The developed simulation model is fitted to published experimental results, and the importance of current matching in the two-terminal structure is discussed. With the texture structure optimized and considering current matching, the optimal texture structure improves J s c from 17.9 to 20.87 mA/cm 2 compared to the planar structure, as well as improving the power conversion efficiency from 25.8% to 35.9%. Furthermore, if the quality of the perovskite thin film and tunneling junction efficiency with a smaller voltage penalty can be improved, then the efficiency can be further improved to 38.13%. This indicates that this tandem solar cell still has much room for improvement.physics.app-ph; physics.app-ph; Physics - Opticsjournal article10.1063/5.01936412-s2.0-85188539693https://api.elsevier.com/content/abstract/scopus_id/85188539693
