Scientists in the United States took a closer look at the way charges move through a perovskite material, and found that replacing hydrogen in the material with a heavier isotope can both reduce thermal conductivity and increase carrier lifetime, potentially leading to more efficient solar cells. And the group expects continuing study of charge states and molecule dynamics to yield further important discoveries.Despite their recent popularity among researchers in photovoltaics, there is still plenty that we don't understand about perovskite materials. And an understanding of interactions and ...Den vollständigen Artikel lesen ...
