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

Technology Trasfer in Nanotechnology

Technology Transfer in Nanotechnology: Challenges and Opportunity

Lecce, 18/19 ottobre 2018

CNR NANOTEC c/o Campus Ecotekne

JRC in collaboration with the National Research Council (Cnr) is organising a workshop on Technology Transfer in Nanotechnology,

which will take place in CNR Nanotec (Lecce, Italy) on 18 and 19 October. This workshop is organised in the framework of the TTO-CIRCLE initiatives.   The aim of this event is to explore how technology transfer activities can be used as a mechanism to help EU industry, particularly Start-ups and SMEs, and Government in deploying and adopting Nano-technology. Practical examples will be presented to illustrate the potential of technology transfer in this area.   The workshop will gather technology providers, industry executives, technology transfer officers, policy makers and financial intermediaries to share experiences and lessons learned. One of the key objectives is to discuss policy implications at all levels that could help accelerating the adoption of Nanotechnology by the European manufacturing industry.

Nanotechnology Transfer Day

26 Luglio 2018 - Lecce

CNR NANOTEC c/o Campus Ecotekne Siglato l’accordo lo scorso maggio tra CNR NANOTEC e Pairstech Capital Management, ha preso il via la collaborazione con PhD TT per la valutazione della ricerca

E’partita la collaborazione con PhD TT per la valorizzazione della ricerca sulla base dell’accordo siglato lo scorso Maggio tra CNR NANOTEC e Pairstech Capital Management, società di gestione patrimoniale che fornisce agli investitori istituzionali e privati un insieme di veicoli di investimento, al fine di valorizzare i risultati della ricerca svolta all'interno dell'Istituto.

Giovedì 19 Luglio dalle ore 11 alle ore 14 nella sede del CNR Nanotec di Lecce si è tenuto un incontro sul trasferimento tecnologico nel settore delle nanotecnologie applicate al settore biomedicale.

L’evento è stato organizzato dall’ufficio di Trasferimento Tecnologico del CNR Nanotec che ha inaugurato con questa giornata un ciclo di eventi mirato a presentare agli attori dell’ecosistema dell’innovazione nel settore delle nanotecnologie i vari modelli e alcune best practice di trasferimento tecnologico. In questa prima giornata il dott. Heber Verri e la dott.ssa Paola Urbani hanno presentato il nuovo modello di trasferimento tecnologico PhD TTãIndex Model.

PhD TT è una realtà italiana completamente indipendente specializzata in trasferimento tecnologico, è un acceleratore organizzato per il Go to Venture Practice, orientata al mondo delle Lifes Sciences.

PhD TT ha sviluppato un nuovo modello di trasferimento tecnologico: il PhD TT©INDEX MODEL dedicato alla generazione di valore dell'innovazione, focalizzato alla riduzione dei rischi delle opportunità di investimento a sostegno della ricerca.

I ricercatori intervengono attivamente nell'analisi iniziale di fattibilità e nella costituzione della futura società (start-up), con l'obiettivo di attrarre capitale di rischio utile a sostenere la fase del trasferimento tecnologico nella visione della "Research for go-to-market".

Il modello PhD TT nasce da un bisogno del mercato, quello di far dialogare due mondi estremamente diversi tra loro: il mondo della ricerca e il mondo degli investimenti.

PhD TT supporta tutte le attività in collaborazione con il TTO - CNR Nanotec con un team di lavoro esperto e grazie a un comitato scientifico-economico qualificato.

In occasione dell'evento del 19/7 u.s. al CNR Nanotec di Lecce, PHD TT ha presentato il proprio track record, dove si sono potuti valutare in dettaglio i casi di successo di intervento del PhD TT©INDEX MODEL.

Disordered serendipity: a glassy path to discovery

A workshop in honour of Giorgio Parisi’s 70th birthday

September 19-21, 2018 - Roma

Sapienza University

With the occasion of celebrating Giorgio Parisi 70th birthday, the conference "Disordered serendipity: a glassy path to discovery" brings to Rome many among the world-leading experts in the field of complex systems. In order to properly represent the many fields of research where Giorgio Parisi gave a relevant contribution in his studies of disordered systems, the conference covers a broad spectrum of topics: from  fundamental and rigorous analysis of the statistical mechanics of disorder systems to applications in biology and computer science. These subjects are deeply interconnected since they are characterized by the presence of glassy behavior.
