Impact

SolarLab was founded in 2016 as a collaboration of all the research groups in the Netherlands active in solar photovoltaic research. The SolarLab research groups demonstrate record-efficiency stable, sustainable solar cells, form a powerful ecosystem with a strong voice for PV research in NL and abroad and enhance PV collaboration in NL, share laboratories and coordinate funding streams. Solar PV, the conversion of sunlight into electricity, needs to play a major role in the conversion of our society to a sustainable way of living. The reach our climate ambition, 1000 km2 of solar panels need to be installed in the Netherlands alone. The new PV technology developed in the SolarLab research groups leads to a reduction in the land area and resources required for solar PV and a better integration into the environment. We educate the next generation of high-tech professionals in the sustainable energy sector. Many hundreds of BSc, MSc and PhD students are educated by SolarLab gruops every year. Next to that, the solar PV technology and spin-out technologies, for example microscopy techniques, developed within SolarLab add several million euros of revenue to the Dutch economy every year.

Solar cell records and key technological advances

Solar cell records are broken all over the world nearly every week. Over the years, the SOLARLab community has presented many breakthrough solar cells designs with efficiency records listed below. Most record have been broken since, by SOLARlab partners or others. SOLARLab also develops new materials and cell designs that can find their way in many different solar cell technologies. Some of these breakthroughs are listed below (incomplete list).

  • 33% efficient Si/GaAs/GaP solar cell with nanopatterned backreflector (with Fraunhofer ISE)
  • insight in ion migration for stabilization of perovskite solar cells
  • new tandem solar cell device designs
  • perovskite nanocube thin film fabrication technology
  • nanoelectrochemical growth of III-V semiconductors
  • hyperuniform light trapping patterns
  • realistic efficiency modelling of tandem solar cells
  • self-learning perovskiet solar cell materials
  • new instruments for PV materials characterization (EBSD, SEM-CL)
  • 14.8%: world record initial efficiency for double-junction thin-film silicon solar cells (with EPFL Neuchâtel)
  • 13.2%: record efficiency for amorphous silicon/polymer multi-junction solar cells (with TU/e)
  • 5.2%%: world record solar-to- hydrogen conversion efficiency for PV/PEC device based on metal-oxide photo-anode (2014)
  • 23.83%: world record c-Si heterojunction solar cell endowed with MoOx 23.83% efficiency (certified on the 13th of January 2022)
  • 29.6%: 4T tandem perovskite/c-Si solar cell (with TNO and TU/e)
  • 25.1%: 2T tandem perovskite/c-Si solar cell (with TU/e)
  • 9%: record efficiency for Sn-based perovskites (2018)
  • 19.1%: Pb/Sn based perovskite solar cells,stable up to 90% of initial efficiency under theral testing (90 min, 85°C, in nitrogen)

TNO

All records obtained with partners participating in the Solliance collaboration.

  • 30.0%: 4T perovskite/Si tandem solar cell (with TUE, TUD, IMEC), silicon bottom cell from industrial partner
