Dyesol (, , ) is a solar energy company developing 3rd generation solid-state Dye Solar Cell (DSC) technology known as Perovskite Dye Solar Cell into the building envelope. (Building Integrated Photovoltaics or BIPV) The firm develops DSC chemicals, components and equipment and assists manufacturing partners to produce solar cell modules. It is headquartered in Queanbeyan, Australia and it opened its Manufacturing and Research Facilities on October 2008. It has expanded internationally to strategic locations around the World such as the U.K. and Switzerland as well as joint ventures in South Korea, Germany and Singapore. 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's École 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. From 1994, STI and Greatcell teams in Australia and Switzerland further developed DSC technology and established the world's first DSC prototype manufacturing facility in Australia in 2000. Key to that development phase was the invention of processes, new materials, and equipment to manufacture DSC products. Dyesol acquired the laboratory, manufacturing equipment and intellectual property which has resulted in a portfolio of patents that Dyesol before mid-2005. Dyesol acquired STI in 2006 and Greatcell in 2007. Dyesol Limited was formed in 2004 to accelerate the commercial development of Dye Solar Cell technology and build on the DSC work of previous 14 years carried out by Sustainable Technologies International Pty Ltd ("STI"), Greatcell Solar S.A. ("Greatcell"), and Switzerland's École Polytechnique Fédérale de Lausanne (EPFL). It was listed on the Australian Stock Exchange in 2005 (DYE) and the German Open Market (D5I.F), and is trading on the OTCQX (DYSOY) through its depositary BNY Mellon. In May 2013 Dyesol announced that Dye Solar Cell (DSC) technology has achieved a technical breakthrough by achieving a solid-state DSC (ss-DSC) efficiency of 11.3% at full sun. At this level of module performance the technology will be grid competitive - the "Holy Grail" for renewable energy technologies. This achievement is particularly important in solar markets where Light Conditions are sub-optimal, such as Europe, North America and North-East Asia, where Dyesol ssDSC technology has a considerable advantage over 1st and 2nd generation photovoltaic technologies. Dyesol has been working closely with R&D partner, the EPFL, and is confident of announcing further improvements in solid-state performance in the near term. Remarkably, Perovskite solid-state DSC (ssDSC) performance is confidently expected to outperform all hitherto known and published 1st and 2nd generation Photovoltaic Cells. On July 11, 2013 Dyesol /EPFL announced a new record DSC efficiency. Michael Grätzel stated ”Our research work on solid-state Dye Solar Cells (ss-DSC) is now achieving efficiencies exceeding 15% . Currently, the official accredited World Record Efficiency is 14.1% however efficiencies exceeding 15% are being achieved in the laboratory using perovskites , and experts are forecasting well beyond 20% as achievable not too distantly". == Dye Solar Cell Technology == DSC technology can best be described as 'artificial photosynthesis' using an electrolyte, a layer of titania (a pigment used in white paints and tooth paste) and ruthenium dye deposited on glass, metal or polymer substrates. The term mesoscopic has been introduced to reflect further advances in the technology, particularly where a perovskite is substituted for dye as a sensitiser. Light striking the sensitiser 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. . 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Dyesol」の詳細全文を読む スポンサード リンク
