Descripción del proyecto MATER-ONE PROPOSES TO DEVELOP A NEW GENERATION OF CHALCO-HALIDES SEMICONDUCTORS WITH LOW DIMENSIONALITY, THAT ARE SPECIALLY WELL SUITED FOR PHOTOVOLTAIC (PV) APPLICATIONS THAT REQUIRE MATERIALS WITH LOW PROCESSING TEMPERATURE, HIGH STABILITY AND EXCELLENT CONVERSION EFFICIENCY, VERY RECENTLY, Q1-D MATERIALS BASED ON SB2(S,SE)3 HAVE ATTRACTED A LOT OF ATTENTION FROM THE THIN FILM PV COMMUNITY, DUE TO THEIR UNIQUE PROPERTIES, THIS LOW DIMENSIONAL SYSTEM EXHIBITS EXCELLENT PROPERTIES AS SUN-LIGHT ABSORBER, SUCH AS VERY GOOD TRANSPORT CHARGE AND ELECTRICAL PROPERTIES ALONG THE C-AXIS, GOOD STABILITY, EASY N- AND P-TYPE DOPING, AND DEMONSTRATED CONVERSION EFFICIENCIES ABOVE 10%, ALL THIS TOGETHER WITH A LOW TEMPERATURE PROCESSING (<350 ºC), THAT IS UNIQUE FOR A CHALCOGENIDE SYSTEM FOR PV DEVICES, OPENING VERY RELEVANT PERSPECTIVES FOR APPLICATIONS WHERE CONVENTIONAL THIN FILM MATERIALS WITH MUCH HIGHER SYNTHESIS AND CRYSTALLIZATION TEMPERATURES ARE NOT WELL ADAPTED, IN THIS FRAME, THE POLYTECHNIC UNIVERSITY OF CATALONIA (UPC) SUB-PROJECT AIMS TO CONTRIBUTE WITH THE SYNTHESIS AND CHARACTERIZATION OF A NEW CLASS OF LOW DIMENSIONAL MATERIALS BASED ON MIXED CHALCO-HALIDES BY CO-EVAPORATION TECHNIQUE, INCLUDING COMPOUNDS WITH THE GENERIC FORMULA (GE,SN,SB,BI)X(S,SE)Y(BR,I)Z FOR ADVANCED PV APPLICATIONS, IN STRONG SYNERGY WITH THE OTHER INSTITUTIONS INVOLVED IN MATER-ONE, UPC TEAM WILL WORK IN THE SYNTHESIS OF NEW MIXED CHALCO-HALIDES USING CONFOCAL CO-EVAPORATION TECHNIQUE FOR THE DEPOSITION OF HIGHLY CRYSTALLINE CHALCOGENIDE COMPOUNDS, FOLLOWED BY AN INNOVATIVE HIGH PRESSURE ANNEALING TO INTRODUCE THE DESIRED HALIDES, THIS WAY, DIFFERENT COMPOUNDS WILL BE SYNTHESIZED AND FULLY CHARACTERIZED TO IDENTIFY THE POTENTIAL SYSTEMS WITH LOW DIMENSIONALITY AND PROPERTIES SUITED FOR ADVANCED PV APPLICATIONS, THE MOST INTERESTING CANDIDATES WILL BE TESTED IN SOLAR CELL DEVICES, BY DEVELOPING HIGHLY SELECTIVE ELECTRON AND HOLE TRANSPORT LAYERS, IN THIS REGARD, OXIDES SUCH AS V2O5, MOOX OR TIO2 WILL BE EXPLORED AS ASYMMETRIC SELECTIVE CONTACTS, AS WELL AS SOME POSSIBLE ORGANIC COMPOUNDS INCLUDING SEVERAL AMINOACIDES AND CONJUGATED POLYELECTROLYTES, WITH THIS INNOVATIVE LOW DIMENSIONAL ABSORBERS AND DEVICES ARCHITECTURE, A SOLAR CELL WITH A CONVERSION EFFICIENCY ABOVE 18% IS TARGETED, WITH ALL THE PROCESSING TEMPERATURES BELOW 350 ºC FOR THE FIRST TIME FOR A FULLY INORGANIC PV ABSORBER, THE BEST CANDIDATES WILL BE THEN TRANSFERRED TOWARDS A TANDEM SOLAR CELL, USING C-SI AS BOTTOM DEVICE, AND LOW TEMPERATURE PROCESSING MIXED CHALCO-HALIDE COMPOUND WITH A BANDGAP BETWEEN 1,6-1,8 EV AS TOP DEVICE, THE LOW PROCESSING TEMPERATURE OF THESE NOVEL COMPOUNDS WILL ALLOWS TO KEEP UNALTERED THE PROPERTIES AND EFFICIENCY OF THE BOTTOM C-SI SOLAR CELL, PERMITTING TO TARGET A 28% EFFICIENCY DEVICE BY ADJUSTING THE DIFFERENT CONTACTING LAYERS OF THE TANDEM DEVICE, AT THE END OF THE PROJECT, THE UPC SUBPROJECT WILL CONTRIBUTE TO IDENTIFY, SYNTHESIZE AND REALIZE A FIRST PROOF OF CONCEPT OF A SOLAR CELL DEVICE BASED ON LOW TEMPERATURE PROCESSING MIXED INORGANIC CHALO-HALIDE COMPOUNDS, FULLY COMPATIBLE WITH ADVANCED PV APPLICATIONS SUCH AS TANDEM SOLAR CELLS, ENERGIA SOLAR\DISPOSITIVOS FOTOVOLTAICOS DE CAPA FINA\CALCOGENUROS\HALUROS\MATERIALES DE BAJA DIMENSION\CELDAS SOLARES TANDEM\AGROFOTOVOLTAICOS\DEPOSITO EN FASE VAPOR\DEPOSITO POR RUTAS QUIMICAS\CARACTERIZACION AVANZADA
