説明

<jats:title>Strong perovskite interfaces</jats:title> <jats:p> The weak bonding in the crystal lattice of hybrid perovskites used in solar cells promotes surface decomposition and interferes with the formation of stable heterostructures with the charge carrier layers. Y. Wang <jats:italic>et al.</jats:italic> show that strong bonds are formed between lead and both chlorine and oxygen atoms in a film with a lead-rich surface and a chlorinated graphene oxide layer. This interface was used with common hole-transporting materials to fabricate solar cells that maintained 90% of their initial efficiency of 21% after operation at 60°C for 1000 hours. </jats:p> <jats:p> <jats:italic>Science</jats:italic> , this issue p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6454" page="687" related-article-type="in-this-issue" vol="365" xlink:href="10.1126/science.aax8018">687</jats:related-article> </jats:p>
