Abstract
Microwave probing can be used to study the charge carrier dynamics in photo-conductive materials. Such studies are of paramount importance considering the significant efforts dedicated towards photo-voltaic energy generation now-a-days. Contactless methods to quantify the generation of charge carriers in film-based materials, under the influence of light of varying intensity, are much needed to enable screening of such materials to identify the most promising candidates [1]. We describe the use of time-resolved microwave conductivity (TRMC), which is an effective and contactless technique, to study the dynamics of charge carrier generation and recombination in thin film-based conductive media. In this work, we present numerical simulations carried out in CST Microwave Studio, and a practical microwave probe setup, to extend the TRMC technique for enabling new measurement capabilities. Such microwave-based probe setup can be used in-line with bulk-fabrication processes for evaluating quality of thin-film organic photo voltaic materials in real time.
