Greatcell Energy
the Heritage of our Company

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.
