Several settings used by the Solar Cell Utility in computing the Solar Cell Efficiency (%) include the Global Collection Efficiency, the Open Circuit Voltage, and the Filling Factor.
- The Global Collection Efficiency (GCE) represents the efficiency at which generated electron-hole pairs are captured by the electrodes within the device. There are generally two methods to compute this quantity: 1) Perform a complete electronic simulation via RSoft's LaserMOD™ simulation tool, or 2) Fit the simulation results found with the Ideal Diode electronic model to experimental data. Here, we have used the Ideal Diode model utilizing the experimental data in Ref  to compute the GCE.
- For this application note, the values for the Open Circuit Voltage and Filling Factor were obtained directly from Ref .
The Solar Cell Efficiency results at varying incident light intensities, as shown in Fig 2, agree well with Fig 3 in . For a more detailed study of this structure, it would be necessary to use the LaserMOD electrical model.
