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

Loretta del Mercato, si aggiudica l'ERC STARTING GRANT 2017

Loretta del Mercato, si aggiudica  l'ERC STARTING GRANT 2017

uno dei bandi più competitivi a livello europeo.

Lecce, 6 settembre 2017 

Lo European Research Council, che promuove la ricerca di eccellenza in Europa, nei giorni scorsi ha reso noti i nomi dei 406 vincitori della selezione ERC STARTING GRANT 2017, il bando tra i più competitivi a livello internazionale.

Su 3085 progetti presentati, 406 i progetti selezionati a cui sono stati destinati i 605 i milioni di euro di investimento. 48 le nazioni di provenienza dei ricercatori, soltanto 17 gli Italiani che condurranno le loro ricerche nel nostro paese, tra cui Loretta del Mercato, ricercatrice dell'Istituto di Nanotecnologia del Consiglio Nazionale delle Ricerche di Lecce.

Un importante riconoscimento alla ricerca nel settore della medicina di precisione condotta presso il CNR NANOTEC, un indiscusso premio al talento della giovane ricercatrice che, a 38 anni e un contratto a tempo determinato, sarà a capo del progetto "Sensing cell-cell interaction heterogeneity in 3D tumor models: towards precision medicine – INTERCELLMED".

Il progetto, il cui obiettivo è affrontare uno dei problemi più spinosi della ricerca sul cancro, ovvero la difficoltà nel trasformare i risultati delle ricerche scientifiche in applicazioni cliniche per i pazienti e che vedrà coinvolto l'Istituto tumori "Giovanni Paolo II" di Bari, si propone di sviluppare nuovi modelli in vitro 3D di tumore del pancreas, alternativi ai modelli animali, ingegnerizzati con un set di sensori nanotecnologici che consentiranno di monitorare le interazioni delle cellule tumorali con il loro micorambiente, verificare l'appropriatezza delle terapie prima della somministrazione ai pazienti oncologici e quindi prevedere la risposta dei singoli pazienti ad una o più terapie antitumorali.

La realizzazione di queste piattaforme 3D multifunzionali consentirà di superare le evidenti differenze intercorrenti tra "modelli animali" ed esseri umani fornendo dati attendibili ed in tempi più rapidi rispetto ai dati ottenuti tramite lunghi e costosi procedimenti di sperimentazione sugli animali. Le tecnologie e i modelli sviluppati saranno estesi anche ad altre forme di tumori solidi nonché impiegati per studi nell'ambito della ingegneria tissutale e della medicina rigenerativa.
