Charge carriers in methylammonium lead perovskite solar cell absorbers assume a combined (hyper‐) polaronic state combining a classical Fröhlich polaron with a micelle‐like arrangement of electric dipoles formed by the methylammonium ions. This “micellion” provides an extra contribution to the dielectric constant which screens defects but maintains mobility of the polaron. This is reported by Doru C. Lupascu and co‐workers in article number 1700600. In the image, the structure of the hyperpolaron is shown.

太阳能电池：介电响应：甲基铵卤化铅铅太阳能电池吸收器中的许多问题的解答（Adv。Energy Mater。19/2017）

甲基铵铅钙钛矿太阳能电池吸收器中的载流子呈现组合的（超）极化子态，将经典的Fröhlich极化子与由甲基铵离子形成的胶束状电偶极子结合在一起。这种“胶束”为介电常数提供了额外的贡献，该介电常数屏蔽了缺陷，但保持了极化子的迁移率。这是Doru C. Lupascu及其同事在文章编号1700600中报告的。在图像中，显示了超极化子的结构。
