The influence of the “biography” of the PbSe films prepared by vacuum evaporation (VE) and chemical deposition (selenosulphate based procedure – CAD – and selenourea based procedure – COD) on their structure, phase composition, resistivity, and photoconductivity is studied. The considered processes perturbing the film–air system are ageing effects and different kinds of thermal treatments. It is evidenced that the number and the types of the active adsorption sites are the factors which differentiate between an “as‐grown” film and a film with a certain history.
