Photovoltaics

The recruitment of energy sources is becoming a worldwide strategic problem, because of the rapid depletion of fossil fuels from one hand, and the need of eco-compatible solutions to face the global warming on the other hand. Sunlight is arguably the most abundant clean source of energy that is capable of enabling indefinite and sustainable economic growth, with minimum detrimental impact on the environment. The aim of our institute is to furnish a step forward in the development of green photovoltaic technology for abundant and sustainable energy production.
This objective is pursued though a multidisciplinary approach, involving different material preparation and device configuration, photo- physical and electrical characterizations.

 

Hybrid Perovskite Solar Cells

Motivated by the recent results of hybrid organic/inorganic perovskite based solar cells which boost the efficiency of solid state dye sensitized solar cells, we aim exploiting the peculiar properties of such materials. We will study new preparation methods, materials and we will indagate the role that plasmonic materials ( nanoparticles, hyperbolic materials) can play to increase efficiency and stability.

 

2D & 3D Colloidal Nanocrystal based Photovoltaic Devices

We explore novel approaches towards the integration of both two dimensional transition metal dichalcogenide (2D-MDC) and three dimensional colloidal nanocrystals as highly absorbing and solution processable materials for photovoltaic applications.

 

Tailored Nanostructures for Mesoscopic Solar Cells

We work on the design and development of novel electrodes nanostructures using colloidal nanocrystals as building blocks in order to boost the light-to electricity conversion efficiency of the devices.

 

Chromogenic devices

The experimental strategies are devoted to the use of highly performing /innovative materials to be successfully exploited in the design of novel architectures for solid-state devices, with the aim to pave the way towards the industrial exploitation of our experimental results.

 

Bulk Heterojunction Solar Cells

The well known architecture of this class of solar cells will be exploited in order to test new materials and methods to boost the efficiency and increase the air stability to make the cells optimized to be used in real applications.

 

III-V’s Quantum Dots-based Intermediate band solar cells

IBSCs are currently subject of intense theoretical and experimental debate due to the expected possibility of enhancing power conversion efficiency well above the ideal Schockley-Queisser thermodynamic limit. Self assembled Quantum Dots, epitaxially grown within the III-V’s semiconductor family, provide wide flexibility towards the engineering of the operating bands of these devices for the practical demonstration of this concept.

 

Integration of graphene-based materials into PV devices

Research focuses on exploiting the potential that graphene and 2D-related materials offer in improving overall performance of photovoltaic devices. We study: (i) the graphene as a transparent electrode replacing ITO in inorganic (Si-based PN and Schottky junctions) and organic solar cells; (ii) the possibility of incorporating 2D-materials as active layers, interfacial layers and electron acceptors

Alessandro Polini, si aggiudica l'LushPrize2018

Berlino, 16 novembre 2018 

Alessandro Polini , giovane ricercatore presso l’Istituto di Nanotecnologia del Consiglio nazionale delle ricerche (Cnr-Nanotec) di Lecce, si è aggiudicato il Lush Prize 2018 categoria 'Giovani ricercatori', il premio che incoraggia le idee che promuovono la sperimentazione non animale.

Il giovane salentino ha visto così gratificare il suo studio basato sull’utilizzo di modelli 'organ-on-a-chip' altamente sofisticati per capire i meccanismi patologici alla base della Sclerosi Laterale Amiotrofica (SLA). Formatosi nel campo delle biotecnologie mediche, bioingegneria e nanotecnologie, anche con importanti esperienze internazionali -dal Lawrence Berkeley National Laboratory in California all'Harvard Medical School in Massachusetts per approdare poi alla Radboud University in Olanda- Alessandro Polini è rientrato in Italia per proseguire gli studi relativi ai sistemi 'organ-on-a-chip' grazie alla piattaforma tecnologica TecnoMED, il 'Tecnopolo di nanotecnologia e fotonica per la medicina di precisione' nato presso il Cnr-Nanotec di Lecce da un progetto finanziato da Regione Puglia, Cnr e Miur...
