  • Natural Chlorophyll Derivative Assisted Defect Passivation and Hole Extraction for MAPbI3 Perovskite Solar Cells with Efficiency Exceeding 20%

    • A chlorophyll derivative, sodium copper chlorophyllin (NaCu-Chl), is utilized to passivate the defects at the perovskite film surface via a solution post-treatment method. It is found that NaCu-Chl not only suppresses the defect-induced nonradiative recombination but also improves the film morphology. Moreover, NaCu-Chl treatment also facilitates efficient hole extraction from perovskite to Spiro-OMeTAD. As a result, NaCu-Chl-treated MAPbI3 PSCs produce an optimal power conversion efficiency (PCE) of 20.27% with better ambient and thermal stability. This work offers an insight into the application of natural products and derivatives for fabrication of PSCs.

  • 2023 Roadmap on molecular modelling of electrochemical energy materials
  • 2023
  • Ingår i: Journal of Physics. - : Institute of Physics Publishing (IOPP). - 2515-7655. ; 5:4
  • Tidskriftsartikel (refereegranskat)abstract
    • New materials for electrochemical energy storage and conversion are the key to the electrification and sustainable development of our modern societies. Molecular modelling based on the principles of quantum mechanics and statistical mechanics as well as empowered by machine learning techniques can help us to understand, control and design electrochemical energy materials at atomistic precision. Therefore, this roadmap, which is a collection of authoritative opinions, serves as a gateway for both the experts and the beginners to have a quick overview of the current status and corresponding challenges in molecular modelling of electrochemical energy materials for batteries, supercapacitors, CO2 reduction reaction, and fuel cell applications.

  • Discovery of a radio jet in the Cloverleaf quasar at z = 2.56
  • 2023
  • Ingår i: Monthly Notices of the Royal Astronomical Society. - 0035-8711 .- 1365-2966. ; 524:3, s. 3671-3682

    • The fast growth of supermassive black holes and their feedback to the host galaxies play an important role in regulating the evolution of galaxies, especially in the early Universe. However, due to cosmological dimming and the limited angular resolution of most observations, it is difficult to resolve the feedback from the active galactic nuclei (AGNs) to their host galaxies. Gravitational lensing, for its magnification, provides a powerful tool to spatially differentiate emission originating from AGN and host galaxy at high-redshifts. Here, we report a discovery of a jet-like radio structure in a strongly lensed starburst quasar, H1413+117 or Cloverleaf at redshift z = 2.56, based on observational data at optical, submillimetre, and radio wavelengths. With both parametric and non-parametric lens models and with reconstructed images in the source plane, we find a well-separated, kpc-scaled, single-sided radio jet located at projected to the north-west of the host galaxy in the source plane. This could indicate the co-existence of feedback from the AGN by both wind and jet in the Cloverleaf quasar.
