Nowadays, with all their different forms, tandem cells are considered on top of the modern fields that many researchers try to explore all over the world. Both theoretical studies and applied technologies are struggling to realize the theoretical limit of the single-cell efficiency (~30%). Many kinds of tandem cells can be gathered together in different categories.
By employing a highly volatile acetonitrile(CH3CN)/methylamine(CH3NH2) (ACN/MA) solvent-based perovskite solution, we demonstrate fully solution-processed absorber, trans-port, and recombination layers for monolithic all-perovskite tandem and tri-ple-junction solar cells.

SCAPS simulation was utilized to complement previously published perovskite-on-Si tandem solar devices and explore herein viable all-perovskite 4-T mechanically stacked and 2-T monolithic non-Pb tandem structures. CsSn0.5Ge0.5I3 (1.5 eV) was used as top cell wide bandgap absorber, while CsSnI3 (1.3 eV) was chosen as bottom cell low bandgap absorber.
Organic–inorganic perovskite materials have gradually progressed from single-junction solar cells to tandem (double) or even multi-junction (triple-junction) solar cells as all-perovskite tandem solar cells (APTSCs).
In this work, 3 types of perovskite solar cell architectures i.e., single-junction, all-perovskite tandem and all-perovskite triple-junction, are modeled in SunSolve. The optimized layer thickness, reflection/parasitic absorptions, quantum efficiency, IV characteristics and power conversion efficiencies (PCE) of each cell are analyzed in detail.
Perovskite materials offer both band-gap tunability and solution processability. This unique combination of properties allows for fabrication of multi-junction solar cells using high-throughput deposition techniques such as blade coating, roll-to-roll, gravure coating or inkjet printing.
The study concludes that the design of all-perovskite double junction solar devices for achieving ultra-high efficiencies can be realized provided a bandgap of 1.8–1.9 eV for top sub-cell is used. Similarly, the design of all perovskite triple-junction solar cell requires low bandgap perovskite sub-cells having a thickness of the order 1 µm.
Research of perovskite single junction solar cells demonstrated, e.g., 4500 h of stability under illumination for PCEs >22% retaining more than 96% of the initial performance. 43 Nonetheless PSCs (and thus APTSCs) still need more robust durability in the future to reach conventional PV module stability of 20 years with over 80% of the initial PCE.
As reported by Hörantner et al., all-perovskite triple-junction solar cells employing perovskite absorbers with similar band gaps to those that we have used in the present work should be capable of outperforming single- and double-junction efficiencies.
The collective results highlight that the perovskite tandem absorber layers are sufficiently radiation-hard, but more robust, radiation-hard recombination contacts must be identified to unleash the full potential of all-perovskite tandem solar cells for space applications.
