Ideal Solar Cell Width
For a high solar module performance, the cell width is a crucial quantity.
Its optimal value can be estimated [1] with this calculator.
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.
In the sketch the different sizes are described.
The following calculator can be used to determine the ideal cell width.
VMPP = |
V |
(voltage of the cell at the MPP) |
|
jMPP = |
mA/cm² |
(current density of the cell at the MPP) |
|
wgap = |
µm |
(length of the interconnect area / dead area) |
|
Rsq,TCO = |
Ohmsq |
(sheet resistance of the TCO) |
wcell,opt = |
|
mm |
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.
VMPP = |
V |
(voltage of the cell at the MPP) |
|
jMPP = |
mA/cm² |
(current density of the cell at the MPP) |
|
wgap = |
µm |
(length of the interconnect area / dead area) |
|
Rsq,grid = |
Ohmsq |
(sheet resistance of the grid) |
|
wgridfinger = |
µm |
(width of the grid fingers) |
|
dgridfinger = |
mm |
(distance between two grid fingers) |
wcell,opt = |
|
mm |
