Organic and Hybrid Materials and Devices for Photovoltaics, Artificial Photosynthesis and Optoelectronics

Alessandro Abbotto

Organic and Hybrid 3rd Generation Photovoltaics

Our group studies organic and organometallic materials and devices for third generation photovoltaics, including dye-sensitized solar cells (DSSC) and organic/polymeric solar cells. Our work, in collaboration with national and international partners, focuses on the synthesis of new photosensitizers, electrolytes, hole conductors, and TiO2 films with tailored properties and optimized performances.

Our group is also involved in the design and synthesis of low-bandgap polymers and molecules for optimal light harvesting and charge generation and transport in low-cost organic photovoltaic devices. Main design strategy is based on the use of donor-acceptor (hetero) aromatic components for fine tuning of optical and electronic properties. DSC and organic photovoltaic cells and modules are prepared and fully characterized in the MIB-SOLAR Solar Energy Centre of the Department (ISO 7 clean room), in collaboration with leading companies.

Artificial photosynthesis: cleand and renewables solar fuels

This recent activity includes materials (photosensitizers, catalysts, etc.) and devices (solar fuel generation cells) for artificial photosynthesis, namely production of hydrogen and oxygen from water (water splitting) as clean and renewable solar fuels. Focus is on the use of molecular and polymeric materials (including bio-inspired dyes) as new efficient photosensitizers. Devices are investigated in the MIB-SOLAR Solar Energy Centre of the Department.

Organic Materials for Photonics and Optoelectronics

Based on a multiyear experience on the design and synthesis of multipolar aromatic and heteroaromatic chromophores we are currently investigating new molecular and supramolecular organic and hybrid materials for multiphoton absorption, photonic crystals, plasmonics, semiconducting polymers, and sensing of air and water contaminants and explosives.
