Here, we show that quaternary ammonium halides can effectively passivate ionic defects in several different types of hybrid perovskite with their negative- and positive-charged components.

The results demonstrated that the treatment works at high concentrations, which is typically needed to passivate surface defects over time, and that it could be applied without damaging the ...

A new study from Australia has highlighted the potential of polysilicon passivated junctions for revolutionizing the commercial production of crystalline silicon solar panels. It also presented ...
