Saule Technologies: one step closer to commercializing perovskite technology

Saule Technologies is an enterprise aiming to develop and commercialize flexible photovoltaic cells based on perovskites. The company may be young, with just about a year of track record, but it is good and ready to show their first prototype. Today, at the International Conference on Perovskite Thin Film Photovoltaics (ABXPV) in Barcelona, the Saule team presented a small, flexible module, which can be easily incorporated into a smartphone. The demonstration device, when exposed to light, provides enough power to charge up a phone battery.

Olga Malinkiewicz, Saule Technologies co-founder and CTO, recipient of the European Commission award Photonics21, and MIT Technology Review’s Innovator of the Year: ‘This is a special moment for all our team. We have reached that phase when we can finally show the results of our work. The prototype presented today – small, flexible, perovskite module – is just the beginning. With subsidies we have received from the National Centre for Research and Development (NCBR) and contribution made by a Japanese investor, we can now boost the efficiency of the module and further refine the technology in our own, well-equipped lab.’ Malinkiewicz gives a technical glimpse into these future developments: ‘The challenge now is to integrate each, separate process into one production line. For that we use ink-jet printing as it is a rather straightforward way to do it.’


The company’s special role at ABXPV stems from its outstanding achievements in implementing ink-jet production methods in manufacturing flexible photovoltaic cells. Piotr Krych, CEO at Saule: ‘This is the first example of perovskite technology being used in a portable electronic device. With the recent financial support, we will be able to develop methods for mass production, to print ever larger and more efficient photovoltaic cells. The progress we are making attracts a lot of attention from a wide range of businesses worldwide, including the biggest global brands.’


Artur Kupczunas, Saule co-CEO gives an insight into the company’s operations: ‘What we do is not typical scientific work. So, while our lab team is doing their job in Wrocław, the business people conduct vigorous negotiations with our potential partners. We work in synergy – this way we can achieve our goals and we can do this significantly faster. The prototype presented today is certainly an important signal to the market that the era of perovskites is coming.’


Saule team consistently strives to attain its goals and is set to demonstrate the possibilities offered by the technology – both in industrial applications and everyday life. By sharing their knowledge and the results of their work, they prove that such innovations are necessary and lay the grounds for integration of science with business, in Poland or elsewhere in the world.
