    • A radiation concentrator suitable for use in concentrating solar radiation for efficient and low cost solar photovoltaic use, especially for example in window-mounted devices, has a radiation-transmissive element for receiving incident radiation and includes a radiation-absorbing material for absorbing incident radiation and emitting emissive radiation, a radiation output for transmitting concentrated emissive radiation, the transmissive element acting as a wave-guide for guiding the emissive radiation to the radiation output. The concentrator is characterized by the radiation-absorbing material comprising one or more photoluminescent dyes capable of phosphorescence which exhibit a high quantum yield of phosphorescent emission that is spectrally shifted from the material's absorption.
    • 适合用于集中太阳辐射以用于高效和低成本的太阳能光伏使用的辐射集中器,特别是例如在窗户安装的装置中,具有用于接收入射辐射的辐射透射元件,并且包括用于吸收入射辐射的辐射吸收材料, 发射发射辐射,用于发射集中发射辐射的辐射输出,作为用于将发射辐射引导到辐射输出的波导的透射元件。 该集中器的特征在于辐射吸收材料包含一种或多种能够磷光的光致发光染料,其表现出从材料的吸收光谱上偏移的磷光发射的高量子产率。
