To this end, we employ an unconventional structurally well-matched hybrid organic-inorganic perovskite derivative MPSnBr with large-sized weakly hybridized A-site methylphosphonium (MP) cations to construct a heterojunction with its structural analogs (MA, FA)(Sn, Pb)I to simulate the two subcells of the tandem cell. Compared with the popular ammonium-based perovskites, density-functional theory computation suggests that MPSnBr possesses a wider bandgap and lower conduction band minimum (CBM) level induced by the weak-hybrid MP cations, which can be a more suitable wide-range light absorber than its traditional ammonium counterparts. We show that such a heterostructure exhibits a desirable positive ”spike-like” BO, resulting in higher V and more effective suppression of undesirable carrier recombination. Hence, MPSnBr as a structural well-matched absorber, can potentially serve as the wide-range subcell in perovskite tandem cell devices.","PeriodicalId":18277,"journal":{"name":"Materials Today Energy","volume":null,"pages":null},"PeriodicalIF":9.3,"publicationDate":"2024-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140201339","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Considering the Li deposition is a dynamic electrochemical process, the external filed regulation has become a hotspot strategy to promote the cycling performance and safety application of Li mental anodes (LMA). Herein, we focus on the external fields involved during Li deposition, systematically summarizing the current progress of external field regulation for LMA. The mechanisms and limitations in regulating Li deposition are amply discussed. New perspectives and future research directions are also provided.

As an electron feeder, these resonance states significantly improve transport properties within the Al–BiSe semiconductors. The theoretical calculation shows the creation of the resonance states by hybridizing the dopant’s -orbitals with the host’s -orbitals near the Fermi level. The Al–BiSe semiconductors effectively moderate electron concentration and Seebeck-dependent effective mass, resulting in an ultrahigh zT of 0.57 over a broad temperature range of 300–473 K. The nanoparticle size (∼20 nm) efficiently impedes the propagation of lattice vibration, leading to an ultralow total thermal conductivity of 0.399 WmK.

However, defects remain as the crucial factor that impedes their further advancement in performance, and passivation of the interfaces (such as the buried and/or top interfaces) is regarded as one of the most effective approaches. Herein, we aim to address another important interface, namely, the indium tin oxide/electron transport layer (ITO/ETL) interface in n-i-p structured devices. Since electron transport layers are typically fabricated using commercial nano tin dioxide, which often display insufficient density. To combat this, we employ the most commonly used bathocuproine (BCP) material to treat the ITO/ETL interface. The incorporation of BCP diminishes the direct contact between the perovskite and ITO layers, while also passivating buried interface and adjusting the crystal orientation of perovskites. Furthermore, the substrate layer exhibits improved transparency, consequently elevating the utilization rate of light by perovskite. As a result, the BCP-based PSC exhibits an impressive efficiency greater than 22%, surpassing the control one of 19.91%, and which simultaneously demonstrates excellent stability. Notably, the optimization of this interface has universal applicability in the improvement of PSCs performance.","PeriodicalId":18277,"journal":{"name":"Materials Today Energy","volume":null,"pages":null},"PeriodicalIF":9.3,"publicationDate":"2024-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140127743","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, ultraviolet light and ozone (UVO) surface modification is utilized to simultaneously improve dielectric constant and breakdown strength of polyethylene (PE) films. As a result, after 3 minutes of UVO treatment, an enhanced recoverable energy density of 4.79 J/cm with a charge-discharge efficiency of >95% is obtained under 650 MV/m at room temperature (RT). Significantly, stable energy storage performance under 200 MV/m maintains throughout a broad temperature range from -90°C to 90°C and during 20000 cycles of charge-discharge procedures. According to first-principles calculations and thermally stimulated depolarization current measurements, formation of carbonyl groups (C=O) after UVO treatment could effectively passivate initial deep-level defect states caused by H vacancies, which explains the improvement in capacitive energy storage. Moreover, the metalized UVO-modified PE exhibits valuable breakdown self-clearing ability, and the self-cleared specimen maintains stable energy storage performance over 20000 cycles at 200 MV/m and RT.

However, there is a “trade-off” that the introduction of large-conjugated units aiming to ensure high hole mobility, inevitably compromises the green-solvent solubility of HTMs. In this work, a hybrid strategy of rigidity and flexibility is proposed, in which the conjugated unit is assembled by the rigid binaphthylamine core, and the amide-bond constitutes the flexible backbone. Polar solubilizing units ethylenedioxythiophene and thiophene are used as bridges to construct two kinds of polymers, cited as EDOT-SMe and T-SMe, respectively. Both polymers achieve high hole mobility, well-matched energy levels and efficient defect passivation effect toward the perovskite films. When processing the HTM films with the green solvent (2-methylanisole), the corresponding PSCs deliver fill factors as high as 82.7% for EDOT-SMe and 81.9% for T-SMe, respectively. Consequently, s of 20.25% for EDOT-SMe and 20.09% for T-SMe are realized, outperforming that of commercial polymer poly[bis(4-phenyl)(2,4,6-trimethylphenyl)amine] (PTAA, 19.71%).

The layered configuration of D18/PTQ10, with distinct crystalline domains, establishes a dedicated hole-transport pathway, while the alloyed BTP-eC9:Y6-O acceptors are evenly dispersed across the layered D18/PTQ10 donor phase. This carefully crafted morphology presents a gradient and interpenetrated donor/acceptor phase separation at an ideal length scale, which facilitates exciton dissociation, minimizes energetic disorder, and mitigates recombination. As a result, a power conversion efficiency close to 19% with excellent operational stability (extrapolated =818 h) was achieved.
