AN-PV-002
Photovoltaics part 2 – dye sensitized solar cells, impedance measurements
Tóm tắt
DC techniques do not provide any information about the internal dynamics of the PV device. Therefore, additional information can be obtained using time-dependent and frequency-dependent measurements. Electrochemical impedance spectroscopy in particular, offers the possibility to investigate the behavior of the device in the frequency domain under operating conditions, at various light intensities.
