A NEW METHOD OF METALLIZATION FOP SILICON SOLAR CELLS SECOND QUARTERLY REPORT

摘要

THE SECOND QUARTER, OF THIS PROGRAM IS CONCERNED WITH THE DETERMINATION OF THE FIRING CYCLE IN A HORIZONTAL TUBE FURNACE FOR MOO3: SN INK COMPOSITION APPLIED BT SILK SCREENING PROCESS ON P ON IF STRUCTURED SOLAR CELLS,nIN COMPARISON WITH THE STRIP HEATER USED IN TUZ FIRST QUARTER TO DETERMINE THE REACTION MECHANISM, THE REDUC¬TION OF MOO3 IN THE TUBE FURNACE PROGRESSES AT A MUCH FASTER RATE AND THE SN:UO ALLOT FORMS AT A MUCH LOWER TEMPERATURE, THE DEVICE CHARACTERISTICS DETERMINED BT THE V-I CURVE SHOWED A HIGH RESISTANCE (APPROX, 10 OHMS) AT PEAK TEMPERATURES BETWEEN 6Q0°C AND 800°C, THE HIGH SERIES RESISTANCE CAN BE ATTRIBUTED TO THE LACK OF FORMATION OF MOSI2 WITHIN THE USED TEHPSRA-TURE RANGE AS POINTED OUT IN REFERENCES TO THEORETICAL AND EXPERIMENTAL WORK CONCERNED WITH THE FORMATION OF METAL SUICIDES,
