EPFL perovskite solar cells reach 21% efficiency

Dec. 9, 2015
Dyesol announced that an EPFL research team established a new world record efficiency for perovskite solar cells.

Dyesol (Queanbeyan, NSW, Australia) announced that a research team headed by professors Michael Grätzel and Anders Hagfeldt at the Ecole Polytechnique Fédérale de Lausanne (EPFL; Lausanne, Switzerland) has established a new world record efficiency for its Perovskite Solar Cells (PSCs), with a certified conversion efficiency of 21.02%.

Dyesol, as a pioneer licensee of EPFL, has access to EPFL intellectual property in the field of perovskite and dye solar cells, in addition to its own IP covering materials, related processes, and photovoltaic solar cell design.

The conversion efficiency of 21.02% was certified at the laboratories of Newport Corporation in Bozeman, MT. Newport is one of a few institutions in the world that is accredited to issue certifications for such photovoltaic cells. This new conversion efficiency eclipses the previous record of 20.1%.

Professor Michael Grätzel said, "I would like to make particular mention of the very significant contribution of my colleague Professor Anders Hagfeldt and his team in achieving this world record result and I am confident that we will continue to make rapid progress that demonstrates the extraordinary commercialisation potential of this revolutionary solar technology."

Managing director Richard Caldwell also said, "With the EPFL forging ahead on efficiency and Dyesol focussing intensely on proving up the stability and durability of Perovskites, we are an excellent team to tackle the massive commercial opportunity presented by this potentially cheaper and more versatile alternative to conventional solar PV technology. The progressive replacement of fossil fuels by solar PV in many applications is not a matter of if, but when."

Grätzel is Chairman of the Dyesol Technology Advisory Board.
