Sydney, Australia. 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 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. – See more at: http://www.dyesol.com/posts/cat/corporate-news/post/new-record-efficiency-for-dye-solar-cells/#sthash.dmKnIGJZ.dpuf
