Abstract

Disclosed is a device for generating simulated solar light, wherein a switching system is adopted that makes it possible to provide a larger amount of power, that makes it possible to measure the I-V characteristic of a solar battery accurately and with high efficiency, and that makes it possible to increase the time for which arc discharge of a lamp is maintained. Power is supplied to a double-layer accumulator and power control circuit (20) from a charging power source (12) connected with a mains power source (11), and charging is performed by charging control by a control circuit (70). Then, when charging of the double-layer accumulator and power control circuit (20) is completed, a flash lamp (50) is switched on by charging a smoothing capacitor (38) with a prescribed voltage, using the control circuit (70) to control a switching-type power source voltage boosting circuit (30).

Description

technical field [0001] The present invention relates to a presudo sunlight generation device and a presudo sunlight generation method for measuring solar cell characteristics. Background technique [0002] Conventionally, in the measurement of the I-V characteristics of solar cells, a method of irradiating simulated sunlight and measuring the I-V characteristics of the solar cells at that time has been used. [0003] figure 1 It is an explanatory diagram showing a DC lighting discharge lamp lighting device 100 used in the prior art (see Non-Patent Document 1). Such as figure 1 As shown, the DC lighting discharge lamp lighting device 100 is composed of a lamp, an igniter that starts the lamp (dielectric breakdown) and transitions to an arc discharge, and a lighting device that controls the lamp current to maintain the arc discharge. [0004] also, figure 2 It is a graph showing the relationship between the elapse of time, the lamp current and the lamp voltage. exist f...
