Ana Cristina Ornelas Teixeira

Advanced Functional Materials for Micro and Nanotechnologies
Junior Researcher
Material Scientist @ SAULE Technologies, Poland


Cristina received her PhD degree in Chemical Engineering in the Faculty of Engineering of the University of Porto (FEUP). She developed her MSc thesis and 1st year of her PhD at the research unit LEPABE (at FEUP), and the following years of PhD were developed at the Polish company SAULE Technologies. This company develops perovskite solar devices and is pioneering the market deployment of this technology.

Her research focuses on the development of industrially relevant perovskite solar cells (PSC) and modules, aiming to contribute for its transition from Lab To Fab. It includes carbon-based back-contacts, high efficient and flexible PSCs for indoor applications, and scale-up of low-cost PSC structures using slot-die coating technique.

She co-invented a patent, created 3 trade secrets, published 5 articles as 1st author, and participated in 11 international congresses (won 2 prizes for best presentation).


Besides researching perovskites, Cristina also plays several musical instruments, plays volleyball, and volunteers in an eco-humanitarian movement.
