Areas of expertise

Perovskite solar cells, flexible solar cells, atomic force microscopy, impedance spectroscopy

Research

My research is focused on the adaptation of bio-based films as substrates for flexible perovskite solar cells. The aim is to improve their recyclability by substituting glass for a bio-based film.
