NOVELTY - Glass powder is roughened, cleaned, subjected to powder sedimentation, upper layer is removed and remaining glass powder suspension is washed and dried, to obtain roughened glass powder. The glass powder is then activated using sensitizing liquid, and subjected to solid-liquid separation. The separated solid is washed and dried, to obtain sensitized glass powder. The sensitized glass powder is introduced into silver nitrate solution, reducing agent is added, stirred, separated, and obtained silver-coated glass powder suspension is washed and dried, to obtain silver-coated glass powder.    USE - Preparation of silver-coated glass powder used for electrode of solar cell.    ADVANTAGE - The method provides silver-coated glass powder having excellent conductivity and reduced contact resistance, by a simple process. The conversion efficiency of solar cell is improved by using the silver-coated glass powder.    DETAILED DESCRIPTION - The glass powder is roughened, cleaned ultrasonically, subjected to powder sedimentation, upper layer is removed and the remaining glass powder suspension is washed with deionized water for 3-5 times and dried at room temperature, to obtain roughened glass powder. The roughening is performed using roughening solution containing deionized water, sodium fluoride and hydrochloric acid. The roughened glass powder is activated by ultrasonic cleaning using sensitizing liquid, and subjected to solid-liquid separation. The separated solid is washed 3-5 times with deionized water, and dried at room temperature, to obtain sensitized glass powder. The sensitizing liquid contains sodium chloride solution, aqueous tin chloride solution and hydrochloric acid solution. The sensitized glass powder is introduced into silver nitrate solution, reducing agent is added, stirred at 40-60 degrees C for 3 minutes and separated, to obtain silver-coated glass powder suspension. The obtained suspension is washed thrice with water and alcohol and dried at room temperature, to obtain silver-coated glass powder.
