“…The 2T perovskite/Si Eff record of 33.7% is currently held by KAUST [8]. The 4T perovskite/Si tandem Eff of 30.3% was reported by Duong et al [11], while 27.0% 4T perovskite/CIGS tandem was reported by Wahl et al [12]. Perovskite top cell bandgap was not reported for KAUST 2T tandem while the bandgap was 1.55 eV in the 4T perovskite/Si device and 1.65 eV in the 4T perovskite/CIGS device, both of which are close to the optimal according to our calculation.…”

Tandem solar cells have received a lot attention from academia and industrial researchers as the potential next-generation PV technology, with higher efficiency above the limit of single-junction solar cells. Thin-film/thin-film (TF/TF) tandems are attractive due to similar toolset and processes producing the top and bottom cells, which improve scalability and promote cost reduction compared to thin-film/wafer tandem technologies. TF/TF/tandems additionally offer more absorber bandgap flexibility that promotes photovoltaic conversion efficiency optimization. Many materials not suitable for single junction solar cells can be explored as tandem top or bottom cells. To assess the practical efficiency potential of tandem solar cells limited by non-ideal material and device quality, we present a Shockley-Queisser-like efficiency calculation for tandem devices consisting of non-ideal top and bottom cells and with a range of absorber band gaps. The non-ideality is introduced through an experimentally measurable external radiative quantum efficiency (ERE). We find that a range of top and bottom cell band gaps enabling the highest tandem efficiency shifts from the ideal Shockley-Queisser case and depends on the top and bottom cell ERE. Furthermore, tandem cell efficiency greater than 37% can be achieved with very modest top/bottom cell EREs, for example of only 0.008%/0.5% which is typical for CdTe/CIS cells. Our results indicate that high efficiency tandem solar cells have good probability to be manufactured at high volume within a foreseeable future, despite non-ideal material and device quality due to early stages of development or constraint by manufacturing requirements.Finally, we review a number of mature and emerging thin film absorber material candidates for tandem applications. We discuss properties of these materials and the corresponding device performance as well as the associated technological challenges. We concludes on the promise of each of these materials for tandem applications that is expected to provide guidance to the photovoltaic research community.

Surface passivation and interface modification are effective strategies to acquire outstanding performances for perovskite solar cells (PeSCs). To suppress charge recombination and enhance the stability of the perovskite device, a hydrophobic two-dimensional (2D) perovskite is presented to construct a 3D–2D composite perovskite, passivating the perovskite surface/interfacial imperfection. Herein, a 3D–2D heterojunction perovskite is in situ synthesized on a 3D surface to maximize the charge transport and environmental stability. Through optimizing the annealing procedure systematically, the champion 3D–2D carbon-based PeSC achieves a power conversion efficiency of 17.95% and has wonderful long-term stability. Especially, an improved 3D–2D (3D–2D+) PeSC from restrict annealing even maintains 96.2% of the initial efficiency in air over 800 h and 90% efficiency under continuous 70 °C heating for 10 h owing to the passivation of the surface and thorough crystal boundary for the 3D–2D+ perovskite. The strong environmental stability of 3D–2D PeSCs has provided a wider avenue for fully low-temperature carbon-based PeSCs.
