SOLAR SIMULATOR AND SOLAR CELL INSPECTION APPARATUS

摘要

Disclosed is a solar simulator having a flat-board shaped light source, wherein the measurement precision thereof is improved. Provided in one embodiment is a solar simulator provided with: an array of light sources comprising a plurality of point light-sources arranged in planar form within a certain range; an effective irradiation area to be arranged in separation from a face where the array of light sources is arranged; and a light absorption section that absorbs at least a part of the light coming from the effective irradiation area direction and passing through the gaps in between the point light-sources of the array of light sources. In one preferred embodiment, the light absorption section is an absorption layer (52) provided with an absorption face arranged on at least some of the gaps in between the point light sources. In another preferred embodiment, the solar simulator is provided with a translucent substrate (2Y) that holds a plurality of point light sources, and wherein at least some of the gaps in between the point light sources are made to be a translucent section (54). In this embodiment, a light absorption layer (56) is formed at a position where light coming from the effective irradiation area direction and passing through the translucent section can be absorbed.
