Abstract
Photorechargeable supercapacitors are promising next-generation renewable energy storage devices. Previously, a hybrid structure consisting of indium-tin oxide branched nanowires (ITO BRs) and poly(3-hexylthiophene) (P3HT) was demonstrated as a photorechargeable supercapacitor. However, the formation mechanism of photovoltage has not been studied. Herein, we experimentally investigated the photovoltage-determining parameters in the ITO BRs/P3HT photorechargeable supercapacitor by inserting a polyethylenimine ethoxylated (PEIE) interlayer or adding a phenyl-C61-butyric acid methyl ester (PCBM) electron acceptor. Coating the PEIE interlayer on ITO BRs decreased the work function by 0.5 eV and hindered the hole extraction from P3HT to ITO BRs, leading to interfacial recombination and a decrease in photovoltage. On the other hand, the addition of PCBM promoted the charge transfer of the electrons from P3HT to PCBM, enhanced the redox reaction at the PCBM/electrolyte interface, and reduced the number of accumulated electrons, leading to a decreased photovoltage. From these results, we found that two key parameters determine the photovoltage and charge storage capability; one is the interfacial recombination at the ITO BRs/P3HT interface and the other is the redox reaction at the P3HT/electrolyte interface.

Abstract
A photorechargeable device can generate power from sunlight and store it in one device, which has a broad application prospect in the future. However, if the working state of the photovoltaic part in the photorechargeable device deviates from the maximum power point, its actual power conversion efficiency will reduce. The strategy of voltage match on the maximum power point is reported to achieve a high overall efficiency (ηoa) of the photorechargeable device assembled by a passivated emitter and rear cell (PERC) solar cell and Ni-based asymmetric capacitors. According to matching the voltage of the maximum power point of the photovoltaic part, the charging characteristics of the energy storage part are adjusted to realize a high actual power conversion efficiency of the photovoltaic part (ηpv). The ηpv of a Ni(OH)2-rGO-based photorechargeable device is 21.53%, and the ηoa is up to 14.55%. This strategy can promote further practical application for the development of photorechargeable devices.

Abstract
Poly(3-hexylthiophene) (P3HT) is a typical conducting polymer widely used in organic thin-film transistors, polymer solar cells, etc., due to good processability and remarkable charging carrier and hole mobility. It is known that the ordered structure assembled by π-conjugated P3HT chains could promote the performance of electronic devices. Interfacial and confined molecular-assembly is one effective way to generate an ordered structure by tuning surface geometry and substrate interaction. Great efforts have been made to investigate the molecular chain assembly of P3HT on a curved surface that is confined to different geometry. In this report, we review the recent advances of the interfacial chain assembly of P3HT in a flat or curved confined space and its application to organic electronic devices. In principle, this interfacial assembly of P3HT at a nanoscale could improve the electronic properties, such as the current transport, power conversion efficiency, etc. Therefore, this review on interfacial and confined assembly of P3HT could give general implications for designing high-performance organic electronic devices.

Abstract
Current approaches for off-grid power separate the processes for energy conversion from energy storage. With the right balance between the electronic and ionic conductivity and a semiconductor that can absorb light in the solar spectrum, we can combine energy harvesting with storage into a single photoelectrochemical energy storage device. We report here such a device, a halide perovskite-based photorechargeable supercapacitor. This device can be charged with an energy density of 30.71 W h kg-1 and a power density of 1875 W kg-1. By taking advantage of the semiconducting and ionic properties of halide perovskites, we report a method for fabricating efficient photorechargeable supercapacitors having a photocharging conversion efficiency (η) of ∼0.02% and a photoenergy density of ∼160 mW h kg-1 under a 20 mW cm-2 intensity white light source. Halide perovskites have a high absorption coefficient, large carrier diffusion length, and high ionic conductivity, while the electronic conductivity is improved significantly by mixing carbon black in porous perovskite electrodes to achieve efficient photorechargeable supercapacitors. We also report a detailed analysis of the photoelectrode to understand the working principles, stability, limitations, and prospects of halide perovskite-based photorechargeable supercapacitors.

Abstract
Advanced solar energy utilization technologies have been booming for carbon-neutral and renewable society development. Photovoltaic cells now hold the highest potential for widespread sustainable electricity production and photo(electro)catalytic cells could supply various chemicals. However, both of them require the connection of energy storage devices or matter to compensate for intermittent sunlight, suffering from complicated structures and external energy loss. Newly developed photoelectrochemical energy storage (PES) devices can effectively convert and store solar energy in one two-electrode battery, simplifying the configuration and decreasing the external energy loss. Based on PES materials, the PES devices could realize direct solar-to-electrochemical energy storage, which is fundamentally different from photo(electro)catalytic cells (solar-to-chemical energy conversion) and photovoltaic cells (solar-to-electricity energy conversion). This review summarizes a critically selected overview of advanced PES materials, the key to direct solar to electrochemical energy storage technology, with the focus on the research progress in PES processes and design principles. Based on the specific discussions of the performance metrics, the bottlenecks of PES devices, including low efficiency and deteriorative stability, are also discussed. Finally, several perspectives of potential strategies to overcome the bottlenecks and realize practical photoelectrochemical energy storage devices are presented.
