Doctoral studies at FEE were essential for my current profession. After mastering various experimental techniques, literature searches, and numerous professional discussions with my supervisor and colleagues, I identified my favorite topic - photovoltaics. More importantly, my supervisor taught me to look at research from a creative angle, as if I were "creating a story". It was fun (though sometimes very challenging) to combine imagination, logic, laws of nature, and actual knowledge to develop new research topics, materials, and experimental methods.
