Saule Technologies is a Polish start-up that designed a low-temperature method for manufacturing flexible photovoltaic perovskite cells. The company is working on the development of a flexible and semi-transparent cell based on PET foil.
In December 2014 in Boston, Saule Technologies unveiled the world's first printed perovskite.
Saule's aim is to combine perovskite solar cells with other currently available products.
In January 2018, Saule announced the signing of a cooperation agreement with Skanska's commercial development business unit in Central Eastern Europe. The construction company will be the first to cover office buildings with semi-transparent perovskite solar cells on a commercial scale. Saule Technologies will be the technology provider. The initial implementation tests are planned for 2018 in Poland.
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).
Saule Technologies has been working on the application of ink-jet 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 make them ideal for the construction industry. The company has conducted advanced research on perovskite applications in solar energy harvesting and optoelectronics with leading international universities in the UK, Israel, Germany, Italy and Spain. 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 working on a large-scale, prototype production line.
