Consider a small module based on interconnected tandem cells of hydrogenated amorphous and microcrystalline silicon as depicted in the figure below. The \(V_{oc}\) of a single tandem cell is \(1.35 V\) and the short-circuit density \(J_{sc}\) is \(12 \,mA/cm^2\).Which combination of the external parameters can reflect the external parameters of the module depicted in the figure above?

A. ) \(V_{oc,module}=16.2V\), \(I_{sc,module}=60mA\)
B. ) \(V_{oc,module}=16.2V\), \(I_{sc,module}=120mA\)
C. ) \(V_{oc,module}=32.4V\), \(I_{sc,module}=720A\)
D. ) \(V_{oc,module}=32.4V\), \(I_{sc,module}=120mA\)
