On Mott-Schottky analysis interpretation of capacitance measurements in organometal perovskite solar cells [PDF]
Capacitance response of perovskite-based solar cells (PSCs) can be exploited to infer underlying physical mechanisms, both in the materials bulk and at outer interfaces. Particularly interesting is applying the depletion layer capacitance theory to PSCs,
