“…The Spiro-OMeTAD layer of the normal type PSC has been shown to be thick enough to cover the roughness of the perovskite layer and efficiently reduce the diffuse reflection in a reflective perovskite/silicon tandem device. 28 However, the solution for inverted PSCs in V-shaped tandem devices still needs further investigation. As the surface roughness depends substantially on the crystallization of the perovskite layer and is therefore affected by the conditions of the NiO x /perovskite interface, the modification of the NiO x /perovskite interface will be of great significance to the performances of both the perovskite and silicon sub-cells in V-shaped tandem devices.…”

“…The primary obstacle for the commercialization of this avenue is the need for an efficient spectrum splitter, which significantly increases the cost of the system. A modified method to avoid this obstacle is to use the perovskite cell as a reflective filter to absorb short wavelength light and reflect long-wavelength light to the bottom cell [55]. However, these spectrum-splitting approaches are sensitive to the angular distribution of incoming light and would thus require a tracking system.…”

Multi-junction tandem design has been proven to be an effective means to further improve the efficiency of solar cells. However, its share in the photovoltaics market at present is tiny, since the most efficient tandem device comprises III-V semiconductors, which entail the use of expensive fabrication processes. The advent of perovskite solar cells, which have revitalized the PV field with their unprecedented pace of development, promises to address this bottleneck. Perovskite materials could not only serve as the top subcell absorber for commercial solar cells including Si and copper indium gallium selenide, but could work efficiently as bottom subcells owing to highly tuneable bandgaps which extend down to the range of ~1.2 to 1.5 eV. The highestefficiency perovskite tandem to date was achieved by pairing a perovskite top cell with a Si bottom cell in a four-terminal configuration, yielding 26.4%. This review gives an overview of recent progress on the main tandem structures, and describes the detailed design improvements that have resulted in new record efficiencies. Ultimately, commercialization of these tandem solar cells relies on the scalability of perovskite technology. We, therefore, highlight the development of large-scale tandems and approaches to produce perovskite modules. We also point out the critical aspects that will require further effort and provide guidelines for future developments. The potential obstacles that will hamper the commercialization of perovskite tandems, if not adequately addressed, namely device stability and toxicity, are then critically examined. Finally, the substantial opportunities that perovskite materials open up for other solar devices with a tandem configuration are mentioned, which are attracting increasing attention.

“…The multistack tandem solar cell is an effective approach to achieve a higher PCE than single‐junction solar cells . Tandem structures including two‐terminal (2‐T) monolithic and four‐terminal (4‐T) mechanical stacks have been the primary research focus to date . An effective tandem solar cell consists of wide‐bandgap ( E g ) and low‐ E g subcells as top and bottom cells, respectively.…”

Recently, Sn–Pb low‐bandgap (Eg) perovskite solar cells (PSCs) have attracted enormous interest as an ideal bottom cell for all‐perovskite tandem solar cells. However, due to the lack of high‐performance Sn–Pb low‐Eg PSCs, the development of all‐perovskite tandem solar cells is severely constrained. Herein, the performance of Sn–Pb low‐Eg (1.2 eV) PSC is improved significantly using diluted poly(3,4‐ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) as a hole transport layer with a maximum power conversion efficiency (PCE) up to 19.58% and short‐circuit current density of 29.81 mA cm−2. The four‐terminal (4‐T) all‐perovskite tandem solar cell is constructed using an optical splitting system with this high‐efficient low‐Eg PSC as the bottom cell and a wide‐Eg (1.6 eV) PSC as the top cell. The best all‐perovskite 4‐T tandem solar cell shows a PCE of 23.26%.
