TL;DR: In this article, the binding energy of correlated two-electron, two-hole quasiparticles was determined to be $44.5$ meV at room temperature.

TL;DR: Examination correlation photoluminescence (ECPL) spectroscopy is used to investigate the recombination dynamics of the photogenerated carriers in lead bromide perovskites and quantitatively describe the carrier trapping dynamics within a generalization of the Shockley-Read-Hall formalism.

TL;DR: In this article, the structural and photo physical properties of semiconductor nanocrystals have been investigated and a model for the ultrafast response of gold nanoparticles has been proposed, which is successfully interpreted by adapting models of the ultra-fast response.

TL;DR: In this article, the binding energy of correlated two-electron, two-hole quasiparticles was determined to be $44 \pm 5$\,meV at room temperature.

TL;DR: This work investigates the effect of an applied external electric field on the photoexcited species of CH3NH3PbI3 thin films, both at room temperature and at low temperature, by monitoring the photoluminescence yield and PL decays and assigns this to field-induced alignment of the molecular dipoles, which reduces the vibrational freedom of the lattice and the associated local screening and hence results in a stronger electron-hole interaction.
