Dyesol is a solar energy company developing 3rd generation solid-state Dye Solar Cell technology known as Perovskite Dye Solar Cell into the building envelope. 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 , 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 , Greatcell Solar S.A. , and Switzerland's École Polytechnique Fédérale de Lausanne . It was listed on the Australian Stock Exchange in 2005 and the German Open Market , and is trading on the OTCQX through its depositary BNY Mellon.In May 2013 Dyesol announced that Dye Solar Cell technology has achieved a technical breakthrough by achieving a solid-state 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 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 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".

It is believed that solid-state perovskite solar cells (PSCs) will be the next generation of power source, contributing for fostering the use of photovoltaics in buildings roofs and facades. Actually, their transparency, various possibilities of colors and high kWh/nominal power ratio offer to PSCs an opportunity to conquer markets that are not attainable by traditional silicon solar cells. To turn this ambition to a marketable product several efforts are still needed and this project aims to give relevant answers to those key challenges. GOTSolar proposes disruptive approaches for the development of highly efficient, long-lasting and environmentally safe PSCs. Metal oxide scaffolds employing perovskites and pigment materials with extraordinary high-efficient light harvesters in conjunction with solid-state HTMs will be developed and assembled together. The obtained materials will be characterized to elucidate the interplay of the mesostructure, the perovskite absorber and the HTM layer. These measurements will be used to understand the circumstances electron and/or hole collection is favourable allowing the optimization of the whole device. This understanding and the developed materials will provide the tools to push the PV performance towards 24 % efficiency for lab-size (ca. 25 mm2) and stable for 500 h under 80 C. In parallel, lead-free light absorbers will be developed aiming a power conversion efficiency of 16 %, also in lab-size cells. These high-efficient devices will be encapsulated using a new hermetically laser assisted glass encapsulation process to enable high-durability and tested under accelerated aging conditions. Following, a device of 10 10 cm2 will be built and used for demonstrating the scalability of the developments for producing the first perovskite solar module with potential for 20 years of lifetime.

The DESTINY initial training network will tackle major challenges in the development of stable dye-sensitized solar cells, DSC. DSC offer exciting possibilities for applications in building integrated photovoltaics and consumer electronics. However they possess a complex structure with disparate materials. For DSC to be marketable and to compete with its inorganic counterparts, fundamental science has to be done to understand the causes of degradation and find ways of enhancing cell and module life time and stability without sacrificing performance and scalability. Ten internationally leading European research groups from six countries [including Dyesol UK, part of Europes leading industrial supplier of DSC] have joined forces as full participants with a commercial associated partner, combining expertise in synthetic chemistry, spectroscopy, nanoscale physics and device engineering. Our highly integrated approach to understanding degradation causes and proposing solutions will take a major step towards the commercialization of DSC. This consortium is strongly committed to promote breakthroughs at the frontiers of science and engineering. The training dimension of DESTINY is reflected in the high priority we give to the training of early stage and experienced researchers, ESRs and ERs, through education and knowledge dissemination via Tutorial Courses, Annual Network Meetings, Training Schools, Conferences and Mobility Programmes. The network, with a strong focus on interdisciplinary training, builds on fruitful collaborations between the partners. Development of complementary skills (presentation, management, technology transfer, IP protection) will take place throughout the project lifetime. Interaction with stakeholders beyond those involved primarily in research will be maintained to enhance the international and societal dimension of our research and provide the wider community with information on this new technology.

Widespread uptake of inorganic semiconductor solar cells has been limited, with current solar cell arrays only producing between 4 to 7 GW of the 15 TW (<0.04%) global energy demand, despite the terrestrial solar resource being 120,000 TW. The industry is growing at a cumulative rate of over 40% per annum, even with effects of the financial crisis. The challenge facing the photovoltaic industry is cost effectiveness through much lower embodied energy. Plastic electronics and solution-processable inorganic semiconductors can revolutionise this industry due to their relatively easy and low cost processability (low embodied energy). The efficiency of solar cells fabricated from these cheap materials, is approaching competitive values, with comparison tests showing better performance for excitonic solar cells with reference to amorphous silicon in typical Northern European conditions. A 50% increase of the output will make these new solar cells commercially dominant in all markets since they are superior in capturing photons in non-ideal conditions (angled sun, cloud, haze) having a stable maximum power point over the full range of light intensity. Our objectives are to exploit the joint leadership of the top European and Indian academic and industrial Institutions to foster the wide-spread uptake of Dye-Sensitized Solar Cells technology, by improving over the current state of the art by innovative materials and processes. The Indian project will tentatively start within six months after the start of the European project.
