Dyesol Limited announced that a research team headed by Professors Michael Grätzel and Anders Hagfeldt at the Ecole Polytechnique Fédérale de Lausanne (EPFL) has established a new world record efficiency for its perovskite solar cells (PSC), with a certified conversion efficiency of 21.02%.

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%.
 
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 cell design.
 
“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 commercialization potential of this revolutionary solar technology,” said Prof. Grätzel, who is chairman of Dyesol’s Technology Advisory Board.

“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,” added Richard Caldwell, Dyesol’s managing director.
“The progressive replacement of fossil fuels by solar PV in many applications is not a matter of if, but when.”
