GreatCell Solar, formerly known as Dyesol, was an Australia-headquartered renewable energy supplier and leader in Perovskite Solar Cell (PSC) technology. In 2018 the company went bankrupt.
Following the company's liquidation in 2018, Greatcell Solar Materials was spun-off to a separate entity. In addition, GreatCell's Solar equipment, IP and subsidiary in Italy were acquired by a newly formed company called Greatcell Energy.
GreatCell manufactured and supplied PSC materials and was dedicated to the successful commercialization of PSC photovoltaics. It is mainly focused on:
- Developing (and continuously advancing) a suite of thoroughly tested PSC chemicals, components and equipment used in the manufacture of PSC cells, modules and panels to researchers and industrialists;
- Providing turn-key and custom fabrication facilities for research, development and production of PSC photovoltaic devices; and
- Providing specialist training, consulting and engineering solutions for the application of PSC photovoltaic technology
One of GreatCell's main activities was the development and supply of photoactive materials, mostly for R&D. The company started offering perovskite materials around 2013.
GreatCell's main goal, however, was to develop perovksite-based solar panels. One example was the company's intensive research into steel substrates for solar panels. GreatCell was working on flexible steel-integrated panels (as part of SOLLIANCE) which had the potential to find a huge market in the warehouses and industrial buildings across Europe. In addition, GreatCell developed glass-based perovskite. The company aimed to establish Joint Ventures with solar panel makers for the creation of commercial production lines.

The latest GreatCell news:
Australia-based Dyesol has announced the signing of a letter of intent (LOI) to collaborate with the Commonwealth Scientific and Industrial Research Organisation (CSIRO) in the development of perovskite solar cells (PSC).
The LOI creates a non-binding framework for collaboration and coordination between the two organizations. The collaboration aims to be a step towards the development of commercially viable PSC technology. CSIRO is currently the 4th largest shareholder in Dyesol. The two have worked together in the past, collaborating in 2010 on materials for dye sensitized solar cells. Since then, Dyesol has shifted to focus on PSC development.
Dyesol recently secured a Â£800,000 ($1.05 million) grant by the U.K.'s Engineering and Physical Sciences Research Council (EPSRC) for the continued research in the optimization of charge carrier mobility in nanoporous metal oxide films and will enable the Australian organic cell developer to better understand the impact of halide modified titania on Perovskite cell performance.
The EPSRC is the U.K.'s main agency for funding research in engineering and the physical sciences, and this grant will be delivered specifically to Dyesol UK, Cristal and the University of York. The grant monies will, Dyesol said, help support better understanding of the chemistry of the improved electron capture and transport technique.
Dyesol's UK branch has joined the GOTsolar project, part of the Horizon 2020 program. GOTsolar is a new project which started in January 2106, and Dyesol will be cooperating with partners in Portugal, Switzerland and Poland, as one of seven members of the GOTSolar consortium.
High efficiency perovskite-based solar devices will be fabricated and hermetically encapsulated using a new laser-assisted encapsulation process to enable high durability. These devices will be tested under accelerated aging conditions to validate the new process and to demonstrate the scalability of technologies developed as part of the project. This, according to the company, forms a key aspect of Dyesol's roadmap for metal based flexible modules with 20 years of lifetime.
Dyesol, global leader in the development and commercialization of Perovskite Solar Cells (PSC), has announced that it has appointed VDL Enabling Technologies Group to assist in the development of a Major Area Demonstration Prototype.
The 1st Phase contract involves a specialist engineering study resulting in the preparation of a Feasibility & Functional Specification for Perovskite Major Area Demonstrator development. This phase will be conducted over a 4 month period commencing immediately. It is expected that upon the successful completion of the initial study, a 2nd Phase of design and development will follow, and the 3rd Phase will be Realization. The 3 phase project is expected to be completed in the 1st half of 2017.
In November 2015, Dyesol announced its plan to raise up to AUD 10 million (USD 7.25 million/EUR 6.8 million) by selling shares to shareholders and investors. Now, the company announce that it has successfully completed a capital raising of $8.1 million ($5.85 million USD).
Dyesol, the Australia-based renewable energy supplier and leader in Perovskite Solar Cell technology, announced that a research team at the Ecole Polytechnique FÃ©dÃ©rale de Lausanne (EPFL) has established a remarkable efficiency for its Perovskite Solar Cells (PSC), with a conversion efficiency of 21.02%.
This conversion efficiency was certified at the laboratories of Newport Corporation in Bozeman, Montana USA. This new conversion efficiency eclipses the previous record of 20.1%.
Dyesol, the Australia-based Perovskite Solar Cell (PSC) technology developer, aims to raise up to AUD 10 million (USD 7.25 million/EUR 6.8 million) by selling shares to shareholders and investors.
A share purchase plan (SPP) opened on November 19, allowing existing shareholders from Australia or New Zealand to subscribe to new shares priced at AUD 0.26 a piece. The SPP targets AUD 6 million in proceeds, to support Dyesol's Technology Development and Business Activity plans and working capital. The SPP is expected to close on December 4.
Australia-based Dyesol has been awarded a $449,000 grant from the Australian Renewable Energy Agency (ARENA) to commercialize an innovative, very high efficiency perovskite solar cell.
ARENA has stated that the funding would enable Dyesol to create a roadmap setting out the steps needed to take its perovskite solar cell technology from the lab to a commercially available product. Dyesol will map out the techniques and requirements for working towards scalable manufacturing of high-quality, uniform perovskite cells that achieve efficiency, durability and stability targets.
Australia-based organic PV and perovskite solar cell (PSC) developer Dyesol declares a major breakthrough in perovskite stability for solar applications. Stability and durability were among the biggest challenges with which perovskite PVs were faced in recent years, with the material sensitive to moisture contact and high efficiency perovskite cells exhibiting high degradation rates.
Now, Dyesol claims to have made a significant breakthrough on small perovskite solar cells, with 'meaningful numbers' of 10% efficient strip cells exhibiting less than 10% relative degradation when exposed to continuous light soaking for over 1000 hours. The cells were encapsulated and tested at full sun intensity for this duration and exhibited relatively low degradation levels, according to the company. Dyesol has not exposed what form of encapsulation was used for the cells tested (as both flexible and traditional glass encapsulation are suitable for PSC applications).
