Perovskite Publication Reaching Record Efficiency by ODTÜ-GÜNAM Researchers

The study entitled “Efficient and Stable Inverted Wide-Bandgap Perovskite Solar Cells and Modules Enabled by Hybrid Evaporation-Solution Method”, co-authored by ODTÜ-GÜNAM Emerging Photovoltaic and Test-Characterization Divisions’ researchers, has been published in the journal “Advanced Functional Materials” having a high-impact factor.

The study evaluated the efficacy of the hybrid evaporation-solution method (HESM) in the production of stable, efficient, and scalable wide-bandgap perovskite solar cells (WBG-PSCs).

The resulting perovskites exhibited impressive performance, with record efficiencies of 21.06% and 20.35% in cells and 19.83% and 18.73% in mini-modules (16 cm2) for bandgaps of 1.64 and 1.67 eV, respectively. These efficiencies are among the highest reported for wide-bandgap (>1.6 eV) perovskite solar modules in the literature for their respective areas.

The findings demonstrate the significant potential of HESM in the production of stable, efficient, and scalable WBG-PSCs for use in emerging applications such as indoor photovoltaics.
