| Abstract Scope |
The search for transparent electrodes with a perovskite structure has gained significant attention due to the increasing demand for perovskite-structured solar cells to enhance its performance and high photon conversion efficiencies. Stannate-based compounds have emerged as a promising alternative due to their significant mobility, which is derived from the s-orbitals in their conduction band minimum. This study investigated the electrical and optical properties of La-doped SrSnO3 bulk and thin films. The results indicated that La-doped SrSnO3 has improved electrical conductivity and optical transparency, with reduced tilting values leading to its physical properties. X-ray photoelectron spectroscopy and X-ray absorption spectroscopy also revealed the presence of oxygen vacancies contributing to the total electron concentration. These findings suggest that La-doped SrSnO3 has the potential to be used as a transparent conductive oxide material in solar cell applications, providing a viable alternative to traditional TCO materials. |
