“…On top of the glass substrate with six ITO (indium tin oxide) pixels with an active area of approximately 4.5 mm 2 , PEDOT:PSS (poly (3,4-ethylenedioxythiophene):polystyrene sulfonate) was spread using the spin-coating method. With chlorobenzene solution, P3HT (poly (3-hexylthiophene-2,5-diyl)) and PCBM ( [6,6]-phenyl C61 butyric acid methyl ester) in a weight ratio of 1:1 were spread on top of the HTL using spin-coating equipment in an inert atmosphere. For the half-organic solar cells, the preparation of samples was complete after the preparation of the AL.…”

“…Growing electrical energy consumption, as well as the demand for autonomic and automated independent power grids, has pushed scientists to investigate new ways of converting solar energy and artificial light into electricity. Furthermore, it is now becoming very important to collect electrical energy [1][2][3][4][5][6][7] using OSCs [1][2][3][4][5] located not only outdoors, but also indoors [1,2]. To improve the capability of converting light into electrical charge, and hence, implement energy harvesting phenomena, the following improvements of standard [1][2][3][4][5] and inverted [5] OSCs were proposed: preparation of photovoltaic devices on an elastic substrate [1]; printing a supercapacitor on an absorber layer for the collection of charges [2]; using gold nanograting instead of an ITO layer as an anode electrode [3]; incorporation of nanoparticles into the organic active layer for improved light absorption, charge distribution and electrical energy harvesting with the use of localized surface plasmon resonance phenomenon [4]; and using a different type of electron transport layer [5].…”

In this work, macro- and nanodiagnostic procedures for working, third-generation photovoltaic devices based on a modified polymer:fullerene (P3HT:PCBM) absorber were conducted using atomic force microscopy (AFM) and impedance spectroscopy (IS) equipment. All experiments were performed both in the dark and under irradiation with a specific light wavelength. Photoactive Kelvin probe force microscopy (p-KPFM) and impedance spectroscopy (p-IS) experiments were conducted on half- and whole-solar cell devices. Based on the p-KPFM measurements, the surface potential (SP) and surface photovoltage (SPV) on top of the active layer at the micro/nanoscale were estimated for various light wavelengths (red, green, blue, and white). For light in the red spectrum range, which was associated with an optical absorption edge and acceptor states that occurred in the band gap of the P3HT material after doping the donor polymer with iodine, the SPV was measured at levels of 183 mV, 199 mV, and 187 mV for the samples with 0%, 5% and 10% iodine doping, respectively. In addition, a macroscale investigation enabling the determination of the electrical parameters of the studied organic solar cells (OSCs) was carried out using p-IS. Based on the data obtained during p-IS experiments, it was possible to propose a series electrical equivalent circuit to define and describe the charge transfer phenomenon in the OSCs. Estimations of data obtained from the fitting of the experimental results of p-IS under white light allowed us to evaluate the average diffusion time of electric charges at 8.15 µs, 16.66 µs, and 24.15 µs as a function of organic layer thickness for the device without doping and with 5% and 10% iodine doping. In this study, we demonstrated that correlating information obtained at the macro- and nanoscale enabled a better understanding of the electrical charge distribution of OSCs for indoor applications.

At present, in response to the call of the green and renewable energy industry, electrical energy storage systems have been vigorously developed and supported. Electrochemical energy storage systems are mostly comprised of energy storage batteries, which have outstanding advantages such as high energy density and high energy conversion efficiency. Among them, secondary batteries like lithium batteries, sodium batteries, and lead-acid batteries have received wide attention in recent years. Lithium-ion batteries (LIBs) have existed for a long time. However, due to limited lithium resources worldwide, uneven distribution, and worrying safety issues, the development of LIBs has been gradually hindered. Meanwhile, sodium-ion batteries (SIBs), whose working principle is similar to that of LIBs, have been gradually emphasized by researchers due to the advantages of abundant resources and low cost. Moreover, all-solid-state sodium batteries (ASSBs), which have higher energy density, simpler structure, and higher stability and safety, are also under rapid development. Thus, SIBs and ASSBs are both expected to play important roles in green and renewable energy storage applications. This Review focuses mainly on the detailed introduction of the constituent materials of SIBs and ASSBs, analyzing the development of cathode and anode materials and the solid-state electrolytes (SSEs) in the past five years. The advantages and development direction of each SSE suitable for ASSBs are listed and remarked, and the nonactive materials such as separators and collectors are briefly mentioned. Finally, a reasonable assessment and prospects of the different materials and preparation methods are put forward.

“…Batteries energy density (ED) of supercapacitors is comparatively lower than that of batteries, and a key challenge encountered by SCs is the sluggish ion transfer rate, which can be attributed to the comparatively low electrical conductivity of their electrode materials [3]. Batteries are believed to store energy by ion intercalation or deintercalation, resulting in slow ion migration into active electrode materials and having the capacity to keep high ED [4][5][6]. However, batteries also have some limitations, including diminished performance at elevated temperatures, lower cycle performance, poor power density, and safety issues.…”

Supercapacitors are prospective energy storage devices for electronic devices due to their high power density, rapid charging and discharging, and extended cycle life. Materials with limited conductivity could have low charge-transfer ions, low rate capability, and low cycle stability, resulting in poor electrochemical performance. Enhancement of the device’s functionality can be achieved by controlling and designing the electrode materials. Graphene oxide (GO) has emerged as a promising material for the fabrication of supercapacitor devices on account of its remarkable physiochemical characteristics. The mechanical strength, surface area, and conductivity of GO are all quite excellent. These characteristics make it a promising material for use as electrodes, as they allow for the rapid storage and release of charges. To enhance the overall electrochemical performance, including conductivity, specific capacitance (Cs), cyclic stability, and capacitance retention, researchers concentrated their efforts on composite materials containing GO. Therefore, this review discusses the structural, morphological, and surface area characteristics of GO in composites with metal oxides, metal sulfides, metal chalcogenides, layered double hydroxides, metal–organic frameworks, and MXene for supercapacitor application. Furthermore, the organic and bacterial functionalization of GO is discussed. The electrochemical properties of GO and its composite structures are discussed according to the performance of three- and two-electrode systems. Finally, this review compares the performance of several composite types of GO to identify which is ideal. The development of these composite devices holds potential for use in energy storage applications. Because GO-modified materials embrace both electric double-layer capacitive and pseudocapacitive mechanisms, they often perform better than pristine by offering increased surface area, conductivity, and high rate capability. Additionally, the density functional theory (DFT) of GO-based electrode materials with geometrical structures and their characteristics for supercapacitors are addressed.
