“…The overall PCSE is determined by both the PCE in the PSM and the ESE in the AIB. [9,10,14,20,24,27,28,[33][34][35] Note that, in some literature the SBCCE was also used to indicate the performance, that is the ratio of charged energy over solar energy, with the efficiency of 14.5% reported. Furthermore, the high ESE (η 2 ) of the AIB released most of the stored electrical energy during discharging, which also contributed to the enhanced final overall PCSE (η 3 ).…”

abundant renewable energy source, the solar-rechargeable electric energy storage systems (SEESSs), which convert solar radiation to electricity via the PV components while the complementary ESSs directly store the as-generated electrical energy, is one of the most promising nextgeneration power sources. [5][6][7] Considerable research efforts have been devoted to the development of high-performance SEESSs to meet the diverse energy demands, which require both high power density and high energy density. [4,8] However, the state-of-the-art SEESSs consisting of photovoltaics and lithium-ion batteries (LIBs) have fundamental limitations such as low power density (Scheme 1a) and poor energy storage efficiency (ESE) under high charge-discharge rate because of the limited rate performance of LIBs. [4,5] For example, the energy density and ESE of a LIB only retain less than 50% and 60% of its original values when the current density increases from 85 to 850 mA g −1 . [9] To address these issues, much effort has been made to exploring combination of PVs with supercapacitors (SCs), which show excellent power density. [10][11][12] Nonetheless, the PVs-SCs systems still face a number of challenges including the low operation voltage (mostly below 0.8 V), and more critically, limited energy density (usually lower than 15 Wh kg −1 , Scheme 1a). [13,14] The emerging aluminum ion batteries (AIBs) showing fast chargedischarge feature provide a new avenue to achieve both high power density and large energy density, leading to constantly high ESE under ultrahigh charge-discharge rates. [15] Other important merits such as abundant Al resources, increased safety, and long cycling stability together make AIBs promising energy storage candidates for portable SEESSs, but their use for next-generation SEESSs has yet been reported. [16][17][18][19] In addition to the improvement of energy storage part, optimized modulation is also urgently required for the portable SEESSs, to achieve higher overall photoelectric conversion and storage efficiency (PCSE). [20] One major obstacle in achieving efficient solar-charging is the incompatible current-voltage characteristics between multi-junction PVs and ESSs. [21] The mismatch between the maximum power point (MPP) of PV and charge voltage of ESS results in significantly reduced solar to battery charging efficiency and thus a lower overall PCSE. [11] Furthermore, the external electrical circuit connecting the PVs The solar-rechargeable electric energy storage systems (SEESSs), which can simultaneously harvest and store solar energy, are considered a promising next-generation renewable energy supply system. However, the difficulty in meeting the demands of higher overall photoelectric conversion and storage efficiency (PCSE) with both high power density and large energy density in the current SEESSs severely limit their practical application. Herein, a new class is demonstrated of portable and highly efficient SEESS that uniquely integrates a perovskite solar module (PSM) and an aluminum-ion batter...

vehicles. [4,6,7] Although electric vehicles do not produce carbon emission during consumption, they are charged using grid electricity which is produced from fossil fuels with huge carbon emission. Therefore, the benefit of deployment of electric vehicles for energy sustainable future seems rather irrelevant unless they are charged using electricity generated from renewables. In addition, large scale applications of battery-based electric vehicles is still challenging because of the inflexibility for charging stations. [8] Therefore, solar PV charging of LIBs can greatly enhance the popularity of electric vehicle market.The market for low power electronics is huge due to their numerous applications. The self-charged LIBs can play a vital role in achieving a reliable performance for portable electronics. The self-charged LIBs as independent energy sources are also beneficial to sensor network applications where a continuous operation of the sensors is required. Successful implementation of this technology in low power applications will inspire additional research to utilize this system for high power applications such as electric vehicles and grid storage.Low cost, high efficiency solar cells such as perovskite solar cells (PSCs) [9][10][11][12] and dye sensitized solar cells (DSCs) [13][14][15][16] have potential as charging sources to self-charge LIBs. Most of the literature reports till now have been focused on use of solar energy for capacitor-based energy storage. [17][18][19][20][21][22][23][24][25][26][27] Only a few reports have been published using solar energy to charge batteries. In 2012, an integrated power pack consisting of TiO 2 nanotube-nanorod based tandem solar cells on top of titanium substrate with TiO 2 nanotube/LiCoO 2 LIB on bottom was reported. [28] The LIB was charged to 3 V in 8 min and obtained a discharge capacity of 33.89 µA h under 100 µA discharge current. However, the overall photoelectric conversion and storage efficiency was only 0.82%. In 2014, a device was fabricated integrating a dye sensitized photoelectrode into a lithium oxygen battery. [29] The photocharging led to decrease in charging overpotential from 3.8 to 3.4 V. Similar work was reported with integration of dye sensitized photoelectrode in a LiI redox flow battery via linkage of I 3 − /I − based catholyte. The charging voltage was reduced from 3.6 to 2.9 V and this charging voltage reduction translated to an energy saving of ≈20% compared to conventional Li-I batteries. [30] These devices however still require external charging source to fully charge the battery. In Solar cells become a viable energy source to charge lithium ion batteries.Here a simple and efficient photocharging design approach is demonstrated, where a promising low cost single junction solar cell such as perovskite solar cell or dye sensitized solar cell efficiently charges a Li 4 Ti 5 O 12 -LiCoO 2 Li-ion cell using a DC-DC voltage boost converter. The converter boosts the low input voltage of a single junction solar cell to charge a lithium ion c...

“…

cheap technologies to integrate solar cells with secondary batteries is a viable solution for the desirable application of solar energy.

In a typical natural process, the plants can store the solar energy in carbohydrates by photosynthesis. Herein, the key issue is the transportation of the photogenerated electrons from the solar cell side to the energy storage electrodes, which are usually metal oxides, [13] hydrogen storage materials, [14] carbon materials, [15] and photocatalysts [16][17][18][19][20][21][22][23] in different liquid electrolytes. Among these modes, external connected mode (ECM) is widely used for commercial solar energy storage system, which usually consists of individual Si-based solar cells and secondary batteries (Li-ion batteries [1][2][3][4][5][6] or redox flow batteries [7][8][9][10][11][12] ).

Solar cells and rechargeable batteries are two key technologies for energy conversion and storage in modern society. Here, an integrated solar‐driven rechargeable lithium–sulfur battery system using a joint carbon electrode in one structure unit is proposed. Specifically, three perovskite solar cells are assembled serially in a single substrate to photocharge a high energy lithium–sulfur (Li–S) battery, accompanied by direct conversion of the solar energy to chemical energy. In the subsequent discharge process, the chemical energy stored in the Li–S battery is further converted to electrical energy. Therefore, the newly designed battery is capable of achieving solar‐to‐chemical energy conversion under solar‐driven conditions, and subsequently delivering electrical energy from the stored chemical energy. With an optimized structure design, a high overall energy conversion efficiency of 5.14% is realized for the integrated battery. Moreover, owing to the self‐adjusting photocharge advantage, the battery system can retain high specific capacity up to 762.4 mAh g −1 under a high photocharge rate within 30 min, showing an effective photocharging feature.
