For a high solar module performance, the cell width is a crucial quantity.
Its optimal value can be estimated [1] with this calculator.
Modules without Grid
The first calculator is for modules with only a TCO layer on top.
In the sketch the different sizes are described.
The following calculator can be used to determine the ideal cell width.
Modules with Grid
The second calculator is for modules with a grid layer on top of the TCO layer.
In the sketch the different sizes are described.
The following calculator can be used to determine the ideal cell width.
