Conferences and Talks


The nanoGe Fall Meeting is a unique series of symposia focused on advanced materials preparation and fundamental properties and their applications, in fields such as renewable energy (photovoltaics, batteries), lighting, semiconductor quantum dots, 2-D materials synthesis and semiconductors fundamentals, bioimaging, among others.

Michael Graetzel will participate in the plenary session on Solar Fuel with a presentation entitled “The Genesis and Rise of Mesoscopic Photovoltaics and Perovskite Solar Cells” on October 18th, 2021.


Celebrating 20 years of AIE (aggregation-induced emission) research, the International Conference on Aggregate Science was held on July 25-28 in Guangzhou. Prof. Michael Graetzel took part as a plenary speaker among peers and discussed his revolutionary cell design presenting a completely new paradigm since it featured a three-dimensional mesoscopic junction affording very efficient solar light harvesting, in contrast to the planar p-n architecture used in conventional solar cells.

Prof. Michael Graetzel gave an online lecture at the Green Chemistry Postgraduate Summer School that took place in Venice in early July, 2021. His lecture was entitled “Mesoscopic Photosystems for the Generation of Electricity and Fuels from Sunlight”.

The School consists of 5 lecture days. The aim of the School is to disseminate good, advanced and basic chemical sciences and scientific know-how for students’ future professional careers.

Prof. Michael Graetzel is invited at the online Solar Power Technologies Conference taking place on July 5-8, 2021, where he will give an opening key note address entitled “Mesoscopic photosystems for the generation of electricity and fuels from sunlights”. The conference will consider four topics such as solar fuels and storage technologies, dye-sensitized solars cells, perovskite solar cells and solar energy policy.

Dr. Yuhang Liu talks at the Virtual workshop Tech4Win & Impressive

Dr. Yuhang Liu presented his findings at the Virtual workshop Tech4Win & Impressive: Transparent PV: Challenges and opportunities taking place online on June 11th, 2021.

The project Tech4Win (Disruptive sustainable TECHnologies FOR next generation pv WINdows) co-organises together with the IMPRESSIVE project the “Transparent PV: Perspectives and Challenges” Webinar on June 11th 2021. Tech4Win aims to develop a highly innovative transparent photovoltaic (PV) window based on the combination of an inorganic UV selective multifunctional coating (UV filter + UV selective solar) that is deposited on the first laminated glass of the window, and an organic IR selective solar cell that is implemented at the gap spacer of the window.

Michael Grätzel was an Invited Keynote Speaker at the International Conference on Hybrid and Organic Photovoltaics HOPV that took place online from the 25th May 2021 to 28th May 2021. He gave a keynote plenary talk as a leading expert on photovoltaics. The nanoGe conferences are worldwide events that cover cutting-edge scientific research topics like photovoltaics, optoelectronics, solar fuel conversion, surface science, catalysis and two-dimensional materials, among many others.

Prof. M. Graetzel gives a digital lecture to Mitsubishi Chemical Co. on April 16th, 2021

Invited by a collaborative scientist in organic Chemistry at the University of Tokyo and Mitsubishi Chemical Co., Prof. Graetzel will give a lecture on the use of molecular photovoltaics and perovskite solar cells as photosystems to produce electricity and fuels from sunlight. Invited among the world’s top scientists, he will share a perspective of the techniques with Mitsubishi Chemical Co. researchers.

Prof. Michael Grätzel attends the tandemPV2021 workshop

Michael Graetzel participated 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 contributed to the debate on Tuesday, the 13th of April 2021.

Prof. Michael Graetzel takes part in the 2nd edition of the Virtual Perovskite Conference 2021 as an invited Speaker

Prof. Michael Grätzel was one of the leading professionals in the field of perovskite optoelectronics invited to participate in the Virtual Perovskite Conference 2021 (#ViPerCon2021). The conference aims to provide an online platform to learn from the advances in perovskite research and related areas while working from home. The goal of this meeting was to discuss new challenges, explore trends and speculate on future directions of perovskite optoelectronics.
