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.

responsive batteries that enable the effective combination of solar harvesting and energy conversion/storage functionalities render a potential solution to achieve the large-scale utilization of unlimited and cost-effective solar energy and alleviate the limits of conventional energy storage devices. The internal integration of photo-responsive electrodes into rechargeable batteries with the simplest two-electrode configuration is regarded as a reliable and appealing strategy for highly-efficient and low-cost utilization of solar energy by simplifying the device architecture and improving the energy efficiency. This progress report provides a brief review on photo-responsive batteries with integrated two-electrode configuration that can achieve solar energy conversion/storage in one single device. The basic device architecture, operating principles and practical performance of various photo-responsive systems based on solar energy harvesting in various batteries including Li ion batteries, LiÀ S batteries, LiÀ I batteries, dual-liquid redox batteries, LiÀ O 2 batteries, non-Li anode-O 2 /air batteries are summarized and discussed.

Nowadays, the power conversion efficiency (PCE) of single-junction solar cells is almost approaching the theoretical ceiling of 31-33% according to Shockley-Queisser (S-Q) single-junction efficiency limitation. [2] However, the output voltage of the most efficient single-junction solar cells such as GaAs is about 1 V, which is insufficient for practical application to subsequently drive energy storage/utilization devices. Fortunately, by connecting multiple absorber layers to fabricate the tandem solar cells, the output voltage could be significantly increased as well as the PCE. According to S-Q analysis, the theoretical efficiencies of two-junction and three-junction solar cells could be as high as 42% and 49%, respectively. [3] Importantly, the output voltage of the tandem solar cells would be nearly doubled or tripled correspondingly. As an example, the open-circuit voltage (V OC ) of single line silicon solar cells is only about 0.6 V, which could be increased up to 1.21 V by stacking CdSe on the top of silicon. [4] Recently, with the rapid development of high-voltage perovskite solar cells (PSCs), the V OC of the tandem solar cells is remarkably improved. Typically, the highest V OC can reach up to 2.3 V for two-junction tandem solar cells, consisting of two CH 3 NH 3 PbI 3 (MAPbI 3 ) subcells. [5] Though higher voltage could be achieved by adding more junctions, such as 3.21 V in three-junction tandem cells, [6] 4.227 V for four-junction tandem cells, [7] 4.40 V for five-junction tandem cells, [8] and calculated 5.15 V for six-junction tandem cells, [9] yet the cost and technological requirements would increase exponentially. It is noted that although solar modules with simple serial connected design can also provide high voltage, the light management is still the same as single-junction cells, which could never beyond S-Q limitation. Tandem solar cells could provide a possibility for breaking physical limitation of traditional single-junction solar cells. Besides, tandem solar cells could also be basic unit for solar modules to obtain higher efficiency.As shown in Figure 1, tandem solar cells could deliver high PCE and V OC by segmented light adsorption. The PCE of solar cells is determined mainly by two processes: light absorption and carriers separation/collection. Usually, short-circuit current density (J SC ) would be lower than theory limit because of incomplete light absorption and sluggish collection of generated carriers, whereas a reduced Voc or fill factor (FF) reflectsThe organic-inorganic hybrid perovskite solar cells present a rapid improvement on power conversion efficiency from 3.8% to 25.5% in the past decades. Owing to the tuneable bandgaps, low-cost, and ease of fabrication, perovskites become ideal candidate materials for fabricating tandem solar cells, especially for efficient and high-voltage monolithic two-terminal devices. In this review, an overview of recent advances in various monolithic perovskitebased tandem solar cells with a focus on the key challenges is provided. Subsequent...
