GreatCell Solar Limited (ASX: GSL) previously known as Dyesol, is a solar energy company developing perovskite solar cell 3rd generation thin-film solar cell technologies and materials. The company was previously focused on developing solid-state dye-sensitized solar cell (DSC or DSSC) technology but now focuses on perovskite chemicals, components and equipment, and assists manufacturing partners to produce perovskite photovoltaic modules. The company is based in Queanbeyan, Australia and opened its manufacturing and research facilities in October 2008. It has expanded to several locations around the world, including the UK and Switzerland, and has established joint ventures in South Korea, Germany, Singapore and more.

The company was predominantly focused on perovskite solar cell and materials development, with numerous academic and corporate partnerships trying to commercialise modules based on both glass and metal substrates by 2019 and 2020 respectively.[1] In July 2017, a memorandum of understanding was signed with the world's largest solar panel manufacturer Jinko Solar which is hoped to lead to large scale deployment of the technology.[2]. In October 2018, the Production Division of Greatcell Solar was spun off, in a new business called Greatcell Solar Materials (GSM).[3]

In December 2018, GreatCell Solar Limited entered administration [4] and was put in liquidation in September 2019.[5]

Greatcell Solar Materials still operates as a manufacturer of materials for renewable energy systems applications including the photovoltaics research sector and the electronics industry.[6]

DSC development and company history

Dye-sensitized solar cell technology was invented at the Institute of Physical Chemistry, 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, spawned a new research field and a new route to harvest electrical power from sunlight. Since that time Michael Grätzel, now at Switzerland's École Polytechnique Fédérale de Lausanne (EPFL), has received numerous awards and accolades in relation to the invention of DSCs, and maintained close links to Dyesol as Chairman of Dyesol's Technical Advisory Board.

Major differences between DSC & ssDSC

From 1994, STI and Greatcell teams in Australia and Switzerland 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 large portfolio of patents. Dyesol further acquired STI in 2006 and Greatcell in 2007.

Dyesol Limited was formed in 2004 to accelerate the commercial development of DSC 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.

Transparent Tandem DSC on Glass

In May 2013 Dyesol announced that Dye-sensitized Solar Cell (DSC) technology has achieved a technical breakthrough by achieving a solid-state DSC (ss-DSC) efficiency of 11.3% at full sun. The technology is particularly important in solar markets where light conditions are sub-optimal, such as Europe, North America and North-East Asia, or low-light conditions (such as indoor applications) where much higher efficiencies over 30% can be achieved.

Solid State DSC efficiency against Liquid DSC

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%".[7] However, this is now considered a perovskite solar cell and the official accredited DSC solar cell efficiency is 11.9% determined by the National Renewable Energy Laboratory.[8] This efficiency is not expected to greatly increase as the DSC field has largely shifted to the development of perovskite solar cells which have achieved certified efficiencies over 23%.[9]
