• Lead-free perovskite solar cells
  

  Tin halide perovskites are currently considered the best alternative to lead-containing analogues, but are still significantly less efficient and stable compared to them. Now, a team led by Prof. Antonio Abate from HZB has analysed the chemical processes in the perovskite precursor solution and its more

• On the road to non-toxic and stable perovskite solar cells
  

  The promising halide perovskite materials for solar energy conversion show high efficiencies, but this comes at a cost: The best perovskite materials incorporate toxic lead which poses a hazard to the environment. To replace lead by less toxic elements is not easy since lead-free perovskites show lo more

• Efficient catalyst for water splitting
  

  Chemists at the Technical University of Munich (TUM) have developed an efficient water splitting catalyst as part of a collaborative international research effort. The catalyst comprises a double-helix semiconductor structure encased in carbon nitride. It is perfect for producing hydrogen economical more

The Chemical Elements of a Smartphone

There are an isolated few graphics online that look at elements involved in the manufacture of a smartphone – for example, this ‘Periodic Table of iPhones’ – but there’s actually remarkably little easily accessible information out there that details the specific compounds used for specific purposes more

Group 4 Elements

This latest infographic focuses on the Group 4 (Group 14 in IUPAC nomenclature) elements. One extra fact to add for the curious: although tin has the greatest number of stable isotopes, Xenon trumps it comprehensively if unstable isotopes are also included in the count, with well over 30 possible is more

The Tin Hedgehog Experiment

Here’s the start of a new series of collaborations with MEL Science, looking at a number of fun chemistry experiments and the explanations behind them. Today’s initial offering looks at how zinc pellets can be transformed into tin hedgehogs with some simple chemistry. more
