The group of Prof. Palomares works on the design, 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 (photo) electrocatalyzers. The understanding of the device behavior is completed by characterization of the charge transfer reactions using advanced photo-induced transient and steady-state spectroscopy under operating conditions. The group has described the preparation of organic, perovskite and dye sensitized solar cells with special emphasis in the application and study of the selective contacts. In this sense, the use of self-assembled selective contacts in perovskite solar cells has allowed the increase in stability and efficiency through a novel approach combining increased charge collection and the surface passivation of the defects in the perovskite.

The group has reported their results as well in the application of sunlight as an energy source and as an initiator of catalytic reactions in the conversion of CO2 and H2 generation.
