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.
Description
technical field [0001] The present invention relates to a solar simulator and a solar cell inspection device each for inspecting a solar cell. More particularly, the present invention relates to a solar simulator using a light emitter array including point light emitters, and a solar cell inspection device using the solar simulator. Background technique [0002] Conventionally, in order to check the photoelectric conversion characteristics of produced solar cells, the electrical output characteristics of the solar cells are measured when the solar cells are irradiated with predetermined light. In this measurement, a light emitter device for irradiating a solar cell with light satisfying a predetermined condition, ie, a solar simulator, is used. [0003] In solar simulators, in order to generate illumination light with a spectrum similar to sunlight, in many cases illuminants with suitable filters, such as for example xenon lamps or halogen lamps, are used as light emitters....
