Paper Abstract

p-Si/n-Cd1-xZnxS heterojunction are prepared by the electrodeposition method. Electrical and photoelectrical measurements have been carried out on heterojunctions having varying Cd1-xZnxS films composition 0 ≤ x ≤ 0.8 heart treatment temperature and time. It was found that annealing the heterojunctions at Ta=350 ÷ 380°C for τa=5÷8 min in air leads to an increase of photosensitivity in the 0.8÷1.34 μm spectral region. The detectivity, open circuit photovoltage and short circuit photocurrent density for heterojunctions p-Si/Cd0.3Zn0.7S were D*=(5÷8)•106cm•Hs1/2•W-1, Voc=0.6 V H Isc=5.6 mA/cm2, respectively.
