Summary
The group of Prof. Palomares works on the synthesis and characterization of molecules and materials with optical and electrical properties. Through these materials, the group manufactures electronic devices, including solar cells, light emitting diodes and sensors. Additionally, all interfacial load transfer reactions are characterized by the use of advanced photo-induced transient spectroscopy under operating conditions. The group has described the preparation of organic solar cells with an efficiency greater than 10% and solar cells of perovskite with an efficiency of 19%. These efficiency values are among the best published in the scientific literature and have been possible thanks to the study and minimization of the losses of recombination of loads. The group aspires to understand the relationship between the molecular structure and the function of the devices.
