Personal page Nikolaos Felekidis

I received my bachelor degree in Electrical and Computers in 2009 from Aristotle University of Thessaloniki, Greece. My specialization is in micro-processors and robotic applications.

I obtained my Master degree in Biomedical Engineering from Linköping University, Sweden in 2012.
In 2014 I was offered a position as a PhD student in the ”Complex Materials and Devices” group of the Physics, Chemistry and Biology (IFM) department of Linköping University. My supervisor is Professor Martijn Kemerink. I will be studying injection, motion and recombination mechanisms in OPV in the frameset of different characteristic material parameters. 

Specific projects

- Study of charge carrier dissociation efficiency

The internal quantum efficiency (IQE) is simulated and studied with respect to different parameters such as initial delocalization of the e-h pair, energetic disorder and device morphology.

- Simulation of ternary OPV

The tunability of the open circuit voltage (Voc) via the control of the D:D or A:A ratio is simulated. Simulation data are used to fit experimental data for ternary bulk heterojunction organic solar cells. Implementation of a simple optics models allows asseesment of the PCE and proposed design rules for DDA ternary OPV.
