RT journal article T1 Chemical composition determination of impurities and effect on the toxicity degree of solar panel components A1 Vezhenkova, Irina A1 Semenova, Margarita A1 Kovalevskaya, Alla A1 Gryaznov, Artem A1 Rodríguez Barroso, María del Rocío A1 Jiménez Castañeda, Rafael A2 Ingeniería Eléctrica A2 Tecnologías del Medio Ambiente AB By 2050, according to the conclusion of the European Commission, the amount of solar panels waste will reach 78 million tons. 85% of all solar panels produced today belong to polycrystalline solar panels. The subject of this paper is the polymer components of polycrystalline solar panels EVA (ethyl vinyl acetate) and Tedlar® (polyvinyl fluoride). The paper reflects studies to determine the chemical composition of impurities of the solar panel components, and the degree of impurities influence on the toxicity of polymer components.
