GreatCell Solar
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.

UtmoLight's 6.7 MW perovskite rooftop project connects to the grid, among the largest of its kind
UtmoLight's 6.7 MW perovskite rooftop distributed PV project at Wanshan Lake Park was connected to the grid and put into operation on July 31, completing the project first announced in partnership with Wuxi Xingyuan Green Energy back in November 2025.
The project uses the roof resources of factory buildings in the park, with nearly 15,000 pieces of UtmoLight's own 2.81 m² perovskite PV modules installed. It operates under a "self-generation for self-use, with surplus power fed to the grid" model.
Halocell to start producing indoor perovskite PVs that can replace disposable batteries and charger cables
Australian start-up Halocell will reportedly begin producing flexible 7 centimeter-long photovoltaic strips that are said to generate enough power to replace the pair of disposable batteries in a TV remote, or the charger cable for a set of headphones. This represents the first large-scale manufacturing in Australia of perovskite PV technology.

The Halocell modules will each cost less than a dollar to make and the Company has ambitious plans to produce millions per year, its CEO Paul Moonie said.
Greatcell Solar announces bankruptcy
The Directors of Greatcell Solar have sadly announced that a decision was taken to appoint administrators to the Greatcell Solar group of companies following sustained, but ultimately unsuccessful, attempts to secure re-financing for its activities.
Greatcell Solar Limited, Greatcell Solar Industries and Greatcell Solar Australia were placed into voluntary administration. The decision follows a series of unfortunate and unwelcome developments in recent weeks, including the untimely death of Chief Scientist, Dr Hans Desilvestro in a mountaineering accident on 10 November.
