nanostructure and photo-transport mechanisms has become of crucial importance for the development of many emerging photovoltaic technologies. In this context, Kelvin probe force microscopy under frequency-modulated excitation has emerged as a useful technique for probing photo-carrierdynamics and gaining
experimental results as additional information about the photo-carrierdynamics of the sample can be gained via the numerical analysis.

dynamics; Introduction
In the past decade, the nanoscale investigation of materials properties has captured the attention of the scientific community, partially due to its crucial importance in the improvement of photovoltaic devices [1][2]. Carrier lifetime, or more broadly speaking, photo-carrier
