Participate in the world’s largest specialist PV Solar Conferenceflags blue fullconfprog

Connect with the global PV community at EU PVSEC in September to gain knowledge, explore trends and discuss what is needed to keep up the new solar momentum in Europe.

Dates: 06 - 10 Sept 2021
Hours: Monday - Thursday 08:30 - 18:30 / Friday 08:30 - 13:10 CEST, UTC/GMT +2 hours, Paris, Berlin, Rome, Munich time

The international Conference Programme is structured in plenary, oral and visual presentations. These cover the entire range of PV research, technologies and applications with a special emphasis on the latest scientific, technological and market-related trends.

As Prof. Joao Serra, General Chair of the EU PVSEC 2021, explains in his message to the PV community: “With its strong reduction in LCOE, PV is at the forefront of new energy technologies to be a key contributor for change. PV benefits range from local energy production to large power plants. By combination with other technologies it expands its added value not only to cities, including buildings and mobility, but also to agriculture, water desalination and hydrogen production.

While solar is the most versatile and often lowest cost power generation source in Europe today, EU PVSEC continues to strengthen the importance and potential of solar among global researchers, policy-makers and industry.

The Programme for EU PVSEC 2021 online offers a carefully crafted programme of almost 900 top-level international presentations giving participants in-depth insights into the latest research in the PV solar energy sector.



Panel Discussions

This year, for the first time, EU PVSEC is offering four thematic panel discussions that address the 7 scientific conference topics and provide space to discuss them in more depth. The panellists consist of experts from industry and research as well as renowned politicians.

Thursday, 9 September 2021 | 13:30 – 15:00 Tandems: The Real Game Changer?

With silicon solar cells approaching their theoretical efficiency limit, focus is shifting to tandem technologies to continue innovation and cost reduction. While the potential is clear, many issues remain open for discussion: Which choice of materials provides the best balance between high efficiency, low production cost, high stability, and resource abundance to allow for TW-scale deployment? What is the best device concept, 2-, 3- or 4-terminal? How can we translate fundamental science and record lab efficiencies into relevant manufacturing? How can we create a healthy industrial ecosystem including research, equipment manufacturing and actual cell and module production? We would like to discuss these and other questions with you, the audience, and an exciting panel which brings together a diverse set of perspectives and experience.

Tuesday, 7 September 2021 | 13:30 – 15:00 Towards Ultimate Single-Junction Silicon Cells – Industry Perspective

Photovoltaic technology is at a historical juncture: not only PV is poised to take over the largest share of new generation capacity, starting right now, but it will also become the largest source of global electricity generation by mid-century. PV technology is also reaching amazing levels in efficiency, reaching > 80% of the theoretical efficiency limit for single-junction Silicon solar cells, and in cost, down to less than US$0.25/W for Mono-Si PV modules. Despite approaching the efficiency ceiling, Single-Junction Silicon solar cells keep improving and module cost is expected to reach US$0.10/W in the next decade. It is now time to prepare ourselves to the production and deployment of multi-TW of PV system. Will PERC continue to be the “workhorse” of the industry? What innovation can we expect in module design? Are 182mm or 210mm the ultimate wafer sizes? Will TOPCon, HJT or IBC compete for more market share? Do we need another technology? Which technology will be the ultimate single-junction device for a multi-TW market? Are these technologies developed with durability (30 … 50 years), sustainability and recycling in mind?

Monday, 6 September 2021 | 13:30 – 15:00 Managing Performance and Sustainability at the TW Scale

Part 1: Computational PV

Almost 10% of presentations at this EUPVSEC deal with advanced computing. Algorithms, big data, machine learning, artificial intelligence, image recognition and satellite data processing appear in the titles of contributions which range from solar cell modeling, manufacturing, preventive maintenance, site selection to forecasting, nowcasting, user behavior and modeling of entire electricity systems. This panel discussion aims to get the view of top experts on how the tremendous progress of computing power in the last decade has influenced the way we assess photovoltaic technology at large. And most likely the next ten years will see even more.

Can substantial cost gains be achieved? Will we have intelligent inverters which will decide on their own about self-consumption, grid-feeding or storage? Will be there new players taking on the role of utilities by optimizing the services PV systems can deliver? What about optimizing PV in cities and on cars when a 3D model of the landscape is easily available in real time?

Part 2: Resource Efficiency of PV in Production, Use and Disposal

The latest IPCC report has been published recently and there is an urgent need for action to mitigate our emissions and save our limited resources.

PV systems do contribute significantly to the solution for nature conservation. Modern eco-friendly technologies and long lasting, repairable products are required in combination with sound circular economy approaches to process the huge anthropogenic stock of valuable resources at the end of life of the PV systems.

This panel discussion aims to get the view of top experts on how PV can form an even better sustainable solution to our increasing energy hunger. The discussion will cover international policy development needs, environmentally friendly, resource efficient production approaches including novel reuse and repair concepts, and the introduction of a sound circular economy.

Main questions are:

  • How can PV products and production processes be further optimized?
  • What is required to increase service life, and introduce repairable and easy recyclable PV products?
  • Which international policies are needed to support the introduction of such products and better circularity?

These are just some of the questions the panel will discuss and give the audience a glimpse into the future of “PV everywhere”

Wednesday, 8 September 2021 | 13:30 – 15:00 PV: The Key Element Towards 100% Renewables. How to Make it Happen?

As the cheapest energy source in history, PV is redefining the way we think about energy. Will everything else have to adapt to it? This panel discussion will look into the technical and non-technical changes ahead, including grid integration, markets, policy and finance.

Full Conference Programme available

Dear PV and Energy professional,

R Kenny2019

It is with great pride that we share the full scientific programme of the 38th European Photovoltaic Solar Energy Conference, to be held 6-10 September 2021 online. We have a full and varied scientific programme which covers fields of interest to all stakeholders, ranging from concepts, materials, cells and modules, through to applications, systems, policies and markets. The programme contains three dedicated plenary sessions covering the full range of conference topics, targeted to provide an in-depth overview to the non-specialist. These will provide you with key knowledge on the present and future direction of PV, which is increasingly being recognized for its crucial role in the future sustainable integrated energy system. Oral and Visual sessions are grouped by topic and theme easily located and tracked in our programme outline and full conference programme.

Our conference offers a unique opportunity to present your work and learn more about your own area of specialization, as well as to follow developments, and meet workers, in other fields. We are aware that being online offers a different experience to a physical conference, and we have included four dedicated discussion sessions in the programme (13:30-15:00 Monday-Thursday) covering the hot issues within the different conference topics that are intended to stimulate involvement of all participants. The possibility of remote connection does enable the welcome participation of many who perhaps would not manage to attend a physical event in a far away continent, and I look forward to meeting you all online from every corner of the globe and from every time zone.
