Solar Simulator and IV Measurement System
It is a continuous simulated light source used to measure the efficiency of single & multi crystalline silicon solar cell, thin-film solar cell, dye-sensitized solar cell, III-V solar cell and organic solar cell. This simulator can be upgraded to dual lamp system or IV measurement system.
Simulator Performance Standard Photovoltaic (PV) cells, like single & multi crystalline silicon, thin-film, dye-sensitized, III-V and organic solar cells are required to have highly efficient performance. Hence, a simulated light source becomes a standard for testing laboratories.
According to photovoltaic standard, ASTM E927, a simulator is classified by three characteristics: spectral match, non-uniformity of irradiance, and temporal instability of irradiance. ASTM E927 also indicates the spectral distribution from 400-1100nm is the classification of solar stimulation.
Spectral Match simulator refer to ASTM G173, which defines the reference spectral distribution of sunlight at global Air Mass 1.5. The spectral match is defined as a percentage of the integrated intensity in 6 spectral ranges. The deviation from 0.75 to 1.25 in each range is classified as class A simulator; 0.6 to 1.4 is class B simulator.
