Welcome to the Turak Research Group!

Our research focusses on easy, versatile, and inexpensive methods of exploring and tuning interfaces in organic/perovskite/hybrid photovoltaics and light emitting diodes to tackle critical problems in stability, lifetime, and manufacturing.

To achieve this vision, we use simple manufacturing approaches (reverse micelle deposition of nanoparticles), allow nature to dictate morphology (entropic self-assembly, beneficial dewetting), and develop widely applicable tools (“dis-Locate” spatial order classification package,“MORPHOLOGIES” Monte Carlo simulation code, 3D printed environmental testing chamber).
