4. Conclusion In summary, we demonstrate the flexible perovskite/silicon tandem solar cell with a certified stabilized PCE of 22.8% and a high power-to-weight ratio of 3.12 W g −1. In addition, we find that the thickness and texture feature sizes can significantly affect the flexibility of the c-Si wafers.
To the best of our knowledge, this represents the first reported certified efficiency of a two-junction tandem solar cell exceeding the single-junction Shockley–Queisser limit of 33.7%.
The JPh in the silicon bottom cell of the thick FZ-based tandem solar cell is 19.08 mA cm −2. The reduced bottom cell thickness in the CZ-based tandem solar cell causes a lower response in the near-IR region leading to a reduced photogenerated current density of 17.81 mA cm −2.
In air without encapsulation, a tandem silicon cell retained 95% of its initial power conversion efficiency of 29% after 300 hours of operation. Science, this issue p. 1300 Tandem solar cells that pair silicon with a metal halide perovskite are a promising option for surpassing the single-cell efficiency limit.
This value surpasses the best silicon single-junction cell (26.7%) and is comparable to the best GaAs solar cell (27) at the same area of 1 cm 2. Under maximum power point (MPP) tracking in ambient air without encapsulation, a Me-4PACz tandem cell retained 95% of its initial efficiency after 300 hours.
Based on these rational approaches, the DSSC/Si tandem cell exhibited a much higher power-conversion efficiency (PCE) of 17.2% compared to the stand-alone SJ devices of DSSCs (−11.4%) or Si (−12.3%) cells. The PCE of the best tandem cell is 18.1%.
