ORGANIC-INORGANIC MATERIALS COMPOSED OF LEAD, HALOGENE AND AN ORGANIC CATION FORMING PEROVSKITA STRUCTURE HAVE LED TO A REAL REVOLUTION IN THE FIELD OF PHOTOVOLTAIC AND OTHER RELATED OPTOELECTRONIC APPLICATIONS. WITH THESE MATERIALS SOLAR CELLS HAVE BEEN FORMED WITH CHEMICAL ROUTES OF LOW COST OF REMARKABLE ELECTRICITY-TO-LIGHT CONVERSION YIELDS, GREATER THAN 22 %, AND THEREFORE PROMISE TO BECOME A VIABLE OPTION TO ACHIEVE LOW-COST SOLAR ENERGY, WHICH CONTRIBUTE A SIGNIFICANT CONTRIBUTION TO THE RENEWABLE ENERGIES OF THE FUTURE. HOWEVER, THE EXPERIENCE OF THE LAST FEW YEARS INDICATES THAT SYSTEMATIC STUDIES MUST BE CARRIED OUT TO SOLVE SOME CRUCIAL PROBLEMS. FIRST, IT IS NECESSARY TO ESTABLISH A COMPLETE CONTROL OF THE RELATIONSHIP BETWEEN COMPOSITION, METHODS OF PREPARATION, MORPHOLOGY, AND OPERATION. THE SYSTEMIC KNOWLEDGE OF THESE ELEMENTS WILL ALLOW TO HAVE ROBUST METHODS OF PREPARATION IN SCIENTIFIC LABORATORIES, PREPARE THE WAY FOR INDUSTRIAL METHODS OF LARGE SURFACE, IMPROVE STABILITY, ELIMINATE THE TOXICITY OF COMPONENTS, AND DESIGN OTHER APPLICATIONS IN RELATED FIELDS SUCH AS OPTOLECTRONICA, PHOTOELECTROQUIMICA, SENSORS, ETC. IN THIS PROJECT WE HAVE DEVELOPED A SOLID STRATEGY BASED ON FIVE MAIN AXES TO CONSOLIDATE THE PROGRESS OF PEROVSKITA SOLAR CELLS. IN THE FIRST PLACE WE SET OBJECTIVES OF SYSTEMATIC STUDIES OF METHODS OF PREPARATION AND COMPOSITIONAL VARIATIONS OF PEROVSKITES, WHICH HAVE NOT YET BEEN ESTABLISHED CONSISTENTLY PREVIOUSLY. AT THE SAME TIME WE ADDRESS TWO OBJECTIVES THAT ALLOW US TO DEEPEN THE UNDERSTANDING OF THE FUNCTIONING OF THESE MATERIALS: TO STUDY THE RELATIONSHIP BETWEEN MORPHOLOGY (CRYSTALINITY, CONTACTS, ETC.) AND FUNCTION, AND ON THE OTHER HAND TO DEEPEN THE UNDERSTANDING OF PROPERTIES, EMPLOYING A COMBINATION OF NUMERICAL SIMULATION METHODS AND EXPERIMENTAL TECHNIQUES OF CHARACTERISATION. FINALLY, THE INNOVATION OF MATERIALS AND PROPERTIES IS ADDRESSED BY CONDUCTING A STUDY OF DIFFERENT TYPES OF APPLICATIONS RELATED TO, BUT DIFFERENT, PHOTOVOLTAIC, IN ORDER TO OBTAIN HIGHLY ORIGINAL RESULTS IN NEW FUNCTIONAL MATERIALS.
