    • Device for harvesting light from a light source, comprising: First photovoltaic cell having an upper surface, a lower surface, and an array of optical passages therein. Array of optical concentrating elements above the upper surface defining a light acceptance area, each being associated with one of the optical passages, and being structured/arranged to concentrate direct light towards theretowards. Concentrated direct light passing through the first photovoltaic cell via an optical passage and exiting as a non-parallel light beam. Array of optical redirecting elements below the lower surface, each being associated with one of the optical passages; each receiving the light beam from the optical passage with which it is associated and redirecting it optically towards a second photovoltaic cell. Diffuse light passing through the array of optical concentrating elements to upper surface of first photovoltaic cell. Second photovoltaic cell having an active area being smaller than the light acceptance area.
    • 用于从光源收集光的装置,包括:具有上表面,下表面和其中的光学通道阵列的第一光伏电池。 在上表面上方的光学聚集元件阵列限定光接收区域,每个光接收区域与光通路中的一个相关联,并且被构造/布置为将直接光朝向其中。 集中的直接光通过光通路穿过第一光伏电池并作为非平行光束离开。 在下表面下方的光学重定向元件的阵列,每个与所述光学通道中的一个相关联; 每个光束从与其相关联的光学通道接收光束并将其光学地转向第二光伏电池。 通过光聚集元件阵列的漫射光到第一光伏电池的上表面。 第二光伏电池具有小于光接收面积的有效面积。
