Abstract:

Thin films of Copper Nickel Selenide (CuNiSe) were synthesized on glass slides at room temperature using chemical bath deposition (CBD) method. The films were deposited from aqueous solution containing copper ion, nickel ion and potassium selenate (K2SeO4) at varying molar concentration of nickel ion with constant time and pH of the reaction bath. The optical absorption data reveals that films of CuNiSe absorbs strongly at the ultraviolet range of 300 nm and has above 60% transmittance in the visible–near infrared regions. The results revealed high average band gap energy that ranges between 2.8 eV to 3.5 eV. Average particle size films obtained ranges from 6.46 nm to 15.66 nm. The film is found suitable for window layer in p-n junction solar cell.
