HEMF research projects at the Helmholtz-Zentrum Berlin

Within the framework of HEMF the Helmholtz-Zentrum Berlin will establish new laboratories for the production of perovskite thin films, catalytically active nanoparticles and thin films for solar fuels. In addition and complementary to this new laboratories we will also set up facilities for synthesis and nanostructuring of conventionally and novel energy materials.

Our activities are grouped according to the following categories:

  • Materials Synthesis
  • Method Development
  • Device Fabrication and Testing

Our HEMF facilities are available at both HZB sites in Berlin-Wannsee and Berlin-Adlershof. Everything you want to know about the two HZB sites, can be found at our on-site pages, including directions for visiting.

 

To make full use of our HEMF facilities at HZB you must make sure that you adhere to several HZB safety and access regulations. All safety trainings are available from within GATE. You need to have a valid GATE account to access the online briefings.

For more information please go to our HZB Safety & Access Regulations.

Materials Synthesis

Component Fabrication

HySPRINT (Hybrid Silicon Perovskite Research, Integration & Novel Technologies) is a platform for cooperation with industrial partners where novel materials and energy-efficient process technologies for application fields such as solar energy conversion and sensor technology are being developed. Focus is currently on perovskite/silicon hybrid technology, liquid phase crystallisation of silicon, nanoimprint lithography, and prototyping using 3D micro-contacting techniques.

Nanostructured Films

The glancing angle deposition system (GLAD) offers the possibility to make large-area (>50 cm2) nanostructured arrays in a fast and controlled fashion by using various physical vapor deposition methods in glancing-angle geometry. A wide range of metal and metal oxide thin films can be deposited with simultaneous control of the chemical composition and 3D nanostructure for various applications in energy production and storage.

To create material libraries of multinary semiconductor compounds like nitrides, sulfides or chalcogenides we will build up a new laboratory for the combinatorial synthesis of energy materials (CSEM). Centerpiece of this new laboratory will be a pulsed laser deposition system (PLD). Various analytical techniques like X-ray fluorescence spectroscopy (XRF), X-ray diffraction (XRD), THz spectroscopy and microscopy will complete our new CSEM laboratory.

Nanoparticle Synthesis

Our nanoparticle synthesis capabilities are proposed for the synthesis and scale-up of nanoparticles for energy materials based on “colloidal route”. Colloidal particles, including metal nanoparticles, metal oxide nanoparticles, inorganic sulfur nanoparticles, and functional polymer colloids, can be fabricated with defined shape and morphology by controlling synthesis parameters, crystallites size and chemical composition, which can applied for applications in solar cells, solar fuels, Li-S batteries, supercapacitors and gas sensors.

The second project in "Nanoparticles Synthesis" entails the establishment of a laboratory for the synthesis and evaluation of catalysts for the electrochemical conversion of carbon dioxide. The synthetic emphasis will be on electrochemical deposition techniques, with the capability of deposition onto porous gas diffusion electrodes for use in high current reactors. The laboratory will feature state-of-the-art gas chromatography and electrochemical mass spectrometry for the on-line analysis of gaseous and liquid chemical products resulting from conversion of carbon dioxide.

Methode Development

Some of our synthesis facilities are interfacing with the synchrotron analytics beamlines at BESSY II and EMIL (Energy Materials In-Situ Laboratory Berlin), to allow extensive investigations of structural and electronic properties of these materials even during growth.

NAP-HAXPES, our new near ambient pressure hard X-ray photoelectron spectroscopy endstation at BElChem (Berlin Joint Lab for Electrochemical Interfaces) offers the unique possibility to monitor how the chemical and electronic structure changes during thin film growth under a wide range of growth conditions. It is complemented by a new synthesis module - also compatible with the CAT@EMIL endstation - in which solution-phase growth of nanoparticles can be monitored in-situ using liquid jet and/or droplet trains.

XES@EMIL, a modular experimental infrastructure that together with a roll-up HiTS spectrometer will allow for the XES and RIXS study of gases, liquids, and solid-state sample in gases and/or liquids at real atmospheric pressures.

METRIXS, a momentum and energy transfer resonant inelastic X-ray scattering setup is a photon-in/photon-out technique, allowing ambient and near ambient conditions as well as UHV and liquid conditions. METRIXS allows to explore molecular complexes, nanoparticle colloids as well as thin films in both solid and liquid aggregate states.

Device Fabrication and Testing

Device Testing

The solar fuel testing facility offers a unique possibility to carry out long-term (>100 hrs) performance, stability and efficiency measurements on large-area (≤10 cm2) photoelectrodes and devices under realistic and compareable conditions. Initial efforts will focus on water splitting, and later extended to e.g. CO2 reduction.

High sensitivity in-operando EPR allows defect mapping in energy materials and devices. We will offer also operando studies of thin film growth processes with EPR-on-a-Chip (EPRoC) and Electrically Detected Magnetic Resonance-on-a-chip (EDMRoC).
