“…However, the formation of nonuniformities and pinholes during deposition of thick perovskite films can drastically reduce the device performance. The optimization of thin‐film deposition processes can be supported by specific characterization techniques, allowing for the detection of these imperfections, further improving the growth conditions and further understanding the influence of microstructure …”

Perovskite/silicon tandem solar cells have reached efficiencies above 25% in just about three years of development, mostly driven by the rapid progress made in the perovskite solar cell research field. This review aims to give an overview of the achievements made in this timeframe toward the goal of developing high‐efficiency perovskite/silicon tandem cells with sufficiently large area and long lifetime to be commercially interesting. The developments that led to the recent progress in tandem cell efficiency, as well as the factors currently still limiting their performance, including parasitic absorption, reflection losses, and the nonideal perovskite absorber layer bandgap, are discussed. Based on this discussion, guidelines for future developments are given. In addition, crucial aspects to enable the commercialization of perovskite/silicon tandem solar cells are reviewed, such as device stability and upscaling. Finally, economic considerations show how the number of steps and/or the costs associated to these steps for realizing the perovskite cell must be kept to a minimum to keep up with progress in the field of silicon photovoltaics.

“…Moreover, the band gap energy can be tuned in a wide range to meet the demands of a highly efficient solar cell. Theoretical investigations have demonstrated that these multication hybrids can greatly improve the stability and moisture resistance of PSCs [ 19 , 140 , 141 , 142 , 143 ].…”

Perovskite solar cells (PSCs) have been intensively investigated over the last several years. Unprecedented progress has been made in improving their power conversion efficiency; however, the stability of perovskite materials and devices remains a major obstacle for the future commercialization of PSCs. In this review, recent progress in PSCs is summarized in terms of the hybridization of compositions and device architectures for PSCs, with special attention paid to device stability. A brief history of the development of PSCs is given, and their chemical structures, optoelectronic properties, and the different types of device architectures are discussed. Then, perovskite composition engineering is reviewed in detail, with particular emphasis on the cationic components and their impact on film morphology, the optoelectronic properties, device performance, and stability. In addition, the impact of two-dimensional and/or one-dimensional and nanostructured perovskites on structural and device stability is surveyed. Finally, a future outlook is proposed for potential resolutions to overcome the current issues.

“…The A‐site cation species, including MA, FA, Cs, and their derivatives, have been largely employed to compositionally engineer the halide perovskite materials. [ 32–35 ] Mixing halides leads to variation in the lattice parameters, such as an increase in the cell parameter (5.68 Å→5.92 Å→6.27 Å) when the halide changes (Cl→Br→I) in the cubic phase of MAPbX 3 . [ 36 ] Such halogen mixing method fine tunes the energy gap and effectively enhances the charge transport and device stability.…”

Halide perovskites, traditionally a solar-cell material that exhibits superior energy conversion properties, have recently been deployed in energy storage systems such as lithium-ion batteries and photorechargeable batteries. Here, recent progress in halide perovskite-based energy storage systems is presented, focusing on halide perovskite lithium-ion batteries and halide perovskite photorechargeable batteries. Halide-perovskitebased supercapacitors and photosupercapacitors are also discussed. The photorechargeable batteries and photorechargeable supercapacitors employ solar energy to photocharge the battery; this saves energy and improves device portability. These lightweight, integrated halide perovskite-based systems, which are pertinent to electric vehicles and portable electronic devices, are reviewed in detail. Suggestions on future research into the design of halide-perovskite-based energy storage materials are also given. This review provides a foundation for the development of integrated lightweight energy conversion and storage materials.
