Filling in the gaps: The evolution of high-density module design

View Webinar Video

In this pv magazine Webinar, developed in partnership with Q Cells, we will examine some of the different approaches to high-density module design that are appearing on the market, placing recent progress within the context of other developments in the module market, and examining the areas where solutions are still needed.

Presentation of Q Cells

High density modules are a growing trend among manufacturers. It’s a simple premise: Reducing the gap between cells, increasing the active generation area of the modules rather than making it larger, can lead to better energy performance per square meter. But the landscape for this emerging technology is complex, manufacturers are trialing several different approaches, each with its own advantages and disadvantages.

In this pv magazine Webinar, developed in partnership with Q Cells, we will examine some of the different approaches to high density module design that are appearing on the market, placing recent progress within the context of other recent developments in the module market, and examining the areas where solutions are still needed.

We will be hearing from Bengt Jaeckel, Team Leader in Reliability of Solar Modules and Systems at the Fraunhofer Center for Silicon Photovoltaics, who will take a closer look at some of the different approaches to high density design, including shingling, paving and gapless design, and examine the broader trend toward these types of module and the advantage manufacturers are hoping to gain.

And we will then take a closer look at Q Cells latest module offering, which takes a ‘zero-gap’ approach to high density design. Global Product Manager Jürgen Steinberger will be taking us through the features of the modules and offering some insight into why Q Cells has chosen to develop a high density module, and why its gapless approach to the design will offer improved power density alongside other benefits.

Webinar content

  • Zero-gap, shingled, paved: Different high density approaches, and advantages and disadvantages of each.
  • Technical challenges to closing the gap between cells in a module.
  • Other techniques to boost module power density
  • Why watt-peak per square meter is an important factor in module design
  • The impact of larger wafer sizes

Questions can be submitted beforehand or during the webinar through a chat window.

Speakers

Jürgen Steinberger, Global Product Management, Q Cells

Jürgen has been working for Q CELLS since 2010 in several positions. Since January 2019, he is Manager of Product Management in Seoul, Korea. Prior to this position, Jürgen worked in the Technical Marketing department of the Global R&D Division in Thalheim, Germany. Jürgen graduated in Business Administration at the University of Applied Sciences Kempten, Germany in 2009.

Bengt Jäckel, Teamleader Reliability of Solar Modules and Systems, Fraunhofer Center for Silicon-Photovoltaics CSP

Bengt is working in the PV industry since 2007 and held various positions covering the whole value chain in the photovoltaic sector, starting with wafers, cells, modules and ends with large PV installations and their challenges (qualification testing, certification and inline verification). Bengt received his PhD at Darmstadt University of Technology in Materials Science in 2005, followed by a research fellow at Colorado State University in the department of Chemistry. He is convenor of the PV module group at DKE and a German representative for IEC TC 82.
