Electrical characterization of thin film solar cells and absorbers

CHEETAH WEBINAR

Dr. Stephan Buecheler 10th  May  2017
11:00 –12:10 CEST
 
Dr. Thomas P. Weiss

Characterization of thin film solar cells exhibits a number of challenges compared to Si solar cells. Recombinative interfaces, band alignment and barriers for example caused by hetero interfaces, may have a great impact on various measurements. Being aware of these complications will help in drawing false conclusions from measurement data.

The course will cover the following topics and analysis procedures

  • IV – Current – Voltage: the evaluation of the IV curve in the framework of the 1-diode model. Deviations from the 1-diode model.
  • CV – Capacitance voltage: the analysis of the built-in voltage and the doping density by analyzing the voltage dependence of the capacitance
  • TAS – Thermal admittance spectroscopy: the detection of deep defects within in the bulk of the absorber and possible barriers in the solar cell structure
