Energy Materials In-situ Laboratory Berlin – EMIL

Albert-Einstein-Str. 15

Description
Description of the infrastructure:
EMIL at BESSY II uniquely combines industry-relevant deposition tools that are in-system connected to off- and on-synchrotron analytics providing a complementing set of photon-in – electron-out and photon-in – photon-out spectroscopies that make full use of EMIL’s “two-colour” beamline, allowing for ’depth-dependent’ characterisation of thin-film layer stack samples using photons from the soft (80 eV) to the hard (10.000 eV) X-ray energy regime.
Services offered by the infrastructure:
Recently, EMIL’s UHV-based analysis setup was equipped with the required auxiliary infrastructure to allow for the characterisation of optoelectronic devices while applying a BIAS and/or application of illumination, paving the way for operando studies of photovoltaic (PV) materials and structures. Additionally, the recently commissioned OÆSE end station enables operando studies of energy storage and hydrogen producing systems with the potential to also enable in-situ studies of corrosion processes relevant for heat storage used in concentrated solar power (CSP) plants.
Support offered under this proposal:
Available services include mail-in/out or on-site activities, off- or on-synchrotron analytics with or without deposition activities. Experiment and operando cell design, deposition, measurement, data management, and evaluation support is routinely offered. Synchrotron experiments have to go through the bi-annual GUP process of BESSY II.
Extraordinary scientific aspects/possibilities of the infrastructure not available at other infrastructures:
- (1) EMIL offers a suite of complementary X-ray spectroscopic analytics.
- (2) The “two-colour” EMIL beamline provides X-rays in the soft and hard X-ray regime.
- (3) EMIL combines unique analytics with industry-relevant preparation.
- (4) EMIL allows the study of materials under operating conditions relevant for PV, energy storage, and hydrogenproducing systems.
