Effects of lateral resistances in photovoltaic cells and full 2-D parameter extraction for the spatially-resolved models using electroluminescence images
conference contribution

lateral resistances in photovoltaic (PV) devices,
and proposes a method for extracting local
electrical parameters of thin-film PV devices
based on a 2-D spatially-resolved model
utilising electroluminescence (EL) images and
2-D fittings. PV-oriented nodal analysis
(PVONA) is used for studying the electrical
properties of the devices and for simulations in
iterative 2-D fitting processes. It is shown that
the effects of the lateral resistances should not
be simply replaced by lumped effective
resistances. The proposed new method
employs firstly the dark-I-V fitting for the
junction parameters; and secondly 2-D fitting
of EL images taken under varying bias levels,
for the internal and lateral series resistances.
The method is verified by a case study and
demonstrates excellent agreements with
measurement data.
