Dyesol: Titanium Solar Cell

Dyesol announced their 'float' and IPO on the Australian Stock Exchange (ASX) this week. Much to my enjoyment, Dyesol has taken my advice and created a biomimic of photosynthesis. Although not exactly the way I had envisioned, but then again they have been working on titanium dioxide based solar cells for a decade. The titanium dioxide is cheaper and cleaner to manufacture then traditional silicon solar cells. And while their unique dye seems expensive to me, the technology is poised to help revolutionize solar energy (I know I've said this about others, but it's a rapidly growing field...)Dyesol technology mimics the biology of plants. Plants (according to Dyesol) aren't extremely efficient at converting all light to energy, but are effective at capturing energy over a wide range of light conditions. This was the inspiration that set them apart. The use of a dye system enables the technology to work in lower light levels then traditional PV. The construction of the cell is pretty straight forward- and nicely summarized by dyesol:"In basic realization a Dye Solar Cell comprises a layer of nano-particulate titania (TiO 2) formed on a transparent electrically conducting substrate and photosensitized by a monolayer of dye. An electrolyte, based on an Iodine - Tri-iodide redox system is placed between the layer of photosensitized titania and a second electrically conducting catalytic substrate."

Dyesol hopes to be a leader in the third generation of solar cells, and is expecting to work with major manufacturing companies to further develop and enhance this groundbreaking technology. By using inexpensive and ecologically friendly materials, Dyesol moves forward with a light touch.::Dyesol
