SOLAR CELL RESEARCH HAS DEVELOPED INTENSELY OVER THE LAST FEW YEARS. THE DISCOVERY OF EFFICIENT CELLS OF ORGANIC-INORGANIC HYBRID MATERIALS WITH PEROVSKITA M STRUCTURE [ORG] X3, BEING M PB OR SN, HAS ORGANISED AN ORGANIC GROUP LIKE METHYLAMIUM, AND X A HALOGENE, HAS REVIVED THE INTEREST FOR THIRD GENERATION CELLS, AND PROMISES TO ACHIEVE HIGH EFFICIENCIES WITH LOW TEMPERATURE PREPARATION ROUTES. ALTHOUGH THESE SOLAR CELLS HAVE QUICKLY ACHIEVED CONVERSION EFFICIENCIES OF 15 %, THERE IS AMPLE SCOPE TO BRING THIS PERFORMANCE CLOSE TO THE THEORETICAL LIMIT, BEYOND 20 %, AND ACHIEVE A LOW-COST MANUFACTURING TECHNOLOGY ON A LARGE SCALE AND HIGH EFFICIENCY. THE PROPERTIES AND MECHANISMS OF THESE MATERIALS APPEAR TO BE DISTINCT FROM THE RELATED DEVICES AND ARE STILL UNKNOWN. _x000D_ the PROJECT PROPOSES THE DEVELOPMENT OF Perovskita CELLS FOR THE INNOVATION OF MATERIAL AND DISPOSITIVES AND THE COMPRENSION OF FUNDAMENTAL PHISIC PROCESSES CONTROLING PHOTOVOLTAIC OPERATION. NEW LIGHT ABSORBING MATERIALS FROM PEROVSKITA M[ORG]X3 WILL BE DEVELOPED TO IMPROVE THE STABILITY AND PERFORMANCE OF THE DEVICE, AND TO ELIMINATE HARMFUL COMPONENTS SUCH AS PB. A SYSTEMATIC INVESTIGATION OF MATERIALS AND CONTACT MORPHOLOGIES USING NANOSTRUCTURES WILL BE CARRIED OUT. TYPE N CONTACTS WILL BE BASED ON METAL OXIDES (TIO2, ZNO, SNO2) AND ORGANIC LAYERS (FULLERENE, GRAPHENE, PCBM...), AND P-TYPE CONTACTS, BASED ON ORGANIC AND INORGANIC MATERIALS (SPIRO-OMETAD, CONDUCTIVE POLYMERS, NIO, MOO3, CUSCN). THE SYSTEMATIC CHARACTERISATION OF THE STRUCTURAL, OPTICAL AND ELECTRICAL PROPERTIES OF THE MATERIALS AND DEVICES WILL BE PERFORMED. MODELS AND EXPERIMENTS WILL BE ESTABLISHED TO DETERMINE THE PHYSICAL MECHANISMS OF THE PHOTOVOLTAIC OPERATION THAT ALLOWS DETAILED UNDERSTANDING OF THE OPERATION OF THE DEVICE. SPECIFIC TECHNIQUES OF CHARACTERISATION OF PEROVSKITA PHOTOVOLTAIC CELLS WILL BE MADE THAT ALLOW TO RECOGNISE THE MOST EFFECTIVE COMBINATIONS OF MATERIALS. These STUDIES will lead to high-income, low cost and great stABILITY, and will also be a part-sided point for a new FAMILY OF OPTOELECTRONIC FUNCIONAL MATERIALS._x000D_ THE THREE GROUPS IN THE COORDINATED PROJECT WITH THE CAPACITY OF THE PREPARATION OF NEED MATERIALS, the FORMATION OF HIGH EFICIENCE PROPOSITIVES, the INVESTIGATION OF FUNDAMENTAL PROPIEDS OF MATERIAL AND DISPOSITIVES, AND THE REALISATION OF NEW TECHNICAL CARACTERISATIONS ADAPTED TO FOTOVOLTAIC PROPOSITIVES
