A Solar Simulator is a light source that approximates the illumination of natural sunlight. Solar simulators with various tailored spectral output are used to test a variety of samples including but not limited to solar cells, materials photo-stability, and other samples (in-vivo or in-vitro) under controlled, repeatable, laboratory conditions. OAI Solar Simulator is certified for Class AAA performance having aperture sizes of 156 mm × 156 mm for 0-4 SUNS with long working distance (~22 inches). It has CPVLD50 adaptor light pipe for 20 SUNS (aperture size: 45 mm × 45 mm) and 50 SUNS (aperture size: 25.4 mm × 25.4 mm) measurement (working distance of ~2 mm). The equipment uses I-V-Rider software which record I-V data in both forward and reverse sweep directions. It also allows calculation of various solar cell parameters such as short circuit current (I_sc), short circuit current density (J_sc), open circuit voltage (V_oc), maximum voltage (V_max), maximum current (I_max), maximum power (P_max), cell efficiency, series resistance (R_s) and shunt resistance (R_sh).

Quantum efficiency (QE) and Incident Photon to Charge Carrier Efficiency (IPCE) indicates the ratio of the number of photons incident on a solar cell to the number of generated charge carriers. Oriel Instrument's IQE-200 series system measures the External Quantum Efficiency (EQE) and Internal Quantum Efficiency (IQE) of solar cells, detectors, or other photon-current devices. It covers the spectral ranges of 300 – 1100 nm and 300 – 1800 nm, for both AC and DC operation.
