Abstract Lead chalcohalides (PbYX, X = Cl, Br, I; Y S, Se) is an extension of the classic Pb chalcogenides (PbY). Constructing heterogeneous integration with PbYX and PbY material systems makes it possible to achieve significantly improved optoelectronic performance. In this work, we studied effect introducing halogen precursors on structure classical PbS nanocrystals (NCs) during synthesis process realized preparation PbS/Pb 3 S 2 core/shell for first time. The can effectively improve their...
Abstract Although lead sulfide (PbS) colloidal quantum dot (CQD) solar cells demonstrate excellent storage stability under ambient conditions, the operational is still rather poor for devices based on both organic or inorganic hole transport layer (HTL), seriously limiting their practical applications. In this work, it find that CQD/polymer HTL bottom interface and polymer HTL/electrode top are critical factors device performance stability. By proposing a double‐side interfacial engineering...
Abstract Chiral hybrid organic‐inorganic perovskites (HOIPs) have emerged as promising materials for optoelectronic and spintronic applications, leveraging unique properties such circularly polarized luminescence (CPL), nonlinear optical (NLO) emission, chiral‐induced spin selectivity (CISS). However, challenges remain in stabilizing these under environmental stresses precisely controlling chirality scalable use. This review summarizes five main strategies to induce HOIPs, i.e., direct...
Quantum Dot Solar Cells To overcome the performance limitations of PbS colloidal quantum dot solar cells (CQDSCs), in article number 2201676, Qing Shen and co-workers use synergistic effects three interface engineering to drastically improve balance charge carrier extraction throughout device while minimizing non-radiative recombination, resulting a record >15% power conversion efficiency for CQDSCs.
We found that the Sn halide perovskite became stable in air when Pb was added. In this report we discuss photovoltaic performances for binary MASnPbI (MA:methylammonium) solar cells (4.2% efficiency) with gradient structure from bottom to top. addition, also reported organic amine free-CsPbI about 2-4 % efficiency. Urbach energy measurement suggested lowering defect density of and CsPbI are needed enhancing
Based on the adhesion of polyethyleneimine (PEI), a novel PEI/zein co-modified core-shell stationary phase (PEI/Zein@SiO2) was prepared by doping zein to form composite modification layer. The achieved effective separation nucleosides, bases and antibiotics in hydrophilic interaction mode account groups coating. With hydrophobicity zein, flavones could be separated reversed-phase mode. In short, analysis hydrophilic/hydrophobic compounds were accomplished excellently PEI/Zein@SiO2 column...
Abstract The exploration of nontoxic Sn‐based perovskites as a viable alternative to their toxic Pb‐based counterparts has garnered increased attention. However, the power conversion efficiency perovskite solar cells lags significantly behind counterparts. This study presents ternary passivation strategy aimed at enhancing device performance, employing [6,6]‐phenyl‐C61‐butyric‐acid‐methyl‐ester (PCBM), poly(3‐hexylthiophene) (P3HT), and indene C60 bisadduct (ICBA). These components play...
As a safer and more environmentally friendly alternative to lead-based perovskite, lead-free tin halide perovskite solar cells (PSCs) have gained significant attention. However, these faced challenges, including poor quality stemming from easy oxidation fast crystallization, resulting in rough surface morphology with numerous defects. To address issues, we developed strategy utilizing polysilanes, specifically Poly-methyl-phenyl-silane (PMPS) Deca-phenyl-penta-silane (DPPS), enhance the of...
Absorption edge of perovskite (PVK) solar cells consisting MAPbI3 is 800nm. According to our simulation, light harvesting in the area near IR also necessary for enhancing efficiency more. We have already reported that mixed metal (MAPbSnI3) shows photo-conversion region (1-6). The short circuit current (Jsc) was high, reaching 30 mA/cm2 because wide range harvesting. However, open-circuit voltage (Voc) lower than 0.3 V and estimated loss 0.6-0.7 V, which much larger (0.4 V), suggesting...
