“…Raman spectroscopy is used to examine the vibrational modes of the film surface. As reported in the previous paper [29], CIS thin film has two structures CH-ordering and CAordering. Figure 4 clearly depicted that the peak shifted with the increase in the solvent volumes.…”

CuInS 2 (CIS) thin films have been synthesized onto the glass substrates for different solvent volumes (10, 30, 50 and 70 ml) by nebulizer spray technique. The effect of solvent volume on the structural, morphological, compositional, optical and electrical properties of CIS thin films has been investigated. X-ray diffraction patterns suggest that the obtained CIS films are polycrystalline with the tetragonal structure. The surface morphology of the prepared CIS films purely depends on the solvent volume. The elemental quantitative investigation and the stoichiometric ratio of the CIS thin films were verified from XPS and EDS. High absorbance with the optical band gap of 1.13 eV was obtained at the higher solvent volume. All the deposited CIS thin films exhibited p-type semiconducting behavior with the high electrical conductivity and carrier concentration. CIS thin films deposited onto the FTO substrate were used as a counter electrode (CE) in dye-sensitized solar cells. CIS CEs possessed high electrocatalytic behavior and fast electron charge transfer at the CE/electrolyte interface. The CIS CE prepared using 50 ml solvent volume generated high energy conversion efficiency of about 3.25 %.

“…It is shown that the ratio of Cu/(In + Zn) = 1.05, indicating a Cu-rich nature of absorber layer. Cu-rich condition is not favored in high temperature CIGS solar cells, as Cu x Se is formed by selenization process [43][44][45]. The presence of Cu x Se in absorber layer leads to diminishing the interface properties due to reduced photo carrier separation and decrease the open circuit voltage of the device.…”

Superstrate configuration CuInS2 (CIS) solar cells are fabricated using a spray pyrolysis method. We avoided selenization process, cyanide etching and CdS buffer layer, to keep the process ‘green’. CIS layers are formed by spray pyrolysis of an aqueous precursor ink containing metal chloride salts and thiourea at 350 °C. We investigated the effect of intentional Zn doping on structural, morphological and photovoltaic response of the fabricated CIS films by dissolving ZnCl2 in aqueous precursor solution. At a zinc doping level ranging between 0.25 and 1.00 mol%, Zn doping is found to improve the CIS crystal growth and surface morphology of CIS films. Compared with the performance of the non-doped CIS cell, the Zn-doped CIS solar cell displayed a remarkable efficiency enhancement of 58–97% and the maximum enhancement was obtained at a Zn content of 0.5 mol%. The device structure consists of and show promising PCE of 4.29 % without any anti-reflection coating. Over the course of 300 d under ambient condition, the fabricated device showed only 1% loss in efficiency.

“…Nebulizer spray method is simple, cost-effective and more advanced compared to conventional spray in preparing functional thin film coatings for different technical applications [20,21]. The precise control of droplets size has the ability to produce good adherent, pinhole-free nanostructured film which is more advantageous over conventional spray method [22].…”
