Scientists led by Cambridge University have discovered that adding a simple solution of potassium to the ink solution has the effect of 'healing' defects in metal-halide perovskite films, and immobilizing ion movement. This, according to the researchers, could push the material to higher efficiencies, while also increasing its stability.Perovksite solar cells are well known among researchers for their potential to act as cheap to produce, highly efficient solar cells. Universities and institutes the world over are working on solutions to the stability and sensitivity issues that have so far ...Den vollständigen Artikel lesen ...
