The Synthesis and the effect of Cu on optoelectronic qualities of β-In2S3 as a window layer for CIGS thin film solar cells

Abstract

In this paper, the vacuum thermal evaporation technique was used to investigate β-In2S3 doped with copper (Cu) as window layer thin film for solar cells. For various Cu doping levels, the characteristics of the thin films were studied utilizing structural, morphological, and optical characterization techniques, as well as dielectric testing. The research included X-ray diffraction (XRD), atomic force microscopy (AFM), scanning electron microscopy (SEM), Raman spectroscopy, and energy-dispersive X-ray spectroscopy (EDS), Infrared analysis (FTIR), XPS, Ellipsometry and UV-NIR spectroscopy. The measurements demonstrated that the real and imaginary isolation constants were over the wavelength range and successfully estimated the Urbach energy (Eu) and band gap energy. Moreover, employing the Wemple-Didomenico model helped uncover the Cauchy coefficients’ refractive index and the dispersion and oscillation energies. Therefore, the results presented in this paper show that the use of Cu-In2S3 for perovskite cells offers a high-efficiency alternative in the solar energy field.

Highly efficient photocatalytic degradation of organic polluants over Cu 2 AlSnS 4 (CATS) thin films: synthesis, chracterization and photocataysis Approch

“…compound have, nevertheless, been found to be deposited [15,16]. Based on previous [17][18][19][20] work and in continuation of our research interest, the present study is carried out to establish rstly an exclusive physical synthesis of new CATS quaternary compound using direct fusion process. After that exploiting the vacuum deposition technique for obtaining thin lms, that exhibits a noticeable change in physical properties as a result of the substrate temperature.…”
