The properties of a defect and its impact on the material quality are of great importance for the efficiency of solar cells.
The properties of a defect and its impact on the material quality can be described by three main parameters:
defect concentration NT
capture cross sections for electrons and holes σn, σp
activation energy ET
All this properties are part of the simulation models we use and aside from the defect concentration can be measured with the temperature dependent method MD-PICTS.
