    Description

    Exploration of new and more sustainable semiconductor nanomaterials is a major research thrustto find a material which can provide improved performance in terms of energy efficiency andminiaturization. In this work, novel multinary copper-based chalcogenides nanocrystalsincluding tellurides were synthesized in the solution phase and their electrochemical propertieswith respect to structure were investigated. These nanocrystals are then deposited on the Siliconwafers using dip coating method and then drying it under the fume hood at 25 °C. CyclicVoltammetry (CV) method is used to measure the charge storage capacity of our material withthe help of Versa Stat-4. A quasi-solid-state device was fabricated by sandwiching twoelectrodes, working electrode obtained by using dip coated nanomaterial and reference electrodeis obtained by using the mixture of potassium chloride (KCl) and silver chloride (AgCl),separated by an ion transporting layer in the presences of Potassium Hydroxide (KOH) andSodium Hydroxide (NaOH) as electrolytes. Electrochemical measurements such as specificcapacitance and CV curves show promising results for these materials to be used in batteries andphotovoltaic devices.
