    • The present application describes embodiments of a non-tracking solar energy collector comprising: (a) at least one solar radiation concentrator for collimating and directing the incident solar radiation rays to at least one focal point along the surface of a reactive reflector; (b) the reactive reflector mounted on top of an external cavity and having at least one transparency zone instantly formed at said at least one focal point of the solar radiation rays, for letting the solar radiation rays enter said external cavity, wherein said transparency zone is constantly moving along the surface of said reactive reflector following the position of said at least one focal point of the solar radiation rays; and (c) the external cavity containing a solar cell and capable of trapping the entered solar radiation rays by inner scattering of said solar radiation rays on the walls of said external cavity, wherein said inner scattering of said solar radiation rays inside said external cavity is preventing solar radiation to escape from said solar cell, thereby minimising solar radiation losses.
    • 本申请描述了非追踪太阳能收集器的实施例,其包括:(a)至少一个太阳辐射集中器,用于将入射太阳辐射射线准直并引导至沿表面的至少一个焦点 的无源反射器; (b)安装在外部空腔顶部并且具有至少一个立即在太阳辐射射线的所述至少一个焦点处形成的透明区域的反应性反射器,用于使太阳辐射射线进入所述外部空腔,其中所述透明区域 不断沿着所述无功反射器的表面跟随所述太阳辐射射线的所述至少一个焦点的位置移动; (c)包含太阳能电池并且能够通过所述太阳辐射射线在所述外腔的壁上的内散射来俘获进入的太阳辐射射线的外腔,其中所述外腔内的所述太阳辐射射线的所述内部散射是 防止太阳辐射从所述太阳能电池逸出,从而使太阳辐射损失最小化。
