“…For the simplest double‐junction tandem solar cells, monolithic two‐terminal (2 T) and mechanically stacked four‐terminal (4 T) configurations are mostly investigated. An early attempt of tandem FPSCs was proposed to develop a 4 T polycrystalline flexible perovskite/CIGS tandem device, yielding an efficiency of 18.2% . Very recently, Moore's group delivered 2 T all‐perovskite flexible tandem solar cells and pushed the efficiency up to 21.3% by incorporating an ALD‐processed recombination layer .…”

Flexible solar cells have launched potential applications in diverse areas, such as civil engineering, consumer electronics, electric automobile, and aerospace use. In recent years, perovskite solar cells (PSCs) have been successful with a rocketing power conversion efficiency (PCE) from 3.8% to 25.2% in the last decade. Due to its material flexibility, together with low‐cost and facile fabrication processes, perovskites have certainly been considered as a promising candidate for the next generation of flexible solar cells. So far, the PCE of single‐junction flexible perovskite solar cells (FPSCs) has reached 19.51%, which retains researchers' great enthusiasm for further development and applications of FPSCs. Herein, a brief review of the recent advances in the structural components of FPSCs is presented, including perovskite absorber layers, flexible substrates, transparent bottom electrodes, and charge carrier transport layers. In particular, the focus is on the development of low‐temperature fabrication processes of the aforementioned compositional layer structures. Finally, noticeable achievements and annual milestones are discussed and summarized, and suggestions for further improvement of FPSCs and their ways toward commercialization are presented.

“…Therefore, most of researches on FPSCs are focused on the methods to prepare efficient CTLs on plastic substrates, and this part will be discussed in detail in the fourth section of this review. Another drawback for the ITO‐PET and ITO‐PEN substrates is the high water‐vapor‐transmission‐rate (WVTR), which easily leads to serious instability problems due to the unstable property of perovskite absorber upon moisture . For example, the WVTR of PET with a thickness of 100 µm is as high as 1.1 g · m −2 · day −1 at 45 °C …”

“…Fan et al prepared an inverted nanocone epoxy substrate using an anodic aluminum oxide template imprint method, and the resulting FPSCs exhibited higher PCE and mechanical flexibility due to the light trapping effect and the better stress and strain relaxing ability between different layers . Other plastic substrates such as polyethersulfone (PES) film, Noland Optical Adhesive 63 (NOA 63), and the plastic front sheet used to encapsulate the flexible Cu(In, Ga)Se 2 solar cells were also utilized as the substrates for FPSCs.…”

Flexible solar cells have been considered as a promising photovoltaic (PV) technology due to their intrinsic advantages such as lightweight and bendability, which make them very convenient for transportation, installation, and integration with architectures and wearable electricity‐generating devices. As a novel PV technology being compatible with roll‐to‐roll fabrication, flexible perovskite solar cells (FPSCs) have achieved a great progress within the past few years, partially due to the superior photoelectronic properties of the halide perovskite absorber and the easy fabrication of the device. As a result, the champion power conversion efficiency of the FPSCs has exceeded 18% recently. In this review, the recent developments of FPSCs are summarized and discussed in the following four aspects: perovskite absorbers, flexible substrates, transparent conductive electrodes, and carrier transport layers, which are the main components for a FPSC device. The flexibility, stability, and other properties are also discussed in terms of the specialized FPSC devices. Finally, a rough prediction for the future development of FPSCs is provided at the end of this review.

“…Therefore, Pisoni et al prepared perovskite devices by using high-transparency and conductivity ZnO:Al (AZO) as the TCE with stable efficiency of 13.2 %. [25] Furthermore, Liang et al proposed a new metal oxide/ metal/metal oxide (OMO) laminate electrode that can replace ITO as the TCE-WO 3 /Ag/SnO 2 (WAS).

As extremely important inorganic materials, metal oxides play an irreplaceable role in solid perovskite solar cells. In this review, the preparation methods of metal oxides, their effects on the perovskite optoelectronic devices incorporated with the energy level compatibility of perovskite materials are provided. Finally, the possible reactions between interfaces during growth progress as well as passivation mechanism of some metal oxides to perovskite materials are discussed. The physical, chemical, and electrical properties of functional metal oxides endow the enhancement of the efficiency and stability of perovskite photovoltaic devices.[a] Dr.
