Could production of plastic be a closed cycle and no longer dependent on crude oil?

A research team from the University of Greifswald and Helmholtz-Zentrum-Berlin (HZB) has solved the molecular structure of the important enzyme MHETase at BESSY II. MHETase was discovered in bacteria and together with a second enzyme – PETase – is able to break down the widely used plastic PET into its basic building blocks. This 3D

Lithium-ion batteries: Capacity might be increased by six times

The capacity of lithium-ion batteries might be increased by six times by using anodes made of silicon instead of graphite. A team from the Helmholtz-Zentrum Berlin (HZB) Institute of Soft Matter and Functional Materials has observed for the first time in detail how lithium ions migrate into thin films of silicon. It was shown that

Solar fuels: a refined protective layer for the artificial leaf

A team at the HZB Institute for Solar Fuels has developed a process for providing sensitive semiconductors for solar water splitting (“artificial leaves”) with an organic, transparent protective layer. The extremely thin protective layer made of carbon chains is stable, conductive, and covered with catalysing nanoparticles of metal oxides. These accelerate the splitting of water when

Hydrogen from sunlight: new efficiency record for artificial photosynthesis

An international team has now succeeded in considerably increasing the efficiency for direct solar water splitting. They are using a tandem solar cell whose surfaces have been selectively modified. The new record value is 14 % and thus considerably above the previous record of 12.4 % held by the National Renewable Energy Laboratory (NREL) in

Major leap towards graphene for solar cells

Surprising result: Graphene retains its properties even when coated with silicon Graphene has extreme conductivity and is completely transparent while being inexpensive and nontoxic. This makes it a perfect candidate material for transparent contact layers for use in solar cells to conduct electricity without reducing the amount of incoming light  – at least in theory.

World Record Solar Cell with 44.7% Efficiency

This is a major step towards reducing further the costs of solar electricity The Fraunhofer Institute for Solar Energy Systems ISE, Soitec, CEA-Leti and the Helmholtz Center Berlin jointly announced today having achieved a new world record for the conversion of sunlight into electricity using a new solar cell structure with four solar subcells. Surpassing

The best of two worlds: Solar hydrogen production breakthrough

“We’ve just created a cost-effective, highly stable, and highly efficient solar fuel device.” Using a simple solar cell and a photo anode made of a metal oxide, HZB and  TU Delft scientists have successfully stored nearly 5% of solar energy chemically in the form of hydrogen. This is a major feat as the design of
