Solar Cells: Dielectric Response: Answer to Many Questions in the Methylammonium Lead Halide Solar Cell Absorbers (Adv. Energy Mater. 19/2017)
Source abstract
Abstract
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.
