In MOSFET, the capacitance is related to voltage through the formula C=dQ/dV. Is this voltage (dV) across the capacitor or between electrode and gnd?

In MOSFET small signal analysis, we can relate charge (Q) and capacitance (C) using the formula Cij = dQi/dVj. Is the voltage term (dVj) calculated across the electrode terminals 'i' and 'j' ? Or...

Why use MoOx/Ag instead of MoOx/Au in inverted organic solar cells?

May I know why most literature, including yours, use ITO/ETL/P3HT:PCBM/MoOx/Ag configuration instead of .../MoOx/Au configuration? Does MoOx/Ag have any workfunction advantage over MoOx/Au (Since...
