ABSTRACT
ABSTRACT: Impedance spectroscopy is a non-destructive technique with high sensitivity to small changes in the electrical response of a device of interest. This technique has been used to determine the dynamic (AC) characteristics of solar cells. The knowledge o f the AC characteristics is of high importance for the efficient action o f switching charge controllers. A mismatch can lead to reduced performance of the whole power generating system. The AC characteristics of the solar cell are depending on ambient conditions, in particular on illumi nance and temperature. The knowledge of those characteristics can be used to optimize the performance of the complete system.
