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
9.1.1
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
sc
)
•
Open-circuit voltage (V
oc
)
•
Shunt resistance (R
sh
)
•
Series resistance (R
s
)
•
Maximum power (P
