Konstanz 2022 BifiPV PROCEEDINGS

This year’s agenda brought the best of talks on BifiPV. The talks selected represent actualized, relevant research in the fast-paced world of bifacial PV discoveries. This free event offered updated on field validation, new market trends, and knowledge developed in this past year. You can see the proceedings below, with access to slides and recordings for some of the talks.

The event took place on March 31st and April 1st of 2022 (closing the SiliconPV Workshop, allowing interested audience to attend these events in a condensed and efficient way). Attendees joined in person or online, with live discussions after each session. As part of the SiliconPV conference, the bifiPV2022 explored bifacial applications and LCOEs moving below 1USct/kWh with HSAT bifacial nPV technology.

The 2022 Hybrid bifiPV Workshop was hosted by ISC Konstanz, Germany.

Chairs Message

Dear bifiPV community,

Finally the Hybrid bifiPV Workshop 2022 will be hosted on March 31st to April 1st by ISC Konstanz, Germany. This workshop is linked to the SiliconPV conference and nPV workshop in Konstanz to enable all those who are interested to attend these events in a condensed and efficient way. bifiPV2022 will explore measurements, yield simulations, bifacial applications with LCOEs moving below 1USct/kWh with HSAT bifacial nPV technology as well as special space saving systems for e.g. AgriPV and carports.

We are looking forward to meeting you in Konstanz!
