Abstract [eng] Architectural textiles (AT) are becoming increasingly important in everyday life and have attracted increased attention from the scientific community in the last decade. This interdisciplinary area of interest ranges from materials science to photovoltaic cells. The concept of textile-integrated flexible photovoltaic systems (TE-EPV) is one of the most promising forms of technology [1]. Semiconducting oxides have been used in photovoltaic (PV) technology for many years. The versatility of their properties and the simplicity of their production methods give oxides a unique place in relation to the new generation of PV. Metal oxides are stable at ambient temperature and are generally harmless to living organisms. Many metal oxides are n-type semiconductors. Silver(I) oxide belongs to p-type oxides and can form oxide p-n heterojunctions in solar cells. The optical band gap for Ag2O ranges from 1.2 eV [2] to 3.4 eV [3] depending on the stoichiometry, structure and physical properties that result from the deposition method. Throughout the exploitation AT undergoes mechanical stress, thermal effects, chemical corrosion, etc., causing aging and functional loss of materials. In this study, silver oxide films were synthesised by SILAR method on a 0.53 mm thick AT (SATTLER– PROTEX Austria). It was made from the polyethylene terephthalate (PET) fabric with double-sided polyvinylchloride (PVC) and lacquer coatings. Filler pigment is not specified, but from XRD analysis it was determined that the dominant inorganic filler was CaCO3 and TiO2. The main objective of this study is to elaborate the effect of thermal aging on structural and optical properties of obtained Ag-O/PET/PVC composites. Thermal aging was carried out by keeping samples in air at a temperature of 70°C and atmospheric pressure for 336 hours. [...].
