Abstract
Organic-inorganic hybrid perovskite materials based on metal-organic structures are attracting much attention, as they are characterized by rather high photocurrent conversion together with comparative simple production procedure. A model analysis of the possibility to experimentally detect and characterize a lead halide layer formed at the internal interface during degradation of a hybrid perovskite photovoltaic film using in situ neutron reflectometry, is presented. From a comparison of the calculated specular reflection curves, the relationships between the parameters of the system components are identified, at which, despite the generally weak changes in the curves, still it is possible to trace the evolution of this layer.
