Developing a breakthrough in perovskite solar cell

Saule Technologies is one of the first companies in the world working on the commercialization of perovskites in the new generation of photovoltaic cells. The company has pioneered the application of ink-jet printing for the fabrication of flexible, light-weight, semi-transparent and efficient perovskite solar modules. Currently, Saule Technologies is a team of 35, including 25 scientists from 13 countries working in Wrocław in one of the most advanced optoelectronics laboratories in Europe, to develop the most cost-competitive and versatile solar energy technology to date.

How did you come up with the idea of your business?

It happened during my PhD research at the University of Valencia. I had some alluring idea and done some tests in a laboratory. This way I developed a novel perovskite cell architecture, very promising. Thanks to that invention, for the first time fabrication of the efficient perovskite at low temperatures was enabled – in example, due to this we can print perovskite solar cells directly on clothes, plastic film or paper.

When media found out what happened, there was some positive buzz. My current partners Artur Kupczunas and Piotr Krych read about me and my discovery in newspapers and concluded it’s good business opportunity. They visited me in Valencia, offered their help and this way we decided to start a company: Saule Technologies.

What were the biggest challenges you had to face and how did you manage to overcome them?

Oh, it was a pioneering venture in many ways, almost all obstacles we could describe as „the biggest challenge”! But now we are where we are. We have one of the best laboratories in Europe, we have really great crew – most talented young scientist from around the world – and we are very close to our goal. And we are where we are because we believe in ourselves, we work very hard and never give up. We support each other, all Saule Technology workers are very close to each other, it’s very important to us. We believe there is no good work without true passion, loyalty and focus, and it’s impossible without true friendly atmosphere in a company.

Is the tech market competitive in Poland, how would you describe it?

To be honest, Poland is not one of leading tech markets yet. We need stronger local competition, because now our main rivals are from abroad. I hope it will change soon. We have many talented young persons in Poland, many start-ups are created nowadays. These seeds will grow.

Where do you sell your products and what are your plans for the further growth of Saule Technologies?

We don’t sell our product yet. We still improve it in our laboratory. But we are close. Now we are going to build our first production line in our factory in Poland. Our product should be available on market at the end of next year.

Why do you think Polish women are such great leaders and entrepreneurs?

Probably because we have a very good example to follow. Maria Skłodowska-Curie, pioneering physicist and chemist, became the first person to win two Nobel prizes. She discovered two elements: polonium and radium. Recently Maria Skłodowska-Curie has been named the most influential woman in history in a BBC History magazine list of 100 female trailblazers. I agree she deserved such honor. Maria Skłodowska-Curie is the best possible inspiration to all of us. We try to be like her. We can’t achieve this goal, but at least we can try.
