Research Focus:

Our research is concentrated on the design and production of new excitonic solar cells, combining radically new materials with novel architectures.

Specific topics related to materials science and photovoltaic cells are:

  • Two-dimensional perovskite and its application in solar cells
  • Carbon based perovskite solar cells
  • Organic-inorganic perovskite nanostructures – synthesis, optical and physical properties
  • Inorganic perovskite nanostructures
  • Light emitting diode (LED) based on hybrid and inorganic Perovskite
  • Semi-transparent perovskite solar cells
