    • The invention relates to solar thermal receiver for a solar thermal energy plant comprising a light absorber (11) comprising nanoparticles (13) in a host material (15) which is transparent in an absorbing range of the light absorber (11) and where the nanoparticles (13) exhibit plasmonic resonances within the absorbing range of the light absorber (11), wherein the dispersion of the nanoparticles (13) in the host material is controlled in such a way that the mean distance between said nanoparticles (13) is lower than the wavelengths of light in the absorbing range of the light absorber (11) for generating near field radiation interactions between said nanoparticles (13). The size and the distribution of the nanoparticles (13) is chosen to obtain a cutoff wavelength, where light of higher wavelength than the cutoff wavelength is less absorbed than light at shorter wavelengths with respect to the cutoff wavelength reducing losses due to infrared radiation of the absorber
    • 本发明涉及一种用于太阳能热能设备的太阳能热接收器,其包括在主体材料(15)中包含纳米颗粒(13)的光吸收体(11),其在光吸收体(11)的吸收范围内是透明的,其中纳米颗粒 (13)在光吸收体(11)的吸收范围内具有等离子体共振,其中,将主体材料中的纳米粒子(13)的分散体以这样的方式进行控制,使得所述纳米粒子(13)之间的平均距离低于 用于产生所述纳米颗粒(13)之间的近场辐射相互作用的光吸收体(11)的吸收范围内的光的波长。 选择纳米颗粒(13)的尺寸和分布以获得截止波长,其中比截止波长高的波长的光比相对于截止波长的光更少地吸收,由于红外辐射导致的截止波长减小 吸收
