EKO advanced AAA solar simulators are based on a high power xenon lamp combined with precision optics and optical filters to match the AM1.5 Solar Spectrum. The Irradiance output can be control through an integrated control unit and measurement processing unit. Light intensity can be maintained very stable using closed loop intensity control which continuously monitors the light variance of lamp. This solar simulator is typically used for reserach & development applications to characterize and optimize solar cells.
The performance characteristics of solar simulator for solar cell evaluation is defined within JIS C8912 (crystalline)* and JIS C8933 (amorphous)*, describing the classifications (A~C Class) and measurement methods for spectral irradiance, irradiance non-uniformity, and temporal instability of irradiance.
EKO Solar Simulator series comply with the highest JIS standards and are available with different beam dimensions respectively 50 x 50 mm and 156 x 156 mm. Besides the stand alone sun simulators EKO provides indoor turn key systems for cell performance testing.

*1 Depending on how the solar simulator is used, the lamp lifetime will vary. (Example: if the lamp is turned ON and OFF frequently, the lamp lifetime becomes shorter)
*2 Indicates the irradiance adjustment range at the time of shipping inspection. Depending on the used time, the irradiance adjustment range may not be satisfied.
