Current Voltage Measurement Solar Simulators

Irradiation of pseudo sun

The Model OTENTO-SUN II Solar Simulator employing the Xenon lamp and AM1.5G filter irradiates pseudo solar light on the sample such as a solar cell to evaluate its characteristics. The Model OTENTO-SUN Ⅱ conforms to the Japanese Industrial Standard (JIS ) and is ranked into Class AAA which is the best according to the classifications of grades in JIS.

Optional filters are set on the Model OTENTO-SUN Ⅱ, which can beused for the following purpose.

1. Linearity of the light intensity of the sample when using the ND filter

2. Irradiation of monochromatic light by the color filter

This model is superior in stability of light intensity with the feedback system monitoring it in a real time employing a constant irradiation power supply.
