Since it is a source of clean energy, harnessing solar power is a natural solution to resolving the prevalent energy crisis. A solar cell is the most effective device to convert solar energy into electricity. Hence, a study on solar cells is the utmost area of interest in the energy sector.As illustrated in Figure 1, there are three generations of solar cells. Among these, the first-generation cells were of p-n homojunction on a silicon crystal, where the thickness of the absorbing layer was more than 180 µm. Mainly, silicon (Si) and germanium (Ge), indirect bandgap materials, assemble the cell. Single crystal silicon solar cells exhibit a conversion efficiency of about 26.7% and dominate the current solar cell market. [2] The second-generation solar cells are heterojunction solar cells using direct bandgap thin film materials (CdS, CIGS, etc.). The demerits of the first and second-generation solar cells are the cost of semiconducting materials, limited availability, and toxicity to human health. Emerging thirdgeneration solar cells act as an alternative. These include dyesensitized solar cells (DSSCs), organic photovoltaics, quantum dots, and perovskite solar cells (PSCs). Among all those, PSCs are at the center of the emerging photovoltaic technology with rapid improvement in the performance within a few years of discovering the first perovskite cell. Figure 2 depicts the different types of solar cells and their developmental trend for the past 46 years, showing that the performance of the PSCs has improved dramatically during a short period.The foundation technology for PSCs is DSSCs. In 1991, O'Regan and Grätzel developed a low-cost photochemical solar cell based on a high surface area nanocrystalline TiO 2 film sensitized with dye molecule. [4] The primary concern of DSSCs is the use of liquid electrolytes, which regenerate the dye after it injects electrons into the conduction band (CB) of the working electrodes (anode), which are mainly the thin layer of the metal oxide semiconductor. The electrolyte also acts as a hole transporting material to the counter electrodes (cathode). [5] The solid-state hole conductor emerged as a replacement to minimize leakage concerns in liquid electrolyte-based DSSCs. With several modifications in the device structures, researchers are trying to synthesize efficient DSSCs. However, the low absorption coefficientIn its initial phase in 2009, the inorganic-organic hybrid perovskite solar cells (PSCs) delivered a 3.8% power conversion efficiency (PCE), which is far below the present 25.7% PCE obtained in 2022. The significant improvement of the efficiency of PSCs in such a short period has stimulated significant interest in the photovoltaic community. However, the performance of current PSCs is behind the commercially available and widely used solar cells in terms of stability and scalability. Among various commonly studied perovskite materials, methylammonium lead iodide (MAPbI 3 ) is the most widely studied. This review will focus on the common solar cell structures (mesoporo...

“…In addition to the cascade ZnO-ZnS ETL, doping ZnO with a secondary metal is also effective to improve the interfacial stability. [87,88] In order to manipulate the unstable ZnO surface, a newcomposition cubic zinc metatitanate (ZnTiO 3 , denoted as ZTO) was employed as an excellent ETL for PSCs with the electron mobility comparable to that of ZnO (Figure 4e). [89] A dezincification method was developed to remove interfacial ZnO by acid treatment to further enhance the overall device PCE and stability (Figure 4f).…”

effects of many inorganic nanomaterials for their chemical properties for various applications. [5,6] With respect to the chemical properties of inorganic nanomaterials, catalysis is one of their most important applications. Different from homogeneous catalysts and biocatalysts that own welldefined catalytic sites and thus controllable chemical environments to induce steric or electronic effects for optimizing their catalysis, [7,8] catalytic inorganic nanomaterials often possess various illdefined interfaces. For example, by using polymeric or small organic ligands, a large variety of catalytic metal nanocrystals with controlled size, shape, and composition have been synthesized during the past few decades. [9][10][11] However, limited information on their metal-organic interfaces has been obtained for correlating their catalysis with the surface organic capping agents. Moreover, supported metal nanocatalysts play important roles in a wide range of reactions in chemical industry. However, conventional supported metal catalysts are often prepared by depositing metal precursors on supports followed by reduction, [12] leading to the ill-defined catalytic sites and also the presence of possible different catalytic pathways. In many cases, although the importance of metal-support interfaces has been identified, the ill-defined interface structure makes it extremely difficult to correlate the catalytic performances with the interfaces at the atomic level for guiding the design of better-performance catalysts. In addition to catalysis, interfacial effects also play critical roles in the overall performance of many devices. For instance, interfacial engineering has been demonstrated as an effective approach to optimize the performance of recently emerging organic-inorganic lead halide perovskite. [13] In the general configuration of perovskite solar cells (PSCs), a perovskite layer is sandwiched between n-type electron transport material (ETM) and p-type hole transport material (HTM). [14] Together with the composition and quality control of perovskite films, interfacial engineering over the perovskite with ETM and HTM as well as among crystalline domains of perovskite films has been demonstrated to be crucial for improving both the efficiency and stability of large-area PSCs toward practical applications. [3,15] With no doubt, developing comprehensive understanding of the interfaces over inorganic nanomaterials (e.g., metalorganic, metal-support interfaces) is of great importance to the The interfaces between inorganic functional nanomaterials and their surface modifiers play important roles in determining their chemical and physical properties. In numerous situations, interfaces created by organic ligands or secondary inorganic components on inorganic nanomaterials induce significant effects to promote their performances. However, it still remains challenging to understand those interfacial effects at the molecular level. Herein, strategies via the design of model inorganic nanomaterials with well-defined and detectab...

“…On the other hand, ZnO is a semiconductor that possesses a wide bandgap (3.37 eV) and high exciton binding energy (60 meV) [ 23 ]. It has been widely used in the field of piezoelectric devices, optical devices, solar cells, transparent electrodes, sensors, photocatalysts, and antiseptics due to the unique characteristics of ZnO [ 24 , 25 , 26 , 27 , 28 , 29 , 30 ].

Cellulose paper has been functionalized by nanoparticles such as Ag nanoparticles, TiO2, and BaTiO3 for versatile applications including supercapacitor, sensors, photoactivity, and packaging. Herein, zinc oxide (ZnO) nanosheet-modified paper (ZnO@paper) with excellent antibacterial properties was fabricated via a mild ZnCl2-urea eutectic solvent. In this proposed method, cellulose fibers as the raw material for ZnO@paper were treated by an aqueous solvent of ZnCl2-urea; the crystalline region was destroyed and [ZnCl]+-based cations were adsorbed on the surface of cellulose fibers, facilitating more ZnO growth on ZnO@paper. A flexible paper-based triboelectric nanogenerator (P-TENG) was made of ZnO@paper paired with a PTFE film. The P-TENG presents high triboelectric output performance and antibacterial activity. For instance, the output voltage and current of the P-TENG were 77 V and 0.17 μA, respectively. ZnO@paper showed excellent antibacterial activity against E. coli and S. aureus, suggesting that a P-TENG can restrain and kill the bacteria during the working process. The results also indicated that ZnO could improve the surface roughness of cellulose paper, enhancing the output performance of a flexible P-TENG. In addition, the potential application of a P-TENG-based pressure sensor for determining human motion information was also reported. This study not only produced a high-performance P-TENG for fabricating green and sustainable electronics, but also provides an effective and novel method for ZnO@paper preparation.
