In this project we aim to increase the overall performance of the Perovskite Solar Cell (PSC) by introducing two novel approaches. The first approach refers to the synthesis of new advanced carbon-based materials and their integration in PSCs which will lead to improved charge transport, reduced defects, suppressed carrier recombination and facilitate the perovskite crystal growth, either as additives in perovskite materials or as modification at the interfaces ETL/ Perovskite and Perovskite/ HTL. The second approach concerns the PSC with the highest efficiency in which further optimization will be addressed by exploiting the superior stability of 2D perovskites. 2D perovskites can be combined with 3D perovskites into a 2D/3D hybrid system, increasing both the efficiency and stability of the devices.

The main objectives of this project comprise: Composition and characterization of carbon-based nanostructured materials, such as carbon graphite nitride derivatives (g-C3N4).

Synthesis and characterization of metal oxides and nanoparticles of Fe2O3, Fe3O4, WO3 and their combination (core-shell) with the innovative g-C3N4. 

Amplification (doping) of carbon with metal oxides (Fe2O3, Fe3O4, WO3) as it is expected to positively affect the charge transfer properties, shifting the energy zones, improving the conductivity of electrons and reducing electron-hole reconnection. 

The development and electrochemical characterization (IPCE, J-V, EIS, MPPT, mobilities) of innovative high-performance perovskite solar cells using the new materials. 

Integration of 2D perovskites into PSCs as a 2D/3D hybrid stabilizer component.
