Title:
SOLAR SIMULATOR AND SOLAR CELL INSPECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/152081
Kind Code:
A1
Abstract:
Disclosed is a solar simulator wherein locational unevenness of irradiance is minimized by employing a small and simple optical assembly. Provided is a solar simulator (10) comprising: an array of light sources (2), further comprising a plurality of point light sources arranged in a planar shape in a range (24); an effective irradiance region (4) that is positioned at a remove from the plane in the array of light sources (2) whereupon the point light sources (26) are arranged; and reflecting mirrors (6) that are positioned so as to encompass the range (2) of the array of light sources. It is preferable that a distance L, between point light sources located at the outermost part of the range (24) of the array of light sources (2) and the reflecting surfaces of the reflecting mirrors (6), be half of a pitch a of the array of point light sources, and it is more preferable that the distance L be more than half a width b of each respective point light source, as well as less than half of the pitch a of the point light sources.
