All-in-one light-driven water splitting

In the light of global climate change, there is an urgent need to develop efficient ways of obtaining and storing power from renewable energy sources. The photocatalytic splitting of water into hydrogen fuel and oxygen provides a particularly attractive approach in this context. However, efficient implementation of this process, which mimics biological photosynthesis, is technically very challenging, since it involves a combination of processes that...

New 2D Spectroscopy Methods

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy. Various methods are known in literature. But generally only the behaviour of a single excitation and its consequences are investigated. Now physicists and chemists of Julius-Maximilians-Universität Würzburg (JMU) in Bavaria, Germany, have presented two novel principles of optical spectroscopy in the journal...

Optical “Overtones” for Solar Cells

Semiconductors are nowadays the most prominent materials to convert solar light into usable electric energy. The International Energy Agency (IEA) reported that half a million solar panels were installed every day around the world last year. However, semiconductor-based solar cells still suffer from relatively low energy conversion efficiencies. The reason for that mainly lies in the fact that semiconductors efficiently convert the light from a...

Fast Energy Transport between Unlike Partners

Plants use accumulations of dye molecules, so-called light-harvesting complexes, to capture sunlight and to convert water (H2O) and carbon dioxide (CO2) to energy-rich organic compounds and oxygen (O2) through photosynthesis. For this, they have to transport the energy gained by light absorption over numerous dye molecules to the photosynthetic reaction centers. Individual dye units, so-called chromophores, are kept in close proximity by the surrounding protein...

Mimicking the ingenuity of nature

Nature shows how to do it: Photosynthesis is a process used by plants to create energy-rich organic compounds, usually in the form of carbohydrates, and oxygen (O2) from carbon dioxide (CO2) and water (H2O) driven by light. If we succeeded in mimicking this process on a large scale, numerous problems of humanity would probably be solved. Artificial photosynthesis could supply the Earth with fuels of...

Perfect light absorption

Physicists study how to achieve perfect absorption of light with the help of rough ultrathin films. Light-absorbing films can be found in many everyday applications such as solar cells or sensors. They are used to convert light into electrical current or heat. The films literally trap the light. Although such absorber films are applied widely, scientists still do not know which mechanism permits the most...
