Greatcell Energy Limited (GEL) was founded in 2019 to be a major force in the innovation of Perovskite Solar Cells (PSC). The Company is involved in the development, scale-up and commercialisation of PSC with particular emphasis on the massive and rapidly growing markets for micropower, including IoT and rechargeables. The Company has not abandoned the more well known market place of grid solar but it recognises that the challenges of competing with silicon will be better served when the PSC technology is more advanced, whereas the current maturity of PSC is amply sufficient to service the micropower market.
In the rapidly emerging field of 3rd generation solar photovoltaic (PV) technologies, PSC is the 'daughter' of Dye Solar Cells (DSC), a technology invented by Grätzel and O'Regan at the École Polytechnique Fédérale de Lausanne in 1989. The 3 rd generation technologies all have the advantage of lower embodied energy, meaning that the cells would be cheaper to produce, and they outperform traditional solar in variable and low light conditions. PSC has the additional advantage of a high cell voltage and better spectral absorption coverage. Being a thin film technology it can be produced as a low weight panel and will find application on buildings (BAPV) and as part of the building structure (BIPV). It is the most truly disruptive solar technology of all time.
Greatcell Energy has an exceptional IP portfolio on which to industrialise our products. The Company is building on a legacy of over 20 years R&D in 3 rd generation solar, starting with development of DSC and progressing to PSC in 2013. The technology was developed by Greatcell Solar (Dyesol) group and has been acquired exclusively by Greatcell Energy since the commercial demise of Greatcell Solar. As well as the extensive IP portfolio, Greatcell Energy acquired the necessary equipments to establish a pilot plant for micropower and low power devices. Through our Italian subsidiary we are engaged in several funded European projects and the development and sale of specialist equipment with particular emphasis on unique solar module testing. In Europe, the Company has revitalised its sales efforts for specialty materials.
In 2013, DSC made an irreversible leap forward with the advent of a solid-state material set. For a short while this was described as solid-state DSC, but has subsequently emerged as PSC because it is based on a generic class of photoactive compounds known as perovskites. In many respects this is an evolution and combines the best elements of both DSC and OPV to provide a genuinely disruptive, new PV technology. The timing is undoubtedly auspicious given the co-ordinated climate and energy policy agreements of Copenhagen (2009) and Paris (2015) driving the renewable energy agenda.
The industrialisation basis for the Company to move forward today comes from a number of major projects over the years developing glass based products in USA, Australia and Korea and R2R steel sheet and polymeric substrate products in UK and Europe. This background has enabled the Company to establish a number of potentially strong MOU's with companies in the IoT and rechargeable market places.
The Company is led by highly experienced business and technological people including the founders of Dyesol who have returned to complete the task they initiated in 2005 of delivering 3 rd Generation Solar technology to the mature renewable energy market place.
