    • The disclosed invention relates to solar-thermal receiver tubes for heating high-temperature fluids such as molten salts and oils, such as those used in conjunction with trough reflectors or concentric concentrators. The disclosed invention utilizes fused silica receiver tube assemblies that provide optical absorption by way of optically-absorbing media that is imbedded within the thermal transfer fluid, preferably comprising inorganic “dyes” that comprise pulverized thin film coatings or dissolved materials that are specifically designed for maximizing optical absorption. Alternatively, the chemistry of the transfer fluid can be modified to increase optical absorption, or the optically absorbing media may comprise fine powders with density preferably similar to the thermal transfer fluid, such as fine graphite powder; or, in another preferred embodiment, absorbing means within the heat transfer fluid comprise a solid absorbing element disposed along the central axis of the receiver tube's interior.

    • A luminescence concentrator (LK) may concentrate both incident direct and diffuse light by way of frequency shift and total internal reflection. It differs fundamentally from geometric concentrators. With sufficient geometric expansion of the collector plate, nearly arbitrarily high concentration can be achieved in the LK. A luminescence disperser is an apparatus which holds both directional and nondirectional incident light captive in a transparent body by way of frequency shift and total internal reflection and emits it diffusely or directionally uniformly distributed across an area by way of luminescence emission. The object of the invention is a method for the technical implementation of the LK and luminescence disperser, using zeolite crystals having a nanotube structure, into which the luminescent dyes are embedded such that they have antenna properties. Using the resulting novel structures, problems can be solved which made the technical use of LK impossible or at least considerably limited it. This results in completely novel usage possibilities for collecting and concentrating sun light and feeding it into photovoltaic systems, for converting it into electric and thermal energy in combined photovoltaic/hot water apparatuses, and for feeding it into fiber optic apparatuses.
    • 发光集中器(LK)可以通过频移和全内反射集中入射直射光和漫射光。 它与几何集中器的根本不同。 在集电板的几何膨胀充分的情况下,LK可实现几乎任意高的浓度。 发光分散器是通过频移和全内反射来保持透明体中的定向和非定向入射光的装置,并通过发光发射漫射或均匀分布在区域上。 本发明的目的是使用具有纳米管结构的沸石晶体技术实现LK和发光分散器的方法,其中嵌入发光染料,使得它们具有天线性质。 使用所得到的新颖结构,可以解决使得LK的技术使用不可能或至少大大限制的问题。 这导致了用于收集和集中太阳光并将其馈送到光伏系统中的完全新颖的使用可能性,以将其转换为组合的光伏/热水设备中的电能和热能,并将其馈送到光纤设备中。
