Bypass diode
The junction boxes used with the photovoltaic modules contain bypass diodes
connected in parallel with the rows of photovoltaic cells.
In the case of partial shading, the diodes divert the current generated by
the unshaded cells, thus limiting the heating of the module and the loss of
performance.
Bypass diodes are not overcurrent protection devices. Bypass diodes divert
current from cell strings in the event of partial shading.
See the figure below that shows how the cell strings are connected to the diodes.
