Abstract
This study explores the potential of Ge-enhanced Cu2SnS3 (CTS) thin-films as photoelectrode materials for water splitting grown through a simple sulfurization process. The addition of Ge to CTS enabled tuning the bandgap and improved the photocurrent density. Films sulfurized at 520 °C exhibit enhanced grain size and reduced grain boundaries, which contribute to increased carrier transport efficiency. By optimizing Ge content and sulfurization conditions, the Cu2(Sn1−x,Gex)S3 films demonstrate promising capabilities for efficient green hydrogen production. This work lays the groundwork for developing advanced photoelectrodes and highlights the need for further refinement to maximize performance for practical applications.
本研究探讨了通过简单的硫化工艺生长的 Ge 增强 Cu2SnS3（CTS）薄膜作为光电极材料用于水分离的潜力。在 CTS 中添加 Ge 能够调整带隙并提高光电流密度。在 520 °C 下硫化的薄膜显示出更大的晶粒尺寸和更小的晶界，这有助于提高载流子传输效率。通过优化 Ge 含量和硫化条件，Cu2(Sn1-x,Gex)S3 薄膜展现出了高效绿色制氢的潜力。这项工作为开发先进的光电电极奠定了基础，并强调了进一步改进的必要性，以最大限度地提高实际应用的性能。
