Fabrication of low-cost and flexible perovskite solar cells by slot-die coating for indoor applications

Cristina Teixeira, Rosinda Fuentes-Pineda, Luísa Andrade, Adélio Mendes and Dávid Forgács

Cristina’s research goal is to advance the lab-to-fab transition of perovskite solar cells (PSCs). During her PhD (2018-2023) at the company SAULE Technologies (Poland), in collaboration with the University of Porto (Portugal), she helped launch the world’s first pilot line for PSCs and achieved a world-record 25.4% efficiency for a flexible PSC with a graphitic back-contact under indoor lighting. In 2024, she won an MSCA postdoc fellowship and continues her work at CENIMAT|i3N at NOVA University of Lisbon. She holds one patent, three trade secrets, and five high-impact articles as 1st author.

David’s career started at Fraunhofer-ISE during his Master’s, where he researched organic photovoltaics. After authoring some high-impact research articles during his PhD in Valencia and getting hands-on experience on upscaling techniques at Opvius, he joined Saule – a back then 15 people start-up – to commercialize printed perovskite photovoltaics. He was leading the intellectual property and the indoor PV business development at the company. In early 2024 he started Nexunite Ltd. as the CEO and founder, helping to secure European grant funding for research entities, start-ups and SMEs.

What aspect of your work are you most excited about at the moment?

Dávid Forgács: Indoor PV has a huge potential yet to be unlocked. It’s also exciting, as many aspects to consider are different from traditional PV, making the topic rather unique.

How do you feel about Materials Advances as a place to publish research on this topic?

Dávid Forgács: The experience has been great so far, and it seems the audience is adequate for our research

Can you share one piece of career-related advice for early career scientists?

Dávid Forgács: Make sure you research and understand the IP policy of the institution you are working for, and that you have a basic understanding of patenting. One successful application may set you up for life, and bring a lot of opportunities.
