Special Issue Information

Dear Colleagues,

Surface engineering is of great importance in efficient energy harvesting, conversion and storage, which can improve the charge generation, transfer and storage while inhibiting the charge dissipation in the triboelectric nanogenerators, organic–inorganic hybrid perovskite solar cells and supercapacitors, etc. One feasible strategy for improving the output performance of triboelectric nanogenerators is to enhance the effective contact area by fabricating microscale or nanoscale surface structure, surface functionalization to increase the surface charge density. Besides, it is critical to prepare high quality perovskite films and improved heterointerface for efficient charge separation, reduced charge migration distance, tunable optical/electronic properties and better stability in perovskite solar cells. Surface engineering can also realize the highly accessible surface area and facilitate the charge transfer between a conductive support and active materials in supercapacitors for better energy storage.

We are pleased to invite you to submit your work to this Special Issue on “Surface Engineering for Nanogenerator, Solar Cell and Supercapacitor”. The aim of this Special Issue is to present the latest progress of surface engineering in the energy harvesting, conversion and storage fields. The topic of interests for this Special Issue includes but not limited to:

  • Surface microstructure construction or regulation for triboelectric nanogenerators.
  • New techniques for surface engineering in energy harvesting, conversion and storage.
  • Optimization on the heterointerface for high-efficiency perovskite solar cells.
  • Surface functionalization in energy harvesting, conversion and storage devices.
  • Investigation on the surface properties of triboelectric materials and perovskite films.

We invite you to submit articles to this Special Issue in the section “Surface Engineering for Energy Harvesting, Conversion, and Storage”. Original research articles, communications and reviews are welcome. We look forward to receiving your contributions.

Manganese oxide has been studied as a promising supercapacitor electrode due to its high theoretical capacitance, low cost, and environmental friendliness. Supercapacitor performance such as specific capacitance, resistance, and cycle life greatly depends on the morphology and crystal structure of manganese oxide. In this study, a Mn3O4 hybrid structure was successfully synthesized using electrodeposition and successive ionic layer adsorption and reaction (SILAR) techniques which are simple, cost-effective, and low-temperature wet chemical processes. It was found that Mn3O4 morphology is different depending on manganese precursors and synthesis techniques. Sea-grape-like and bird nest-like morphologies were obtained via the electrodeposition technique, while flower-like and nanoparticle morphologies were formed via the SILAR technique using manganese acetate and manganese sulfate as precursors, respectively. The hybrid structure of the nanoparticle-decorated bird nest-like heterostructure was prepared using manganese sulfate electrodeposition and subsequent SILAR deposition of manganese acetate. X-ray photoelectron spectroscopy confirmed the Mn3O4 formation. Electrochemical properties of manganese oxide hybrid structure were systematically studied with cyclic voltammetry and galvanostatic charge–discharge, showing the highest areal capacitance of 390 mF cm−2 at 0.1 mA cm−2 with series and charge transfer resistances down to 4.55 and 4.91 Ω in 1 M sodium sulfate electrolyte.
