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
