Prof. Paola Vivo
Professor of Material Chemistry, specifically Solar Driven Chemistry
I believe in the enormous potential of solar energy to solve some of the biggest challenges of our times, i.e. climate change and the rapid decrease in energy resources. I want to contribute to the world research on the next-generation solar cells by exploring novel materials and device architectures for efficient, stable, and nontoxic photovoltaics. Our research at the Hybrid Solar Cells team (HSC) aims at developing low-cost and eco-friendly materials in bulk and nanocrystals for photovoltaic applications. In particular, we design and synthesize solution-processable organic semiconductors and hybrid organic-inorganic halide perovskites. Finally, we optimize materials and device architectures to enable high-performing and stable solar cells with reduced toxicity.

I am a postdoctoral researcher working on perovskite solar cells, focusing on passivation molecules, charge transport layers, and device fabrication and characterization. I received my Ph.D. in Chemistry from Yildiz Technical University (TR) in 2023, where my dissertation focused on enhancing the efficiency and stability of lead-based perovskite solar cells through organic interlayer materials. Currently, my research aims to advance both perovskite solar cells and indoor photovoltaics by using passivation molecules to reduce defect states and improve charge carrier dynamics, resulting in higher efficiency and enhanced stability of these devices.
Research interests: Perovskite solar cells, indoor photovoltaics, organic chemistry, organic charge transfer materials.
Skills: Solar cell fabrication and characterization, organic synthesis
Other interests: Painting, traveling, history.

I joined Tampere University having been awarded a research fellowship by the Tampere Institute for Advanced Study as the first step in establishing an independent research direction. My current research project carries the title: “Controlling the Photostability of Next Generation Solar Cells”, where the objective is to understand fundamental photochemical processes leading to photodegradation of light-absorbing materials in next-generation solar cell technologies (dye-sensitised solar cells, organic photovoltaics and perovskite solar cells).
Research interests: physical chemistry, molecular photophysics, photochemistry, optical spectroscopy, organic dyes, microscopy, bio-imaging, solar cells, solar fuels, photodegradation/photostabilisation.
Skills: Absorption/fluorescence spectroscopy, time-resolved optical spectroscopy including time-correlated single photon counting, laser flash photolysis and ultrafast transient absorption spectroscopy, atomic force microscopy, gas/liquid chromatography, mass spectrometry, electrochemistry.
Other interests: Theatre, music and various mechanical projects
