Description
There have been tremendous inputs into improving the efficiencies of nanostructure solar cells by extending their absorption wavelength to the near-infrared. This can potentially be achieved by using colloidal nanocrystal quantum dots as the light-harvesting material, as their optical band gap can be tuned to a desired range. Copper selenide is an interesting semiconductor with a bulk band gap of 1.39 eV. It has been shown to have good electrical conductivity properties. It is also used as a precursor for the preparation of CIDS solar cells. Herein, colloidal CuSe nanocrystals are synthesized using a modified solvothermal method and characterized with absorption and photoluminescence spectroscopy, XRD and HRTEM. The resultant nanocrystals are then used as the active material in a Schottky and hybrid solar cell.
