Photonics in photovoltaic systems
No full textThis paper gives an overview on photonics for photovoltaic systems. Starting from the spectral and angular distribution of the electromagnetic radiation from the sun, many important optical approaches how to improve the efficiency of solar cells are presented and discussed. Topics include antireflective coatings, various light trapping structures, refractive, reflective and fluorescent concentrators, and components for spectral management. The theoretical background is shortly described and examples of the experimental and also of the commercial realisation are given
Application of photoluminescence and electroluminescence techniques to the characterization of intermediate band solar cells
No full textThe intermediatebandsolarcell (IBSC) is a photovoltaic device with a theoretical conversion efficiency limit of 63.2%. In recent years many attempts have been made to fabricate an intermediateband material which behaves as the theory states. One characteristic feature of an IBSC is its luminescence spectrum. In this work the temperature dependence of the photoluminescence (PL) and electroluminescence (EL) spectra of InAs/GaAs QD-IBSCs together with their reference cell have been studied. It is shown that EL measurements provide more reliable information about the behaviour of the IB material inside the IBSC structure than PL measurements. At low temperatures, the EL spectra are consistent with the quasi-Fermi level splits described by the IBSC model, whereas at room temperature they are not. This result is in agreement with previously reported analysis of the quantum efficiency of the solarcell

Realidad, mito y deseo. La mirada grecolatina de Aurora Luque
No full textAurora Luque’s poetry is one of the most representative of contemporary poetry, located within a Greek culturalism, where myth and reality blend into everyday life. Luque’s poetry is characterized by irony, nonchalance, frivolity and dedramatization. The article presents a series of poems where one can find a demystification of the classical element. A poetry stressed by some topoi such as carpe diem or Catullus’ odio et amo, which have been always represented from a light-hearted glance ruled by the spirit of Eros. The article also emphasizes the play on intertextuality –following Catullus– as well as the epicurean inclination/spirit/passion of the autor.La poesía de Aurora Luque representa una de las poéticas más representativas de nuestra contemporaneidad, ubicada dentro de un culturalismo grecista, donde mito y realidad se conjugan dentro de la cotidianidad.
