Investigation of Carrier Dynamics in Templated Perovskite Films with Different Densities of Nanopores

Carrier dynamics in templated perovskite films with different densities of nanopores were investigated. We employed colloidal solution processing to obtain templated perovskite films with different number densities of nanopores. X-ray diffraction (XRD) and photoluminescence (PL) measurements confirm...

Zusammenfassung:	Carrier dynamics in templated perovskite films with different densities of nanopores were investigated. We employed colloidal solution processing to obtain templated perovskite films with different number densities of nanopores. X-ray diffraction (XRD) and photoluminescence (PL) measurements confirmed that porous structures dominantly influence a fast carrier decay process such as carrier extraction, while PbI2 residuals influence a slow carrier decay process.
