I am trying to extract the single diode lumped parameters of an a-si/μc-Si PV module. To analyze them at a cell level, I have to know how the cells' interconnections are, but the datasheet does not provide that information. Here, the datasheet: https://www.energymatters.com.au/images/sharp/sharp-na-f128gk.pdf (SHARP Na-f128GK). Thanks a lot!
you can deposition amorphous (a-Si:H) and microcrystalline (μ c-Si : H )
the parameters are
-the broader absorption spectrum of material.
- mitigating the nanocracks
-cells are grow on a smooth substrate with large periodicity
- strongly scatter of a-Si:H material.
-The intermediate reflector uncouples the growth and light scattering
Dear Miguel Angel Sevillano-Bendezú ,
welcome!
The number of cell in the tandem module is 180 cell. So, in order to get the the the characteristics of one cell you need only to scale the characteristics of the voltga eof the module by 180.
You will get the one cell I-V curve. Then you extract the parameters from this single characteristics.
The other method is to obtain the parameters of one cell from the whole tandem module assuming Ns= 180.
For more information please refer to the book chapter:Chapter Solar cells and arrays: Principles, analysis and design
