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,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; and
a light absorber that absorbs light originating from the array of emitters redirected from the effective irradiated region and passing through gaps between the individual point light emitters of the array of light emitters.

Abstract
A solar simulator having improved measurement precision, including an array of light emitters having point light emitters planarly arranged in a given range, an effective irradiated region spaced apart from a surface having the array thereon, and a portion which absorbs at least a part of light from a direction which passes through a gap between the individual point light emitters. In a preferred aspect, the light absorption portion includes an absorption surface disposed in at least a part of the gaps between the light emitters. In another preferred aspect, a translucent board holds the light emitters and has a translucent portion corresponding to at least a part of the gaps between the light emitters, and an absorption layer at a position for absorbing light from the direction which passes through the translucent portion.
