The WCT-100 photoconductance instrument is used throughout the photovoltaic industry providing a relatively simple and inexpensive means to assess recombination parameters. This paper presents a method to determine its output voltage VWCT over the conductance range, S = 0002-20mS, a range not easily attained by the conventional calibration method. The relationship between VWCTand S is found to transition from being non-linear to linear at S ∼ 1 mS, which equates to the conductance of a 300 μm...[Show more]
