“…One approach to spectral control is to use selective emitters, such as rare earth materials discussed earlier, which have a high emissivity in favorable wavelength bands. Another approach is to use filters that reflect longer wavelengths away, while shorter desirable wavelengths pass through to the photocells [14][15][16][17]. Spectral control keeps the cells cooler, reduces waste heat management, and increases fuel-to-electric conversion efficiency.…”

“…• Filtros ópticos interferenciales de capas dieléctricas. La opción quizá más extendida, por su sencillez y fiabilidad, es la del depósito de una capa múltiple de dieléctricos que alterne sus índices de refracción [Good96] [Horne96] sobre sustratos transparentes resistentes a las altas temperaturas, como cuarzo o Pirex. En [Coutts99] se demuestra que considerando un número suficiente de capas dieléctricas se consiguen filtros ópticos con respuestas muy cercanas a la ideal.…”

“…Mediante capas delgadas de TCOs se pueden conseguir filtros de plasma que presentan muy buenas características espectrales [Coutts99]. Cuando se usan en combinación con filtros interferenciales, se pueden obtener valores de reflectividad del 90% para longitudes de onda elevadas y transmitividades del 75% [Baldasaro94] [Good96]. Recientemente se ha considerado la integración del filtro de plasma de TCOs en la propia estructura de la célula termofotovoltaica, sustituyendo a la vez a la malla de metalización y la capa antirreflectante [Ruiz04] y eliminando las pérdidas por sombreado.…”
