The depth-dependent defect manipulation strategy using binary modulators with selective penetrability within perovskite films can concurrently passivate the defects both in bulk and at interfaces, boosting efficiency of solar cell to 24.36%.
The benefits of excess PbI2 on perovskite crystal nucleation and growth are countered by the photoinstability interfacial in solar cells (PSCs). Here we report a simple chemical polishing strategy to rip crystals off surface decouple these two opposing effects. results favorable exhibiting enhanced luminescence, prolonged carrier lifetimes, suppressed ion migration, better energy level alignment. These desired translate into increased photovoltages fill factors, leading high-performance...
Perovskite light-emitting diodes (PeLEDs) are the next promising display technologies because of their high color purity and wide gamut, while two classical emitter forms, i.e., polycrystalline domains quantum dots, encountering bottlenecks. Weak carrier confinement large leads to inadequate radiative recombination, surface ligands on dots main annihilation sites for injected carriers. Here, pinpointing these issues, we screened out an amphoteric agent, namely, 2-(2-aminobenzoyl)benzoic acid...
Abstract Additive engineering has emerged as one of the most promising strategies to improve performance perovskite solar cells (PSCs). Among additives, nanocrystals (NCs) have a similar chemical composition and matched lattice structure with matrix, which can effectively enhance efficiency stability PSCs. However, relevant studies remain limited, them focus on bromide‐involved NCs, may undergo dissolution ion exchange within FAPbI 3 host, potentially resulting in an enlarged band gap. In...
Suppressing side reactions led to the formation of rational Dion–Jacobson 2D/3D surface heterostructures, achieving an optimal PCE 23.05% (certified 22.58%) for 1.68 eV perovskite solar cells.
Surface ligand chemistry is vital to control the synthesis, diminish surface defects, and improve electronic coupling of quantum dots (QDs) toward emerging applications in optoelectronic devices. Here, we successfully develop highly homogeneous dispersed AgBiS
The flexible job shop scheduling problem (FJSSP), which can significantly enhance production efficiency, is a mathematical optimization widely applied in modern manufacturing industries. However, due to its NP-hard nature, finding an optimal solution for all scenarios within reasonable time frame faces serious challenges. This paper proposes that transforms the FJSSP into Markov Decision Process (MDP) and employs deep reinforcement learning (DRL) techniques resolution. First, we represent...
High-efficiency metal halide perovskite solar cells (PSCs) include the rigid substrates with low thermal-expansion coefficients (TECs), resulting in a significant TEC mismatch perovskites high TECs at the...
Chronic kidney disease (CKD) carries the highest population attributable risk for mortality among all comorbidities in chronic heart failure (CHF). No studies about association between inferior vena cava (IVC) diameter and all-cause patients with comorbidity of CKD CHF has been published. In this retrospective cohort study, a total 1327 were included. All underwent standardized echocardiography examination data on demographic characteristics, medical history, laboratory tests recorded....
Robust tracking control for switched linear systems with time-varying delays is investigated. Sufficient conditions the solvability of robust problem are developed. Average dwell-time approach and piecewise Lyapunov functional methods utilised stability analysis controller design, free weighting matrix scheme, switching laws obtained such that weighted H∞ model reference performance satisfied. By using inequalities, design can be solved efficiently. A simulation example shows effectiveness...
