Measurement Types

The Solar Cell I-V software can perform 3 different types of measurements. Each measurement
type can be selected using the tabs at the top of the window. The available measurements are:
1. Characterisation (Section 9.1.1).
2. Lifetime (Section 9.1.2).
3. Stabilised Current (Section 9.1.3).
Each measurement type requires several settings to be selected before it can be performed.
Settings that are shared between all measurements are detailed in Section 9.3. Measurement-
specific settings are detailed in Sections 9.4, 9.5, and 9.6.
9.1.1 Characterisation
The Characterisation tab performs current-voltage (I-V) measurement and analysis of solar cells.
The analysis calculates the following properties:
Power conversion efficiency (PCE)
•
Fill factor (FF)
•
Short-circuit current density (J
•
Open-circuit voltage (V
•
Shunt resistance (R
•
Series resistance (R
•
Maximum power (P
