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, e

Embodiment Construction

[0038] refer to Figure 1 to Figure 5 The solar simulator 100 according to the first embodiment of the present invention and the solar cell evaluation device 200 using the solar simulator 100 will be described.

[0039] figure 1 The solar battery cell evaluation apparatus 200 of the first embodiment shown is used, for example, to evaluate output characteristics of solar battery cells W in a manufacturing stage, and to classify solar battery cells W according to characteristics.

[0040] The solar cell unit evaluation device 200 is as figure 1 As shown, it includes: a solar simulator 100 in a roughly cuboid shape, which irradiates pulsed light to a solar battery unit W as an irradiation object and as a workpiece; W; I-V tester TS, which measures the voltage value and current value output from the solar battery unit W, thereby measuring and evaluating the I-V characteristics; and lighting power supply P, which controls the lighting timing and lighting of the solar simulator 10...

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...
