In this paper, to improve the power conversion efficiencies (PCEs) of quantum dot-sensitized solar cells (QDSSCs) based on CdS-sensitized TiO2 nanotube (TNT) electrodes, two methods are employed basis our previous work. First, by replacing traditional single-sided working double-sided transparent TNT/ITO (DTTO) electrodes prepared increase loading amount dots (QDs) electrodes. Second, light absorption DTTO and efficiency charge separation in QDSSCs, copper indium disulfide (CuInS2) is...
Increasing environmental crises caused by exploring and using fossil fuels have compelled human being to develop innovative technologies utilize renewable sustainable energy sources. For this purpose, photovoltaic conversion of solar into electricity with cells is a promising attracting way in that clean inexhaustible. Nowadays, the bottleneck application on large scale generation still lies lacking an efficient, stable low-cost materials system for photon-to-electricity conversion....
Abstract Hole transport layer (HTL) is very important for the power conversion efficiency (PCE) and stability of perovskite solar cells (PSCs). As current state‐of‐the‐art HTL, Li‐TFSI doped spiro‐OMeTAD often suffers low conductivity hydrolysis additive Li‐TFSI, which significantly hinders further improvement PCE PSCs. Besides, conventional has no functional directly passivating crystal defects. Herein, multifunctional TiO 2 nanoparticles (NPs)‐modified CNT (CNT:TiO ) (spiro‐OMeTAD+CNT:TiO...
Abstract In recent years, halide perovskite solar cells (HPSCs) have attracted a great attention due to their superior photoelectric performance and the low‐cost of processing quality films. order commercialize HPSCs, researchers are focusing on developing high‐performance HPSCs. Many strategies been reported increase power conversion efficiency long‐term stability HPSCs over past decade. Herein, we review latest efforts chemical‐physical principles for preparing high‐efficiency in...
Metallic zinc electrode with a high theoretical capacity of 820 mAh g-1 is highly considered as promising candidate for next-generation rechargeable batteries. However, the unavoidable hydrogen evolution, uncontrolled dendrite growth, and severe passivation reaction badly hinder its practical implementations.

Abstract A 3D nanostructured scaffold as the host for zinc enables effective inhibition of anodic dendrite growth. However, increased electrode/electrolyte interface area provided by using matrices exacerbates passivation and localized corrosion Zn anode, ultimately bringing about degradation electrochemical performance. Herein, a nanoscale coating inorganic–organic hybrid (α‐In 2 Se 3 ‐Nafion) onto flexible carbon nanotubes (CNTs) framework (ISNF@CNTs) is designed plating/stripping to...
Abstract The power conversion efficiency (PCE) of 2D/3D perovskite solar cells (PSCs) is still significantly low compared with 3D PSCs due to the poor charge transport ability 2D thin films and a large number defects in films.

Hydrogenated graphene (H-Gra) has garnered significant attention as a promising two-dimensional material, with its structural characteristics and formation mechanisms explored through various experimental theoretical approaches, including sum-frequency generation (SFG) spectroscopy. Despite these efforts, the interpretation of SFG spectra remains contentious.
