<P>PROBLEM TO BE SOLVED: To provide a liquid cooling type light condensing solar battery which can efficiently cool the entire power generation element, and can be increased in size, without degrading durability, by improving mechanical strength of a device and preventing thermal deformation. <P>SOLUTION: The light condensing solar battery includes a battery case 1 which is a case consisting of an upper plate 11 equipped with a condensing lens part 11a, a bottom plate 12 having heat propagation nature, and side plates 13, with a liquid feeding opening 14 capable of supplying a coolant C to the interior; and a power generation element 2 which is secured to the bottom plate 12 of the battery case 1 and is irradiated with light condensed through the coolant C from the condensing lens part 11a of the upper plate 11. Projection type long fins 12a, 12a, etc. of such length as to abut with or approach the upper plate 11, are arrayed on the bottom plate 12 of the battery case 1. Meanwhile, below the condensing lens part 11a, short fins 12b, 12b, etc. of such length as not to reach a light condensing region are arrayed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
