Since unproductive charge recombination at surface defects can limit the efficiency of hybrid perovskite solar cells, scientists can passivate the defects (induce an acid-base chemical treatment) using small molecular binding. The ionic character of perovskite lattice can allow molecular defect passivation through interactions between functional groups and surface defects. However, there exists a lack of in-depth understanding on how molecular configurations can influence passivation effectiveness to facilitate rational molecular design.&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\n Click here for original story, <a href=\"https:\/\/phys.org\/news\/2020-01-molecular-configurations-surface-defect-passivation-perovskite.html\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Constructive molecular configurations for surface-defect passivation of perovskite photovoltaics<\/a>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\nSource: Phys.org&#013;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Materials scientists aim to enable surface-trap-mediated nonradiative charge recombination to engineer highly efficient metal-halide perovskite photovoltaics (solar cells).
