Flexible perovskite/Cu (In,Ga)Se 2 (PVSK/CIGS) tandem solar cells (F-PCTSCs) can serve as lightweight and cost-effective power sources suitable for versatile applications; however, technical challenges impede their implementation.
The four-terminal tandem device with an efficiency of 29.02% is the second best among reported perovskite/CIGS tandem solar cells (Fig. 5d), mainly because of a lower PCE from the top PSC subcell.
Among them, PVSK/CIGS tandem solar cells (PCTSCs) are suitable for versatile applications, such as building-/vehicle-integrated PV (BIPV/VIPV), portable electronics, and aerospace PV, owing to their high performance, light weight, radiation hardness, 8 and flexibility.
Tandem solar cells have recently emerged as a research forefront due to their potential to practically surpass the inherent Shockley-Queisser efficiency limit in single-junction solar cells 1. By integrating multi-subcells with different energy bandgaps, tandem solar cells aim to enhance the utilization of the solar spectrum 2, 3.
In the recent studies, the widely employed top subcell is the wide bandgap perovskite solar cells, while the popular choices for the bottom subcells include Si (Eg ~ 1.12 eV), Cu (In,Ga)Se 2 (CIGSe, Eg ~ 1.00–1.68 eV), and narrow bandgap perovskite (Eg ~ 1.20 eV) solar cells 5, 6, 7, 8, 9, 10, 11, 12, 13, 14.
