Cel THE AIM OF THIS RESEARCH IS THE ACHIVEMENT OF HIGH EFFICIENCY (10%) THIN FILM SOLAR CELLS IN WHICH BOTH THE CUINSE2 ABSORBER LAYER AND THE CDS WINDOW LAYER ARE PREPARED BY A SCALABLE TECHNIQUE LIKE R.F. SPUTTERING. AS SUBSTRATES WE USE ONE INCH SQUARE GLASSES COVERED BY 4 MICROMETRES THICK AL FILM WHICH IS OBTAINED CRYSTALLINE WITH AN AVERAGE GRAIN SIZE ON THE ORDER OF 100 MICROMETRES BY USING AN ORIGINAL METHOD DEVELOPED IN OUR LABORATORY. THE AL FILM IS COVERED BY A 1000 ANGSTROEM THICK MO LAYER WHICH CAN BE DEPOSITED BOTH BY SPUTTERING OR ELECTRON GUN EVAPORATION. THE FIRST DEVICES WERE PREPARED BY DEPOSITING CUINSE2 FILMS BY SPUTTERING AND CDS FILMS BY FLASH-EVAPORATION. AFTER DEVELOPING A NEW METHOD WHICH ALLOWS US TO OBTAIN BY SPUTTERING AT 200 CELSIUS DEGREES SUBSTRATE TEMPERATURE PURE CDS FILMS WITH A RESISTIVITY OF 1CM AND IN-DOPED CDS FILMS WITH A RESISTIVITY OF 10 TO THE POWER MINUS 3 CM, THE COMPLETE DEVICE, EXCLUDING THE AL AND MO LAYERS WHICH ARE DEPOSITED BY ELECTRON GUN EVAPORATION, IS PREPARED BY SPUTTERING. SO FAR, ALL SPUTTERED CUINSE2/CDS THIN FILM SOLAR CELLS HAVE SHOWN A MAXIMUM EFFICIENCY OF 5%. IN ORDER TO INCREASE THE EFFICIENCY, THE CUINSE2 LAYER HAS TO BE IMPROVED. SINCE EVAPORATED CUINSE2/CDS THIN FILM SOLAR CELLS HAVE SHOWN EFFICIENCY HIGHER THAN 10% ONLY WHEN THE CUINSE2 FILM IS PREPARED BY DEPOSITING AN IN-RICH LAYER ON TOP OF AN ALMOST STOICHIOMETRIC LAYER, OUR FUTURE WORK WILL BE DEDICATED TO THE PREPARATION BY SPUTTERING OF A DOUBLE LAYER CUINSE2 FILM BY USING TWO TARGETS WITH DIFFERENT STOICHIOMETRIES.
