New Record Efficiency for Dye Solar Cells
Sydney, Australia, 11 July 2013 - Announced today in the prestigious
scientific journal, Nature, is a paper by a team led by the 'Father of DSC'
Professor Michael Graetzel describing a new deposition process to create
the light harvesting pigment for solid-state dye solar cells. Cells
fabricated using this technique and incorporating Dyesol's key DSC input
materials and specially formulated 18NR-T Titania Paste have established a
new world record efficiency of 15% for a solid-state Dye Solar Cell (DSC).
'The recent breakthroughs in solid-state Dye Solar Cell technology are
truly astonishing. This is the dawn of a new age in efficient and
affordable renewable energy', said Dyesol Executive Chairman, Richard
Caldwell.
'The EPFL and Professor Graetzel choose Dyesol as their materials supplier
for achieving best results and, most importantly, for commercialisation
projects, reproducible results. These are the same benefits that we will
deliver to our major project partners as Dyesol has ongoing access to this
improved technology and the arguments for large scale industrialisation are
now very compelling.'
Professor Graetzel responded: 'Our research work on solid-state dye
sensitised solar cells is now achieving efficiencies exceeding 15% and our
cells have been externally validated with a world record of 14.1%. At
these efficiencies the technology is extremely competitive with
conventional solar cells particularly when you consider dye sensitised
solar cells do not need perfect sunlight conditions to effectively produce
energy. In the task of scale up from small laboratory sized cells to
industrial scale, we are particularly encouraged by the program from Dyesol
to allow commercial deployment of this game changing technology in the
shortest possible timeframe.'
This independently certified efficiency result eclipses all previous
certified public records and is now the official world-record for Dye Solar
Cell technology performance. The DSC world record efficiency result of
14.1% catapults the energy output of DSC devices to the next level. It is
relatively cheap and provides competitive efficiency. One of the many
advantages DSC technology offers over traditional silicon solar panels is
the consistent energy output in low-light, dawn, dusk, cloudy,
indoor/artificial, and shaded or indirect-light conditions. This means
that the cumulative seasonal energy output from DSC over the course of a
cloudy autumn, dreary winter, and whole year is much greater.
The two-step deposition process highlighted in EPFL's report published in
Nature is, importantly, reproducible - a crucial factor for
commercialisation of any technology requiring large scale quantities of
product to satisfy a mass-market.
This important technology breakthrough follows two other recent
announcements from Australian clean-tech and award-winning solar technology
innovator, Dyesol Ltd (ASX: DYE). Dyesol is working closely with EPFL and
advancing commercialisation of the mesoscopic technology called Dye Solar
Cells by embedding the revolutionary technology onto manufacturing
partners' building products, such as steel roofing and glass building
façade to meet the growing demand for building integrated photovoltaic
products which turn the building envelope into an active power generator
for building occupants and the grid.

About EPFL
DSC technology was invented at the Institute of Physical Chemistry, of the
Swiss Federal Institute of Technology in Lausanne, Switzerland in 1988 by
Brian O'Regan and Michael Graetzel. Their paper 'A low-cost,
high-efficiency solar cell based on dye-sensitized colloidal TiO2 films'
published in 1991 in the journal, Nature, was the catalyst that spawned a
whole new industry and a whole new way of looking at harvesting electrical
power from sunlight. Since that time Professor Graetzel, now at
Switzerland'sÉcole Polytechnique Fédérale de Lausanne (EPFL), has remained
strongly focused on DSC technology, received numerous awards and accolades
in relation to the invention of DSC, and maintained close links to Dyesol
as Chairman of Dyesol's Technical Advisory Board.
About Dyesol Limited
Dyesol is a global supplier of Dye Solar Cell (DSC) materials, technology

About Dye Solar Cell Technology
DSC technology can best be described as 'artificial photosynthesis' using a
layer of nano-titania (a pigment used in white paints and tooth paste) and
light harvester deposited on glass, metal or polymer substrates. Light
striking the harvester excites electrons which are absorbed by the titania
to become an electric current. Compared to conventional silicon based
photovoltaic technology, Dyesol's technology has lower cost and embodied
energy in manufacture, it produces electricity more efficiently even in low
light conditions and can be directly incorporated into buildings by
replacing conventional glass panels or metal sheets rather than taking up
roof or extra land area.
