Resumen

The Solar Cell Laboratory from the Instituto Tecnológico y de Energías Renovables (ITER), with the support of the La Laguna University (ULL), has been working on the development of low temperature encapsulation methods, suitable to protect Perovskite Solar Cells (PSCs). This document summarizes the work carried out to evaluate the performance of perovskite solar cells, based on MAPbI3 absorbers, which were encapsulated at low temperature and then the International Summit on Organic photovoltaic Stability (ISOS-T) protocols were applied. Three types of polymer materials were studied, those composed of Ethyl Vinyl Acetate (EVA), those composed of Poly(methyl methacrylate) (PMMA), and those composed of Polyvinylidene fluoride (PVDF) combined with EVA. The degradation of the samples was characterized by imaging microscope, optical ellipsometry and the electrical performance was simulated by the SCAPS-1D software. The results indicate EVA encapsulated samples remained stable after the 200 thermal cycles, keeping the samples a 15.06% PCE compared to the 15.96% PCE of the pristine ones, with a reduction of 5% of total efficiency, meanwhile the PMMA and EVA-PVDF samples lost 59% and 35% PCE respectively.
