Design and simulation of three-junction all perovskite tandem solar cells: A path to enhanced photovoltaic performance
MATERIALS LETTERS(2024)
Abstract
Despite numerous publications on two-junction tandems using SCAPS-1D simulation, there is a gap in research regarding three-junction tandems. This paper explores the advantages of three junction all-perovskite tandem solar cells (3J-APTSC) where we introduce a new methodology utilizing two-step filtered spectrum and current matching techniques in SCAPS-1D to design realistic tandem solar cells. Crucial steps involve determining filtered spectrum and current matching points among sub-cells for tandem optimization. Our designed threeterminal tandem solar cell exhibits promising photovoltaic parameters, including VOC: 3.76 V, JSC: 10.70 mA/ cm2, FF: 69.00 %, and PCE: 26.24 %, achieved through optimized active layer thicknesses. This thorough examination of 3J-APTSC offers insights that could drive the future development of highly efficient tandem solar cells.
