摘要：

Cu2SnS3 (CTS) is an emerging semiconducting absorber layer material for solar cells having energy band gap of around 1 eV. In this work CTS powders has been synthesized from metal salts using different sulphur sources. It is found that thiourea yielded pure CTS. The composition of the prepared material has been confirmed by X-ray diffraction (XRD), which shows the CTS powder to be nanocrystalline with triclinic phase. Also the time of the completion of reaction has been optimized by studying the XRD pattern of the product at different time interval of reaction. The diffuse reflectance spectrum of CTS depicts the energy band gap for the sample to be 1.1 eV. The electrical measurement of the pellet of the CTS powders proves the material to have p-type conduction with thermoelectric coefficient of 95 mu V/K as determined from hot-probe method. The electrical conductivity of the pellet is 10(-2) mho/cm.
