PEPPERONI, a four-year Research and Innovation project co-funded under Horizon Europe and jointly coordinated by Helmholtz-Zentrum Berlin and Qcells, will support Europe in reaching its renewable energy target of climate neutrality by 2050. The project will help advance perovskite/silicon tandem photovoltaics (PV) technology’s journey towards market introduction and mass manufacturing.

PEPPERONI‘s goal is to identify and address the barriers to tandem solar technology’s market introduction, and ultimately lay the foundations for new production capacity in Europe. A pilot line enabling this development will be established at Qcells’ European headquarters in Thalheim, Germany. The project began on 1 November 2022, with the long-term vision of enabling European industrial leadership on PV production in the global market.  

Within PEPPERONI, a pilot line for industrial-type tandem cells will be established at the Qcells European headquarters in Thalheim, Germany, and will feature innovative equipment, processes and materials to produce high-efficiency tandem cells and modules The project aims to scale up the active area of perovskite/Si tandems from the 1cm2 of today’s record devices to industry-relevant dimensions. PEPPERONI’s approach promises a fast and cost-competitive route to mass-production of PV modules of high performance and long durability.

Fabian Fertig, Director Global R&D Wafer & Cells at Qcells, said: “Qcells is proud to be part of the PEPPERONI consortium with its world-class technology partners. This research promises to break new ground in the advancement of perovskite-silicon tandem solar cell and module technology. At a time of unprecedented pressures on the current energy system, it is exciting to realise this first and transformative step towards industrial-scale manufacturing of next-generation PV technology in Europe.”

Bernd Stannowski, head of group Industry compatible processes, solar cells and modules at HZB added: “At HZB we have developed the tandem technology to world-record efficiency level on lab scale. We are now looking forward to cooperate in the PEPPERONI consortium with partners from science and industry to jointly scale this new and very promising technology up and transfer it to industry.”

About the consortium

PEPPERONI combines European knowledge and expertise from fundamental research to small-scale testing and development of solar cells all the way to high-throughput industrial manufacturing of large solar modules. The PEPPERONI consortium counts 17 partners from 12 countries spanning across Europe. PEPPERONI is co-funded by the EU under Horizon Europe and supported by the Swiss State Secretariat for Education, Research and Innovation (SERI).

    Stability of perovskite solar cells reaches next milestone
    Perovskite semiconductors promise highly efficient and low-cost solar cells. However, the semi-organic material is very sensitive to temperature differences, which can quickly lead to fatigue damage in normal outdoor use. Adding a dipolar polymer compound to the precursor perovskite solution helps to counteract this. This has now been shown in a study published in the journal Science by an international team led by Antonio Abate, HZB. The solar cells produced in this way achieve efficiencies of well above 24 %, which hardly drop under rapid temperature fluctuations between -60 and +80 Celsius over one hundred cycles. That corresponds to about one year of outdoor use.

    Scientists Develop New Technique to Image Fluctuations in Materials
    A team of scientists, led by researchers from the Max Born Institute in Berlin and Helmholtz-Zentrum Berlin in Germany and from Brookhaven National Laboratory and the Massachusetts Institute of Technology in the United States has developed a revolutionary new method for capturing high-resolution images of fluctuations in materials at the nanoscale using powerful X-ray sources. The technique, which they call Coherent Correlation Imaging (CCI), allows for the creation of sharp, detailed movies without damaging the sample by excessive radiation. By using an algorithm to detect patterns in underexposed images, CCI opens paths to previously inaccessible information. The team demonstrated CCI on samples made of thin magnetic layers, and their results have been published in Nature.
