Abstract: The light dependent resistor (LDR) are prepared using bulk CdS material and using conventional thick film technique. But bulk CdS and this conventional thick film technique gives lower inter-electrode spacing resulting poor response. In the present work, the CdS nanostructure was synthesized using hydrothermal reaction technique and with the help of screen printing technique, the CdS pattern having lower inter-electrode spacing resulting larger length of the CdS was prepared. As the inter electrode spacing increases the photocurrent also increases resulting enhancement of the sensor response. The work reported in the present paper provides the photo-sensor having higher sensitivity.
