“…However, they have several limitations, such as high cost, limited accessibility, and short service-life, restricting their contribution to meet energy storage technologies [7]. In order to reduce the cost of electrodes, researchers have been focused on developing carbon-supported electrocatalysts that are effectively used in several energy storage technologies, such as supercapacitors, fuel cells, solar cells, and batteries, due to their outstanding low-residual current, cost-effectiveness, and long-cyclic durability [8][9][10][11][12][13][14].…”

Carbon-based nanocomposites have developed as the most promising and emerging materials in nanoscience and technology during the last several years. They are microscopic materials that range in size from 1 to 100 nanometers. They may be distinguished from bulk materials by their size, shape, increased surface-to-volume ratio, and unique physical and chemical characteristics. Carbon nanocomposite matrixes are often created by combining more than two distinct solid phase types. The nanocomposites that were constructed exhibit unique properties, such as significantly enhanced toughness, mechanical strength, and thermal/electrochemical conductivity. As a result of these advantages, nanocomposites have been used in a variety of applications, including catalysts, electrochemical sensors, biosensors, and energy storage devices, among others. This study focuses on the usage of several forms of carbon nanomaterials, such as carbon aerogels, carbon nanofibers, graphene, carbon nanotubes, and fullerenes, in the development of hydrogen fuel cells. These fuel cells have been successfully employed in numerous commercial sectors in recent years, notably in the car industry, due to their cost-effectiveness, eco-friendliness, and long-cyclic durability. Further; we discuss the principles, reaction mechanisms, and cyclic stability of the fuel cells and also new strategies and future challenges related to the development of viable fuel cells.

“…[21] Even though great progress has been achieved, the reported PCEs of inorganic C-PSCs are still unsatisfactory (<15%), which restricts its further commercialization. [9] Generally, two main reasons are responsible for the low PCE of CsPbX 3 C-PSCs: one is the narrow light absorption range due to the large E g of inorganic perovskite, and the other is the poor hole extraction and serious charge recombination at inorganic perovskite/carbon interface caused by large energy-level offset,…”

[9,10] Among all the reported inorganic CsPbX 3 perovskites, CsPbBr 3 shows superior thermal/moisture stability, but the large bandgap (E g ) of 2.3 eV can only absorb the light below 550 nm, resulting in a limited device efficiency of %11%. [11,12] CsPbI 3 has an ideal E g (%1.7 eV) which can absorb the light up to 740 nm, and corresponding C-PSC has achieved a champion PCE of 14.6%.…”

In Situ Constructing Intermediate Energy‐Level Perovskite Transition Layer for 15.03% Efficiency HTL‐Free Carbon‐Based Perovskite Solar Cells with a High Fill Factor of 0.81

Hole transporting layer (HTL)‐free, all‐inorganic CsPbX3 (X: I, Br, or mixed halides), carbon‐based perovskite solar cells (C‐PSCs) show promising prospect for photovoltaic application due to their low cost, excellent stability, and theoretical high efficiency. However, the inefficient hole extraction of the carbon electrode and relatively narrow light absorption range of inorganic perovskite limit the power conversion efficiency (PCE) of this kind of PSCs. Herein, these issues are addressed through in situ constructing of an intermediate energy‐level perovskite transition layer between CsPbI2.2Br0.8 and the carbon electrode via a facile formamidinium iodide (FAI) posttreatment strategy. It is demonstrated that the (CsFA)PbI3–xBrx film is in situ formed atop inorganic perovskite due to the ions exchange between FAI and CsPbI2.2Br0.8, which can not only broaden the light absorption edge of CsPbI2.2Br0.8 from 657 to 680 nm, but also serve as a hole transfer highway between CsPbI2.2Br0.8 and the carbon electrode, mainly due to its suitable intermediate energy‐level and effective defect passivation. Consequently, the optimized HTL‐free C‐PSC achieves a champion PCE of 15.03% with an ultrahigh fill factor of 0.81. Besides, the stability of CsPbI2.2Br0.8 film (especially under humid environment) and corresponding C‐PSC are also improved.

The construction of monolithic two‐terminal tandem solar cells (2T TSCs) offers the possibility of pursuing high power conversion efficiency (PCE) by overcoming the single‐junction Shockley–Queisser limit in photovoltaics. However, little attention is paid to simultaneously improve the stability by utilizing the complementary properties of various photoactive layers. Here, beyond the stacked photoactive layers featuring complementary absorption, all‐inorganic perovskite (CsPbI1.8Br1.2) is chosen as the photoactive layer of the front wide‐bandgap subcell for its intrinsic high thermal stability and ultraviolet (UV)‐filtering function to address the burn‐in and UV degradation of organic rear subcells. To realize their monolithic integration, the charge recombination efficiency in the interconnecting layer (ICL) between the two types of subcells is tentatively improved by surface reconstruction of all‐inorganic perovskite using trimethylammonium chloride. The repaired CsPbI1.8Br1.2 surface enables effective suppression of nonradiative recombination and facilitates hole transport, providing efficient charge recombination in the ICL in the 2T TSC. As a result, the all‐inorganic perovskite/organic 2T TSC delivers a promising PCE of 21.04%, accompanied by an ultrahigh open‐circuit voltage (Voc) of 2.05 V, which is nearly equal to the superposition of the respective Voc values of the subcells. More importantly, the 2T TSC simultaneously shows outstanding operational and UV stabilities.
