Pedro has been developing chalcogenide materials such as Cu(In,Ga)Se2 (CIGS) as solar cell absorbers. He has also worked on nanostructured rear passivation layers for high-efficiency ultra-thin CIGS solar cells. Recently, he has been interested in semi-transparent photovoltaics (STPV) and their applications as "Solar Windows" for building Integrated PV (BIPV) and in flexible photovoltaics and their application in textile substrates.

He is currently focused on topics such as Micro-Nanofabrication for Photovoltaic Solar Energy, Semi-transparent Photovoltaics for Window Applications, Photovoltaic cells on textile substrates, and Solid-state thin-film batteries.

Pedro joined the Nanostructured Solar Cells group at the INL—International Iberian Nanotechnology Laboratory (Braga, Portugal) in 2017 after a Ph.D. in Biomedical Engineering from Minho University (Braga, Portugal), comprising a three-year stint as an Invited Researcher at Gracias Lab at the Johns Hopkins University (Baltimore, USA). He is interested in photovoltaic materials, thin films, and micro and nanofabrication and is always eager to combine these three fields, as shown in more than 30 peer-reviewed scientific publications.
