Sulphur-doped graphene quantum dots emit a variety of colours.
A great challenge for state-of-the-art solar cells is to generate electricity in all weather. We present here the rapid conversion of carbon quantum dots (CQDs) from carbohydrates (including glucose, maltol, sucrose) an all-weather cell, which comprises a CQD-sensitized mesoscopic titanium dioxide/long-persistence phosphor (m-TiO2/LPP) photoanode, I–/I3– redox electrolyte, and platinum counter electrode. In virtue light storing luminescent behaviors LPP phosphors, generated can not only...
Multicolour emission is realized in chlorine-doped GQDs (Cl-GQDs) prepared by a facile hydrothermal method using fructose and hydrochloric acid as source materials. The average diameter of Cl-GQD about 5.4 nm with 2 at.% Cl. colour the Cl-GQDs can be tuned successively from blue to white, orange, green red simply varying excitation wavelength between 300 600 nm. multicolour attributed Cl doping, which introduces additional energy levels C π π*. should find applications bioimaging...
Abstract Bandgap‐tunable mixed‐halide perovskite materials have attracted considerable interest because of their indispensability as top counterparts in tandem solar cells. However, the soft and disordered lattice always suffers from severe phase segregation under illumination, which is particularly susceptible to residual strain. Herein, we report a strain regulation strategy by using alkenamides terminated Ti 3 C 2 T x MXenes an additive into precursor. Apart role template for grain growth...
Abstract Heat accumulation within in‐service perovskite solar cells (PSCs) under light irradiation is one imminent threat in deteriorating the persistent power output and long‐term durability. Herein, a novel strategy reported to remove dissipated heat by improving thermal conductivity diffusivity of film with multi‐walled carbon nanotubes (MWCNTs) as additives. Benefiting from interaction between MWCNTs well accelerated transfer kinetics mediated MWCNTs, this method produces high‐quality...
Abstract Perovskite‐based tandem solar cells have demonstrated high potential for overcoming the Shockley–Queisser limit. Routine bandgap (RBG, ≈1.55 eV) perovskites achieved a perfect balance between efficiency and stability. The narrow (NBG) candidates RBG perovskite‐based devices are very limited. Lead sulfide (PbS) colloidal quantum dots (CQDs) promising partner due to their broad absorption spectra. However, of perovskite/QD still lags behind. Herein, efficient perovskite/QDs...
Quaternary Cs2AgBiBr6 perovskites have been considered as a potential candidate to simultaneously resolve the lead toxicity and instability issues of unprecedented organic-inorganic hybrid halide perovskites. Unfortunately, photovoltaic efficiency is still lower owing great challenge make high-quality film with fewer defects. Herein, we demonstrate alkali metal ions including Li+, Na+, K+, Rb+ mediators regulate crystal lattice quality A less-pinhole perovskite obtained by precisely...
Exploring efficient and stable halide perovskite-based photocatalysts is a great challenge due to the balance between photocatalytic performance, toxicity, intrinsic chemical instability of materials. Here, environmentally friendly lead-free perovskite Cs
Perovskite solar cells (PSCs) have attracted extensive attention in photovoltaic applications owing to their superior efficiency, and the buried interface plays a significant role determining efficiency stability of PSCs. Herein, plant-derived small molecule, ergothioneine (ET), is adopted heal defective CsPbIBr2-based PSC improve power conversion (PCE). Because strong interaction between Lewis base groups (–C═O –C═S) ET uncoordinated Pb2+ perovskite film from theoretical simulations...
