Theoretical Insight into High-Efficiency Triple-Junction Tandem Solar Cells via the Band Engineering of Antimony Chalcogenides

Yu Cao et al.

Summary: This study designed and optimized triple-junction antimony chalcogenides-based solar cells with a high theoretical efficiency. By maintaining a low selenium content in the mid-cell, the external quantum efficiency of the solar cells was increased. Additionally, regulating the bandgap gradient through selenium content gradient in single-junction solar cells improved the conversion efficiency.

Solution-Processed Compact Sb2S3 Thin Films by a Facile One-Step Deposition Method for Efficient Solar Cells

Liangxin Zhu et al.

Summary: A facile one-step deposition method is reported for preparing Sb2S3 nanoparticle films with preferential orientation for efficient solar cells. The effects of precursor solution concentration and [S]/[Sb] molar ratio on film formation and device performance were investigated to achieve a considerable power conversion efficiency of 5.74% under AM 1.5G illumination. This solution-processing method provides a promising approach for preparing high-quality Sb2S3 films for efficient solar cells and other optoelectronics.
