A comprehensive numerical study of bilayer SnSe/SnS absorber based solar cells
Herein, we present the simulation (using the SCAPS-1D program), of a bilayer absorber solar cell. First, we numerically studied the bilayer model using our experimentally observed parameters and investigated the results. The results from the bilayer absorber (SnSe/SnS) numerical analysis were then compared with a single (SnS and SnSe) absorber modeling. The optimized device with a bilayer absorber exhibited the highest performance, with a photo conversion efficiency (PCE) of 22.35%. In comparison, the single SnS and SnSe absorbers achieved a PCE of 14.79% and 13.69%. Furthermore, we compared this numerical study with our previous study having the same configuration. Although there was a significant difference in performance between the simulated and experimental studies, the outcomes of the fabricated devices exhibited similar trends to the simulations. Finally, we attempted to determine the key parameters responsible for the reduced performance in the experimental study.
期刊介绍：
Current Applied Physics (Curr. Appl. Phys.) is a monthly published international journal covering all the fields of applied science investigating the physics of the advanced materials for future applications.
Other areas covered: Experimental and theoretical aspects of advanced materials and devices dealing with synthesis or structural chemistry, physical and electronic properties, photonics, engineering applications, and uniquely pertinent measurement or analytical techniques.
Current Applied Physics, published since 2001, covers physics, chemistry and materials science, including bio-materials, with their engineering aspects. It is a truly interdisciplinary journal opening a forum for scientists of all related fields, a unique point of the journal discriminating it from other worldwide and/or Pacific Rim applied physics journals.
Regular research papers, letters and review articles with contents meeting the scope of the journal will be considered for publication after peer review.
The Journal is owned by the Korean Physical Society.
