Abstract Despite inorganic CsPbI 3− x Br perovskite solar cells (PSCs) being promising in thermal stability, the degradation and severe nonradiative recombination at interface hamper their further development. Herein, typical MXene material, that is, Ti 3 C 2 T , is employed to be buried prior absorber layer device, which multi‐functionalizes as‐prepared electron‐transfer layers by means of both fascinating preferential crystallization and/or accelerating charge extraction with respect an...
Abstract Defect state passivation and conductivity of materials are always in opposition; thus, it is unlikely for one material to possess both excellent carrier transport defect simultaneously. As a result, the use partial local contact strategies required silicon solar cells, which leads fabrication processes with technical complexities. Thus, that possesses good highly desirable photovoltaic (PV) cells. In this work, passivation‐conductivity phase‐like diagram presented...
In this study, the hydrogen-bonding interactions of three widely used diisocyanate-based hard-segment (HS) models in polyurethane, 2,4-toluenediisocyanate-methanol (2,4-TDI-MeOH), 2,6-toluenediisocyanate-methanol (2,6-TDI-MeOH), and 1,6-hexamethylenediisocyanate-methanol (HDI-MeOH), were investigated theoretically by density functional theory (DFT). The B3LYP/6-31G* method was to calculate equilibrium structures, Mulliken charges, energies, infrared (IR) spectra, good agreement with previous...
Crystalline silicon (c-Si) solar cells remain dominant in the photovoltaic (PV) market because of their cost-effective advantages. However, requirement for expensive vacuum equipment and power-hungry thermal budget surface passivation technology, which is one key enablers high performance c-Si cells, impede further reductions costs. Thus, omission high-temperature process without compromising effect highly desirable due to cost concerns. Here, we demonstrate a vacuum-free, room-temperature...
A polymer inspired by a leaf guard-cell and designed introducing supramolecular hydrogen-bonding switches moisture-sensitive SAWVP has been achieved, suggesting that hydrogen bonding can become moisture-responsive switch when its energy is smaller than the between water molecule itself.
Abstract The lack of specific knowledge the network structure in shape memory polymers (SMPs) has prevented us from gaining an in-depth understanding their mechanisms and limited potential for materials innovation. This paper firstly reveals unit-cell nanoscale morphological architecture SMPs by simulation. phase separated a segmented polyurethane (SMPU) with 30 wt% hard segment content (HSC, 4,4’-diphenylmethane diisocyanate (MDI) 1,4-butanediol (BDO)) showing good properties was...
The MDI phase in SMPUs develops a framework with netpoints evolving from spheres, to linked-spheres, linked-cylinders, and then linked-bi-crossing-cylinders.
The organic passivated carbon nanotube (CNT)/silicon (Si) solar cell is a new type of low-cost, high-efficiency cell, with challenges concerning the stability layer used for passivation. In this work, studied respect to internal and external (humidity) water content additionally long-term low moisture environments. It found that CNT/Si complex interface not stable, despite both passivation CNTs being stable on their own due providing an additional path molecules interface. With use simple...

This scalable solution‐based processing technique has the potential enable low‐cost carbon/silicon photovoltaic devices.
2D transition metal carbon/nitrides (MXenes) have lately attracted increased attention in photovoltaic (PV) because of their good optical and electrical properties. MXenes–silicon solar cells as a novel PV device are considered to be low‐cost strategy for boosting Si‐based development. Nevertheless, power conversion efficiency (PCE) large area preparation limited future applications. Here, the solubilization Ti 2 CT x (T = O, F, OH) MXene multilayer nanosheets is reported thus ability scaled...
The innate inverse Auger effect within bulk silicon can result in multiple carrier generation. Observation of this is reliant upon low high-energy photon reflectance and high-quality surface passivation. In the photovoltaics industry, metal-assisted chemical etching (MACE) to afford black (b-Si) provide a reflectance. However, an industrially feasible cheaper technology conformally passivate outer-shell defects these nanowires currently lacking. Here, introduced infiltrate nanopores with...
