Abstract: A concentrated photovoltaic receiver and backplane assembly is described herein. A thermally conductive heat spreader is configured between the receiver and the backplane for dissipating at least a portion of the thermal energy in a direction including a horizontal component towards a portion of the heat spreader which is not directly in contact with a receiver portion. In some embodiments, the heat spreader is electrically conductive and is adapted for conducting current from the receiver to the backplane. In some embodiments, a surface area of a receiver substrate is less than 5 times larger than a surface area of a solar cell that is mounted onto the receiver substrate. In some embodiments, the receiver substrate comprises vias for conducting current from a top face to a bottom face of the receiver.

Abstract: A substrate pad for soldering at least one self-aligning component thereon, wherein at least one edge of a body of the substrate pad is shaped to conform to a corresponding edge of a component pad, and the at least one edge of the body of the substrate pad further include a plurality of pad fingers leading away from the substrate pad. Related apparatus and methods are also described.

Abstract: A method of assembling an optical element on top of an active component in a substrate, by providing a substrate with active component and an optical element with a base and lateral base walls, fixating a bottom surface of a frame holder with opening and lateral frame walls arranged in a polygonal structure to the substrate so that the opening is positioned over the active component, and mounting the optical element in the opening so the lateral frame walls apply lateral confining mechanical force on the lateral base walls.

Abstract: A flexible, CPV array having high incident light conversion efficiency, the CPV array comprising: a reflective surface; a plurality of photovoltaic cells configurable to collect radiation from the reflective surface; a concentrating lens (optics) configurable to concentrate the incident light onto the reflective surface and onto the plurality of photovoltaic cells; and a conductor adapted to conduct electricity and heat from the plurality of photovoltaic cells, wherein the CPV array is exposed to incident solar radiation to generate electricity without an incident solar tracking mechanism.
