World record perovskite mark set
The team partially behind Dyesol’s (ASX:DYE) perovskite solar panels have just set a world record for panel efficiency.
DYE told the market today that Professors Michael Gratzel and Anders Hagfeldt of the Ecole Polytechnique Federale de Laussanne (EPFL) established a new world record for perovskite panel efficiency of 21.02%.
As a guide, the average solar panel efficiency, that is the amount of energy beamed onto the surface of a solar panel against electrical output, is about 14%.
The previous record for perovskite solar was 20.1%.
While the testing was not done with DYE’s perovskite panels, as a licensee of EPFL, DYE has access to the department’s intellectual property in addition to its own.
“With the EPFL forging ahead on efficiency and Dyesol focusing 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 [photovoltaic] technology,” DYE managing director Richard Caldwell said.
Perovskite is a mineral compound which is used in DYE’s tech.
Cells made of perovskite work in much the same fashion that photosynthesis works for plants by converting the sun’s photons into carbohydrates and oxygen.
However, with DYE’s panels the leaf structure is replaced with a porous titanium nanostructure and the chlorophyll is replaced by a perovskite-laden dye.
The perovskite interacts with the photons coming in and produces an electrical current, with the circuit completed with a Hole Transport Material.
The upside of replicating a leaf-like process is that DYE’s panels can reportedly work in variable lighting conditions.
DYE’s panels are also being made to be ultra-thin, with the end goal of being able to use them within building envelopes.
