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.
