Perovskite/Silicon Tandem Solar Cells (PSTSCs) represent an emerging opportunity to compete with industry-standard single junction crystalline silicon (c-Si) solar cells. The maximum power conversion efficiency (PCE) of single junction cells is set by the Shockley–Queisser (SQ) limit (33.7%). However, tandem cells can expand this value to ~ 45%
A tandem solar cell consists of a silicon bottom cell and a perovskite top cell. Perovskite absorbs blue light (high-energy photons) best, whereas silicon absorbs red light (low-energy photons).

Perovskite/silicon tandem photovoltaics have attracted enormous attention in science and technology over recent years.

Perovskite silicon tandem solar cells are a promising technology to overcome the efficiency limit of silicon solar cells. Although highest tandem efficiencies have been reported for the inverted p-i-n structure, high-efficiency single junction perovskite solar cells are mostly fabricated in the regular n-i-p architecture. In this work, regular n-i-p perovskite solar cells with
As a result, the photocurrent of perovskite top cell is increased to match the current generated by Si bottom cell in the 2T perovskite/Si tandem solar cell. Finally, the tandem cell achieves a high Voc of 1.80 V and thus a PCE of 25.4%. 95 On the other hand, the defects at device interfaces are also harmful to device performance.

The fabrication procedure for the single-junction perovskite cells, including the substrate morphology and device active area (approximately 1 cm 2), is exactly the same as that for tandem cells. Thus, the performance of our single-junction perovskite cell can directly reflect its contribution in the tandem cell.
This paper reports the simulation of a Perovskite/Silicon tandem solar cell, based on methylammonium mixed bromide-iodide lead perovskite, and Silicon-hetero-junction (SHJ) structures as top and bottom cells, respectively, using Silvaco-atlas software.
After several years of development, the highest PCE of the perovskite/Si tandem cell has reached 29.5%, which is higher than that of perovskite- and Si-based single-junction cells.
Future challenges The record efficiencies of 29.5% on Perovskite-Si tandem solar cells are achieved using cell measuring 1.12 cm 2, produced under laboratory setting. The large-scale production requires such reliable performance on an industry standard − 60 cell module.
