SOLAR SIMULATOR AND SOLAR CELL INSPECTION DEVICE
First Claim
1. A solar simulator comprising:
- an array of light emitters having a plurality of point light emitters arranged in a plane in a given range; and
a reflection mirror disposed to surround the given range in the array of light emitters,wherein light from the array of light emitters is incident upon an effective irradiated region spaced laterally apart from the given region of the plane, and at least a part of the effective radiated region corresponds to a light receiving surface of a target solar cell to be inspected.

Abstract
A solar simulator in which locational unevenness of irradiance is reduced by using a small and simple optical system, having an array of light emitters 2 with a plurality of point light emitters planarly arranged in a given range 24, an effective irradiated region 4 spaced apart from a surface having the point light emitters 26 arranged thereon, and a reflection mirror 6 disposed to surround the given range 24 of the array. Preferably, a distance L between the point light emitter positioned at the outermost portion of given range 24 of the array of light emitters 2 and a light-reflecting surface of the reflection mirror is half of a pitch a of the array of the point light emitters and, more preferably, the distance L is larger than half of a width b of each point light emitter, and smaller than half of the pitch a.
