Polaron formation in perovskite solar cells has been indicated in scientific research as a possible factor for making this kind of cell particularly efficient, although the mechanism behind ...

In a polaron, an electron and the lattice distortion that it induces in a crystal form a 'quasiparticle'. But a strong electric field can displace the two constituents with respect to each other ...
