Problems solved by technology

[0008] However, although it is theoretically possible to configure such a filter unit, it is very troublesome to install a mesh filter on the area corresponding to the part with high irradiance on the solar panel.
For example, when the light-emitting state of a light-emitting lamp changes over time, etc., it is difficult to change the position of the mesh filter to correct the newly-occurring irradiance unevenness.
[0009] In addition, even if the above-mentioned filter unit is used, it is difficult to reduce the irradiation unevenness to the level allowed by the A class stipulated in the standard.

Abstract

Theinvention provides a solar simulatorwhich is simple in structure and can greatly reduce irradiation unevenness of an irradiation object, for example, the solar simulator can satisfy supreme grade standard. The solar simulatorcomprises a luminescent lamp (1) in an annular shape, a workpiece (W) used as the irradiation object is configured on a cut-through direction of a ring, and an annular shielding body (21) which is formed by wire rods and is disposed between the luminescent lamp (1) and the workpiece (W).

Description

technical field [0001] The present invention relates to a solar simulator used for performance evaluation of solar battery cells and other light resistance environment evaluations. Background technique [0002] For example, in performance evaluation of a solar battery cell, JIS C8912 and IEC60904-9 define standards for the unevenness of irradiation of light irradiated on the surface of a solar battery cell to be irradiated. More specifically, the irradiance non-uniformity (irradiance unevenness due to different positions) is defined by the following formula. [0003] (Formula 1) [0004] ΔE = ± E max - E mim E max + E min × 100 [0005] Among them, ΔE: irra...
