Solar Simulator

A solar simulator produces light close to standard sunlight (1 sun, 1000 W/m², AM1.5G spectrum) so that solar cells can be tested under controlled, repeatable conditions. Together with an I-V test system it gives the four numbers every solar cell paper reports: open-circuit voltage (Voc), short-circuit current density (Jsc), fill factor (FF) and power conversion efficiency (PCE).

What a complete test setup needs

  • Light source: Ossila LED Solar Simulator G2009B2 (class AAA over a 15 mm diameter area, ABA over 25 mm; LED lifetime up to 10,000 h) or its lamp unit G2009A1; ABET Technologies 10500 low-cost solar simulator.
  • I-V measurement: Ossila Solar Cell I-V Test System T2002F2 (±10 V, current ranges ±10 nA to ±200 mA) with forward and reverse sweeps for perovskite hysteresis; the A2006A1 bracket mounts the simulator over the automated test board.
  • Calibration: a reference cell to set 100 mW/cm² at the sample plane before every session. Without it, efficiency values cannot be defended.

How to choose

Match the area where the simulator reaches the class you need to your device size, choose steady-state (continuous) light for perovskite, organic and dye-sensitized cells, and check that the I-V system's voltage and current ranges suit your devices.
