Characterisation
| A range of Solar Simulators and Source Measure Units are available at the FEL for the evaluation of Power Conversion Efficiency (PCE) of devices or modules having active areas from 0.1 cm2 to ~1,000 cm2. |  |
| Maximum Power Point (MPP) tracker for the stability and lifetime analysis of small-area devices and mini-modules (geometric area ~100 cm2). |  |
| Our in-house built Light Beam Induced Current (LBIC) imaging (also known as photocurrent mapping) system is a well-established method for the analysis of recombination-active defects and degradation mechanism of printed photovoltaics cells and modules. |  |
| Outdoor stability and operational lifetime studies of mini-modules (~100 cm2) are conducted at the FEL in CSIRO (Clayton) using a solar cell assessment rig designed and constructed in-house. This system enables frequent I-V measurements of devices/modules installed on a North-facing panel for evaluating performance under real outdoor conditions. |  |
