    Starting on June 2011, NGCPV is the first project funded jointly between the European Commission (EC) and the New Energy and Industrial Technology Development Organization (NEDO) of Japan to research on new generation concentration photovoltaics (CPV). The Project, through a collaborative research between seven European and nine Japanese leading research centers in the field of CPV, aims at lowering the cost of the CPVproduced photovoltaic kWh down to 5 ?cents. The main objective of the project is to improve the present concentrator cell, module and system efficiency, as well as developing advanced characterization tools for CPV components and systems. As...

  2. Outline of Europe-Japan collaborative research on concentrator photovoltaics

    Luque López, Antonio; Yamaguchi, Masafumi
    The Europe-Japan Collaborative Research Project on Concentrator Photovoltaics (CPV) has been initiated under support by the EC (European Commission) and NEDO (New Energy and Industrial Technology Development Organization) since June 2011. This is project (NGCPV Project; a New Generation of Concentrator PhotoVoltaic cells, modules and systems) is aiming to accelerate the move to very high efficiency and lower cost CPV technologies and to enhance widespread deployment of CPV systems. 7 organizations such as UPM, FhG-ISE Imperial College, BSQ, CEA-INES, ENEA, and PSE in Europe and 9 organizations such as TTI, Univ. Tokyo, AIST, Sharp Co. Daido Steel Co., Kobe Univ.,...

  3. Diseño de una red de fibra óptica para la implementación de servicios de una banda ancha en una zona de viviendas en casco urbano

    Barroso García, Andrés
    El objetivo del proyecto es el diseño y la instalación de una red de fibra óptica para la implementación de servicios de banda ancha en una zona de viviendas. Mediante esta instalación se dará servicio de fibra óptica hasta el hogar (FTTH). El proyecto cubre la instalación desde la Central de Comunicación hasta los usuarios.

  4. Comments and remarks over classic linear loop-gain method for oscillator design and analysis. New proposed method based on NDF/RRT

    Jiménez Martín, José Luis; González Posadas, Vicente; Parra Cerrada, Angel; García-Muñoz, Luis Enrique; Segovia Vargas, Daniel
    Abstract. This paper describes a new and original method for designing oscillators based on the Normalized Determinant Function (NDF) and Return Relations (RRT)- Firstly, a review of the loop-gain method will be performed. The loop-gain method pros, cons and some examples for exploring wrong solutions provided by this method will be shown. This method produces in some cases wrong solutions because some necessary conditions have not been fulfilled. The required necessary conditions to assure a right solution will be described. The necessity of using the NDF or the Transpose Return Relations (RRT), which are related with the True Loop-Gain, to test the additional conditions will be demonstrated. To...

  5. NGCPV: A new generation of concentrator photovoltaic cells, modules and systems

    Cristóbal López, Ana Belén; Martí Vega, Antonio; Sala Pano, Gabriel; Bett, Andreas W.; Ekins-Daukes, Ned; Roca, Franco; Luque Heredia, Ignacio; Warmuth, Werner; Merten, Jens; Okada, Y.; Hishikawa, Y.; Takamoto, Tatsuya; Araki, Kenji; Fukuyama, A.; Kuze, N.; Kita, T.; Kotagiri, Akira; Yamaguchi, Masafumi; Luque López, Antonio
    This work introduces the lines of research that the NGCPV project is pursuing and some of the first results obtained. Sponsored by the European Commission under the 7th Framework Program and NEDO (Japan) within the first collaborative call launched by both Bodies in the field of energy, NGCPV project aims at approaching the cost of the photovoltaic kWh to competitive prices in the framework of high concentration photovoltaics (CPV) by exploring the development and assessment of concentrator photovoltaic solar cells and modules, novel materials and new solar cell structures as well as methods and procedures to standardize measurement technology for...

  6. Red adaptativa de conmutación suave para convertidor trifásico en puente activo completo para aplicaciones de vehículos eléctricos

    Molina Garcia, Jose Maria; García Suárez, Oscar; Asensi Orosa, Rafael; Oliver Ramírez, Jesús Angel; Alou Cervera, Pedro; Cobos Márquez, José Antonio
    En éste artículo se presenta el control adaptativo de un circuito auxiliar para conseguir conmutaciones suaves en todo el rango de carga en los semiconductores principales de un convertidor cargador de baterías trifásico basado en doble puente activo. Mediante este sistema se consigue tener ZVS en todo el margen de carga, sin ser necesaria la modificación de los parámetros del circuito ni de los semiconductores principales. Los principios de operación de este circuito y su control se comprobarán experimentalmente en un convertidor cargador de baterías de características similares al utilizado en el HYBRID TOYOTA PRIUS

  7. Modelling of quantum dot solar cells for concentrator PV applications

    Ogura, A.; Morioka, T.; García-Linares Fontes, Pablo; Hernández Martín, Estela; Ramiro Gonzalez, Iñigo; Artacho Huertas, Irene; Antolín Fernández, Elisa; Martí Vega, Antonio; Luque López, Antonio; Yamaguchi, Masafumi; Okada, Y.
    An equivalent circuit model is applied in order to describe the operation characteristics of quantum dot intermediate band solar cells (QD-IBSCs), which accounts for the recombination paths of the intermediate band (IB) through conduction band (CB), the valence band (VB) through IB, and the VB-CB transition. In this work, fitting of the measured dark J-V curves for QD-IBSCs (QD region being non-doped or direct Si-doped to n-type) and a reference GaAs p-i-n solar cell (no QDs) were carried out using this model in order to extract the diode parameters. The simulation was then performed using the extracted diode parameters to...

  8. Desarrollo de un drive para motores paso a paso y aplicación del filtro de Kalman para el sistema de colimación del LHC = Development of a stepper motor drive and Kalman Filter application for the LHC collimation system

    Picatoste Ruilope, Ricardo
    Este proyecto describe el trabajo realizado durante 14 meses en una estancia en prácticas para estudiantes del CERN. El trabajo consiste en el desarrollo, implementación y testeo de un drive para motores paso a paso que se utilizará en el sistema de colimación del LHC. Se propone así mismo la utilización del filtro de Kalman para obtener una estimación del ángulo, desarrollandose una implementación del mismo aplicable en tiempo real.
