Energy independent office projects are now going live thanks to perovskite technology, which is ready to be integrated into building façades. Skanska will apply the test cells onto its projects in 2018, creating a significant milestone towards zero-energy and carbon neutral office investments.
The developer has exclusive rights to use Saule Technologies’ solar cell solutions, as stated in a license-based agreement signed between the two companies, in building façades and noise barriers across all Skanska markets worldwide (the Nordics, Europe and the USA). Perovskite technology means benefits for the developer, tenants and communities – favorable implementation costs, lower energy costs and consumption, and lower carbon footprints.
Perovskites are crystalline materials that have great potential to replace silicon - currently the world’s most popular semiconductor in solar cell applications. Saule Technologieshas been working on the application of inkjet printing for fabricating free-form perovskite solar modules since 2014. This technique allows the shapes and areas covered by each layer to be customized according to requirements. The stability and water resistance of the modules makes them ideal for the construction industry.
With a Japanese investor on board, along with support from the Polish National Centre for Research and Development and several research grants worth more than EUR 20 million, Saule Technologies is now working on a large-scale, prototype production line.
“Perovskite solar cells offer new opportunities to architects and construction companies willing to utilize solar power. Our modules are lighter, thinner and much more design friendly than the most popular silicon solar cells. We may customize the shape, color and size of the module depending on the needs of the customer and install them wherever there is a free area on the building. This also means not being limited to the roof,” said Olga Malinkiewicz, co-founder and CTO at Saule Technologies.
