dc.description.abstractTHE USE OF SOLAR RADIATION TO GENERATE ELECTRICITY IS A PROMISING SOLUTION TO THE GLOBAL ENERGY CRISIS, DUE TO ITS LOW CARBON FOOTPRINT AND GLOBAL AVAILABILITY. IN THIS SENSE, THIN FILM SOLAR CELLS ARE AN INTERESTING ALTERNATIVE BECAUSE OF ITS GOOD CONVERSION EFFICIENCIES AND THE SMALL AMOUNT OF MATERIAL NEEDED FOR THEIR MANUFACTURE [1]. ON THE OTHER HAND, NANOSTRUCTURED METAL SULFIDES HAVE BEEN EXTENSIVELY STUDIED DUE TO THEIR EXCELLENT PROPERTIES AND PROMISING APPLICATIONS IN ELECTRONIC AND OPTOELECTRONIC DEVICES, SUCH AS SOLAR CELLS, LIGHT-EMITTING DIODES, AND NON-VOLATILE MEMORIES [2]. IN THIS SENSE, CDS IS A COMMONLY USED OPTICAL WINDOW MATERIAL IN THIN FILM SOLAR CELLS, DUE TO ITS HIGH OPTICAL TRANSPARENCY, WIDE BANDGAP ENERGY (2.42 EV) AND N-TYPE CONDUCTIVITY. TO USE AS AN ABSORBER LAYER, PBS HAS INTERESTING FEATURES LIKE DIRECT BANDGAP ENERGY (0.41 EV AT 300 K) P TYPE CONDUCTIVITY, AND LARGE EXCITON RADIUS (18 NM) WHICH PROVIDES STRONG QUANTUM CONFINEMENT OF ELECTRONS AND HOLES, THUS INCREASING THE ABSORPTION FOR SOLAR RADIATION IN THE NEAR INFRARED REGION [3]. IN THIS WAY, CDS/PBS THIN FILM SOLAR CELLS WITH LAYERS DEPOSITED BY MEANS OF CHEMICAL BATH DEPOSITION HAVE BEEN INVESTIGATED BY SEVERAL AUTHORS, WHERE THEY HAVE OBTAINED GOOD EFFICIENCIES BETWEEN 0.44 % AND 4.85 % [3-6]. CURRENTLY, CHEMICAL BATH DEPOSITION (CBD) IS A LOW-COST, SCALABLE AND EASY TECHNIQUE TO SYNTHESIZE SEMICONDUCTOR THIN-FILMS [3-7]. NOW, IN BOTH SEMICONDUCTORS IT IS POSSIBLE TO MODIFY THEIR PROPERTIES BY INTRODUCING METALLIC DOPANTS INTO THEIR STRUCTURE, LIKE ITS BANDGAP VALUE AND ELECTRICAL CONDUCTIVITY. IN THIS SENSE, DOPING WITH AL HAS BEEN REPORTED FOR CHEMICALLY-DEPOSITED CDS AND PBS FILMS SHOWING IN BOTH CASES AN IMPROVEMENT IN THEIR ELECTRICAL CONDUCTIVITY AND A MODIFICATION OF ITS BANDGAP ENERGY AND CRYSTALLITE SIZE [6-9]. MOREOVER, DIFFERENT OPTOELECTRONIC DEVICES HAVE BEEN REPORTED RECENTLY USING CBD AL-DOPED CDS THIN FILMS [10-13].
