A novel and simple synthesis of the absorber layer is indispensable in order to reduce the cost and processing of quantum solar cells. In this work, we developed novel Cu2CoSnS4-carbon quantum dot (
CQD) nano-composite as an absorbing material for solar cell applications.
CQD nano-composites were prepared by direct pyrolysis of CCTS precursors and citric acid. The proportions of citric acid precursor to CCTS were varied from 0.1 to 0.7. The properties of the synthesized nano-composite were studied using a UV-Vis spectrophotometer in the wavelength range of 300-900 nm.
CQD has a property of dynamic photoluminescence that depends on the excitation wavelength. The results of the X-ray diffraction revealed that the
CQD nano-composites were predominantly polycrystalline in nature. The formation of
CQD was confirmed by a high-resolution transmission electron microscope (HRTEM), which exhibits the size ~3 nm. The thin films of
CQD nano-composites were deposited on glass/ITO substrates by spray pyrolysis technique at 170 °C. Current-voltage (I-V) measurements carried out in dark and light conditions revealed
CQD thin films with good photo-response. The purpose of the present study is to develop
CQD nano-composite p-type absorber layer suitable for thin film solar cells.
