Photovoltaics (PV) is increasingly becoming the most important energy source for a clean and widespread energy supply. In 2018 alone, 109GWp of PV capacity was installed globally. Every country has now realized that PV is not only ecological, but becoming extremely economical, with an average levelised cost of electricity (LCOE) of around 4ct/kWh. (In some cases, PV can reach a LCOE of around 2ct/kWh.) Bifaciality is one of the most promising technologies for driving these costs even lower. Bifacial PV systems can sometimes see gains of more than 30% and, combined with tracking, the total electrical gain can be close to 50%, which will reduce LCOE to below 2ct/kWh.
The Energy Research Centre of the Netherlands part of TNO (ECN>TNO), the International Solar Energy Research Center Konstanz (ISC Konstanz), the National Solar Energy, The National Renewable Energy Lab (NREL), Sandia National Laboratories (SNL), Institute (INES), and Zurich University of Applied Sciences (ZHAW), are proud to organise
The goal of this workshop is not only to review all existing technologies on the market, but also to set standards, to identify the market potential, and improve bankability of bifacial PV. We hope to see you at the workshop in Amstardam!

Chairmain’s Message
Bas Van Aken, ECN.TNO
Dear Bifacial Friends, I’m honored to welcome you to the 2019 Bifacial PV Workshop in the Netherlands!
Large scale bifacial PV power plants are already operating since a few years in Asia. We learned in the 5th BifiPV Workshop in Denver that bifacial is about to break through in the USA too. But what about the less sunny regions of the world?
Two years ago, Tempress opened its 400 kWp solar power plant in the Netherlands, demonstrating that bifacial PV also makes sense in a temperate, maritime climate. Last year, Next2Sun opened a 2-MW bifacial, vertical power plant in Germany. And this month saw the grid connection of a 11.75 MWp bifacial solar power plant in the Netherlands by Unisun and Jolywood.
The 6th bifacial workshop, hosted by ECN.TNO in the Netherlands, will update you on the latest developments in the field of bifacial PV. We’re scheduling a programme ranging from solar cell technology to bankability, from performance modelling to module manufacturing and system installation to characterisation and reliability. There will be ample time for interaction with the speakers during the sessions. The informal character of the workshop allows for plenty discussions and meetings during the breaks.
Sunny wishes and best regards,
Bas Van Aken, ECN.TNO – Solar Energy
Venue and Activities
Location, Dinner & Tour
Location of bifiPV workshop 2019 – Amsterdam
Amsterdam, the capital of the Netherlands, is well-known for canals lined with narrow houses and gabled facades originating in the city’s 17th century Golden Age. Its Museum District houses the Rijksmuseum with, amongst others Rembrandt’s famous Nightwatch, the Van Gogh Museum and modern art at the Stedelijk museum.
Venue of bifiPV workshop 2019 – Level Eleven
We’re hosted by Level Eleven right in the middle of Amsterdam’s sparkling city centre and directly next to Amsterdam Central Station. Level Eleven (Stationsplein 51 – 53, Amsterdam) is highly accessible for everyone. A top-level location, in every sense of the word. Amsterdam is at your feet, you can see everything from this spot. Take a look at the city from high up and think about all the things you want to experience.
Dinner of bifiPV workshop 2019 – Monday 16 September
On Monday night, the bifacial talk will continue with the workshop dinner including a 360° view over the city centre and the banks of the IJ. Watch the trains and ferries, the bikes and pedestrians below. The dinner is included in the Workshop entrance. Some additional tickets for the dinner are also available at the registration website.
Accomodation for bifiPV workshop 2019
There is a large choice of places to stay in Amsterdam, which can be found via the usual websites or apps (Booking.com was founded in the Netherlands). A good place to start planning your visit to Amsterdam is the website of the Amsterdam Tourist Office.
Tour of bifiPV workshop 2019 – Wednesday 18 September
After the workshop, there is an optional tour to ECN.TNO in Petten, including lunch on the beach and a visit to the touristic hot spot Zaanse Schans. Tour can be booked at the registration website.
On our route, we will enjoy the various landscape adaptations that the Dutch created out of necessity to defend their land from the sea and in one go invented perpendicular street patterns and claimed the tulip as national flower.
We will visit the ECN.TNO solar energy facilities, including cell and module technology laboratory facilities and outdoor characterisation (weather permitting).
Next, a short walk, 30 mins, will bring us to a beach restaurant for an informal lunch (bus transport is of course also possible).
Final destination is de Zaanse Schans: “beautiful, unique and full of windmills”, a unique piece of Dutch history on the river Zaan.
