Solar Ltd, the UK-based hydrogen production research
and development company today (August 4) announced
it has more than doubled the performance of its world
leading Tandem Cell™ technology, and is moving towards
the 10 percent benchmark accepted for commercial production.
increase means that the Tandem Cell™ is now able to
directly convert more than 8 percent of sunlight energy
directly into pure hydrogen fuel.
target 10 percent performance level was recognised
in 2003 by the industry as the common benchmark for
commercially viable production on the open energy
to the increases in performance is the use of nano-crystalline
coatings within the exclusively-licensed Tandem Cell™.
Using novel metal-oxides, the coatings produce high
photocurrent densities, and create a highly efficient
means of converting light and water into hydrogen
fuel from one single unit.
low-cost, scalable, materials Hydrogen Solar began
work on the nano-crystralline coatings in mid 2002,
and CEO Dr David Auty believes further increases in
the conversion rate can be expected.
now have a scalable pathway, and can confidently foresee
higher performance levels in the near future,"
Solar Ltd expects its world-leading technology will
be used as a clean, CO2-free fuel for transport and
home energy installations.
means, for example, that at the benchmark 10% performance
level, a 7m x7m Tandem Cell™ unit on a double garage
roof is capable of producing enough hydrogen from
sunlight to run a Mercedes A-Class vehicle 11,000
miles over a year in Los Angeles light conditions,"
Dr Auty said.
Tandem Cell™ is also expected to be incorporated into
building designs, particularly on factory and garage
