“…After coating the p-type a-Si: H layer, the front surface coatings were completed with the deposition of ITO films at different temperatures. Finally, finger and busbar patterns were printed on the front surface of the HJT solar cells using Ag paste via the screen print method (ASM Assembly Systems, Munich, Germany), and the solar cell was completed by firing it at 200 °C for 10 min [ 28 , 29 ]. Figure 1 a provides a schematic representation and eV diagram [ 30 ] of the HJT solar cell.…”

This study examined the impact of temperature optimization on indium tin oxide (ITO) films in monolithic HJT/perovskite tandem solar cells. ITO films were deposited using magnetron sputtering at temperatures ranging from room temperature (25 °C) to 250 °C. The sputtering target was ITO, with a mass ratio of In2O3 to SnO2 of 90% to 10%. The effects of temperature on the ITO film were analyzed using X-ray diffraction (XRD), spectroscopic ellipsometry, and sheet resistance measurements. Results showed that all ITO films exhibited a polycrystalline morphology, with diffraction peaks corresponding to planes (211), (222), (400), (440), and (622), indicating a cubic bixbyite crystal structure. The light transmittance exceeded 80%, and the sheet resistance was 75.1 Ω/sq for ITO deposited at 200 °C. The optical bandgap of deposited ITO films ranged between 3.90 eV and 3.93 eV. Structural and morphological characterization of the perovskite solar cell was performed using XRD and FE-SEM. Tandem solar cell performance was evaluated by analyzing current density-voltage characteristics under simulated sunlight. By optimizing the ITO deposition temperature, the tandem cell achieved a power conversion efficiency (PCE) of 16.74%, resulting in enhanced tandem cell efficiency.

“…Of these techniques, magnetron sputtering is widely employed due to its low substrate temperatures and high accumulation rates, as well as its suitability for industrial applications and its ability to ensure the excellent optoelectronic performance of the film [4,7]. The most widely utilized TCO films include indium tin oxide (ITO) [20][21][22], indium zinc oxide (IZO) [23], aluminum zinc oxide (AZO) [24], fluorine tin oxide (FTO) [25], gallium zinc oxide (GZO) [26], molybdenum zinc oxide MZO [27], and tungsten oxide (WO 3 ) [28,29]. The III-group element Indium is the most effective dopant material among these TCO films owing to its ease of processing, resistance to oxidation, and low reactivity [30].…”

In this study, we investigated the potential of multilayer TCO structures, specifically those made up of Indium Tin Oxide (ITO) and Indium Zinc Oxide (IZO), for crystalline silicon heterojunction solar cells (SHJ). We used the radiofrequency (RF) magnetron sputtering method to deposit various thin-film structures under various deposition temperatures and evaluated their electrical, optical, and morphological properties. The objective was to obtain films with lower sheet resistances and higher transmittances than those of single-layer thin films. Our results show that the ITO/IZO/ITO/IZO/ITO multilayer film structure deposited at 200 °C achieves the best sheet resistance of 18.5 Ohm/sq and a high optical transmittance of over 90% at a 550 nm wavelength. This indicates that multilayer TCO structures have the potential to be more optically and electrically efficient, and that they can improve the performance of optoelectronic devices. Finally, a power conversion efficiency of 17.46% was obtained for a silicon heterojunction (SHJ) solar cell fabricated using an ITO/IZO/ITO/IZO/ITO multilayer film structure deposited at 200 °C as a front TCO. Our study provides valuable insights into the field of TCOs and offers a promising avenue for future research.
