebajarse usando materiales en forma de capa fina. Por ello la búsqueda de materiales absorbentes alternativos, no tóxicos, abundantes en la naturaleza y con buenos rendimientos de conversión se ha intensificado en los últimos años. Entre los diferentes materiales absorbentes el sulfuro de esta

Abstract:

This thesis studied cadmium sulfide and cadmium selenide quantum dots and their performance as light absorbers in quantum dot-sensitised solar cells. This research has made contributions to the understanding of size dependent photodegradation, passivation and particle growth mechanism of cadmium sulfide quantum dots using SILAR method and the role of ZnSe shell coatings on solar cell performance improvement.

碩士<br>國立臺灣大學<br>電機工程學研究所<br>97<br>In the present document, three different initiatives taken on behalf of efficiency improvement of wafer based solar cells are presented. First, MIS Solar cells are theoretically analyzed and the outcome is verified by means of TCAD simulation software. Al/SiO2/ptype Si and ITO/SiO2/nType Si devices are constructed and tested obtaining negative results that discard the utilization of transparent conductive oxides as promising contact materials for MIS solar cells. The influence of front surface recombination on solar cell behavior is examined and an improvement

Abstract:

碩士<br>元智大學<br>電機工程學系<br>94<br>The purpose of this thesis is to develop a high-efficiency power conditioner for a solar photovoltaic (PV) system. In order to make the solar PV system more flexibility and expandability, the later power circuit is composed of a high step-up dc-dc converter and a full-bridge inverter. A conventional boost converter with a single inductor is the common usual. However, the main switch in this circuit must possess the power capability of high voltage and large current, and it has the problem of reverse-recovery within the output diode. As a result, the conversion eff
