<P>PROBLEM TO BE SOLVED: To provide a reliable concentrator photovoltaic unit which is improved in photoelectric conversion efficiency by improving the heat dissipation property of a solar battery (solar battery element) by generating an atmospheric convection in a space on the light-receiving surface side of the solar battery element, and also to provide a concentrator photovoltaic system equipped with the same. <P>SOLUTION: The concentrator photovoltaic unit 1 includes a condensing frame 20 having a transmission hole 23 to transmit solar light Lsa condensed by a condenser lens 10, a solar battery 30 which receives the solar light Lsa transmitted through the transmission hole 23, and a mounting frame 40 on which the solar battery 30 is mounted. The condensing frame 20 includes a pair of opposing side plate portions 21 for supporting the condenser lens 10 and a bottom plate portion 22 which is disposed between the pair of opposing side plate portions 21 and has the transmission hole 23. The mounting frame 40 includes: a mounting plate portion 41 for mounting a receiver substrate 32; and coupling portions 42 which are disposed on both sides of the mounting plate portion 41 and couple the mounting plate portion 41 to the bottom plate portion 22. <P>COPYRIGHT: (C)2010,JPO&INPIT |
