The Helmholtz-Zentrum Berlin für Materialien und Energie (HZB) and Altatech, a subsidiary of Soitec, have launched a collaborative partnership to research and develop materials for the next generation of high-efficiency solar cells, including new classes of materials and innovative device structures for photovoltaic and photocatalysis applications.

As part of the organizations’ joint effort, Altatech will install a new single-substrate multi-chamber solution, an AltaCVD system, at HZB’s newly constructed Energy Materials Insitu Laboratory (EMIL) at the synchrotron light source BESSY II facility in Berlin. Together, HZB and Altatech will investigate new materials-deposition processes, functional interfaces and device structures for solar energy conversion and storage.

Altatech’s new AltaCVD system will be used in HZB’s EMIL lab to deposit amorphous silicon (alloys), transparent conductive oxides and ultra-thin dielectrics used in fabricating next generation solar energy devices. The CVD system will be hosted by the new EMIL building, adjacent to HZB´s third-generation storage ring BESSY II. The cluster tool will be directly connected to a state-of-the-art X-ray analytical end-station, which accesses a dedicated beam line from BESSY II. The partner organizations will conduct atomic-layer deposition, plasmaenhanced chemical vapor deposition and physical vapor deposition on substrates ranging from small research samples up to fully industry-compatible six-inch wafers and use EMIL’s outstanding analytical capabilities to analyze material and interface properties in between successive processing steps.

“EMIL aims at exploring materials for high-efficiency photovoltaic cells and new catalytic processes for future solar energy generation and storage concepts. We will develop and characterize these materials with basic energy research methods, but prepare them with industrially related methods to ensure rapid industrial implementation,” says Prof. Klaus Lips, head of the EMIL project and HZB’s Advanced Analytics Group. “The AltaCVD system provides us with a unique combination of a highly flexible design in terms of temperatures, precursors, plasma cleaning, etc. with a fully industrial-compatible deposition technology.”

“This order reinforces the AltaCVD system’s leadership position in advanced materialdeposition applications,” says Jean-Luc Delcarri, general manager of Soitec’s Altatech subsidiary. “Our collaboration with the Helmholtz-Zentrum Berlin allows us to apply our advanced material-deposition technology at a state-of-the-art synchrotron radiation facility. Together, we are opening the door to a new era in advanced renewable-energy development that will help researchers to tackle the challenges of future world energy needs.”

    The future of corals – what X-rays can tell us
    This summer, it was all over the media. Driven by the climate crisis, the oceans have now also passed a critical point, the absorption of CO2 is making the oceans increasingly acidic. The shells of certain sea snails are already showing the first signs of damage. But also the skeleton structures of coral reefs are deteriorating in more acidic conditions. This is especially concerning given that corals are already suffering from marine heatwaves and pollution, which are leading to bleaching and finally to the death of entire reefs worldwide. But how exactly does ocean acidification affect reef structures?

    Prof. Dr. Tali Mass, a marine biologist from the University of Haifa, Israel, is an expert on stony corals. Together with Prof. Dr. Paul Zaslansky, X-ray imaging expert from Charité Berlin, she investigated at BESSY II the skeleton formation in baby corals, raised under different pH conditions. Antonia Rötger spoke online with the two experts about the results of their recent study and the future of coral reefs.

    Long-term stability for perovskite solar cells: a big step forward
    Perovskite solar cells are inexpensive to produce and generate a high amount of electric power per surface area. However, they are not yet stable enough, losing efficiency more rapidly than the silicon market standard. Now, an international team led by Prof. Dr. Antonio Abate has dramatically increased their stability by applying a novel coating to the interface between the surface of the perovskite and the top contact layer. This has even boosted efficiency to almost 27%, which represents the state-of-the-art. After 1,200 hours of continuous operation under standard illumination, no decrease in efficiency was observed. The study involved research teams from China, Italy, Switzerland and Germany and has been published in Nature Photonics.
