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.
