Michael Graetzel will participate in the "Passivation strategies and compositional tuning for high efficiency perovskite PV" session at the online tandemPV 2021 workshop organized by the Helmholtz Zentrum Berlin

Photovoltaics (PV) is rapidly becoming one of the most important energy sources for a clean and widespread energy supply. In 2019 alone, 120GWp of PV capacity was installed globally. Every country has now realized that PV is not only the best solution ecologically, but also increasingly economically, with an average levelized cost of electricity (LCOE) of around 3ct/kWh, and in some cases as little as 1-2ct/kWh. End 2020 IEA declared PV the cheapest energy source ever. And we are only at the beginning of PV´s success story. In order to reach 50-80TW by 2050, further improvements in module efficiencies and reductions in the Balance of System (BOS) costs are key areas that require ongoing focus. Bifacial tandem technologies will play an important role in the coming 5-10 years and it is therefore high time to connect R&D and industry players from this emerging area to discuss standards, technology, and markets.

Prof. Michael Graetzel will contribute to the debate on Tuesday, the 13th of April 2021.
