Photovoltaic or solar cells (SC) devices –that transform light into electricity- have been extensively studied in the last decades since they represent a promising way to exploit the sun energy. Currently, perovskite-based solar cells(SC) are receiving increasing attention due to their low cost and high efficiency. They are very promising as an alternative for the existing ones, but still need to advance to reach higher efficiency and durability and require synthesis methods compatible with the industrial production of CMOS devices at wafer scale. These recent SC are mostly fabricated via wet methods in planar architecture. Inherent to the nature of the wet approaches, usually appear several drawbacks as contaminations and chemical reactions on the interfaces that might result deterioration of the SC performance.
PlasmaPerovSol main objective is the fabrication of a complete perovskite solar cell device by a full plasma and vacuum integrated process carried out under the premises of the “one reactor concept”. Thus, the different components of the solar cell will be deposited sequentially within a vacuum reactor avoiding exposition of the materials and interfaces to air or solvents. The technology developed by the hosting group combine vacuum deposition assisted by plasma that permits the fabrication of conformal layers over a large variety of templates. This approach is also proposed here to fabricate conformal multilayers over 1D scaffold that will push the advantages of one-dimensional SC. Plasma and vacuum processes present as advantage the high purity and stoichiometric control on the deposition within an ample range of materials compositions. The synthesis approach is compatible with large scale industrial production and allows the fabrication of SC on processable and flexible substrates. At the same time, the low temperatures used make the approach compatible with current CMOS technology and by using masks permits their integration on preformed devices.

The development of Solid Oxide Fuel Cells (SOFCs) operating on hydrocarbon fuels (natural gas, biofuel,LPG) is the key to their short to medium term broad commercialization. The development of direct HC SOFCs still meets lot of challenges and problems arising from the fact that the anode materials operate under severe conditions leading to low activity towards reforming and oxidation reactions, fast deactivation due to carbon formation and instability due to the presence of sulphur compounds. Although research on these issues is intensive, no major technological breakthroughs have been so far with respect to robust operation, sufficient lifetime and competitive cost. T-CELL proposes a novel electrochemical approach aiming at tackling these problems by a comprehensive effort to define, explore, characterize, develop and realize a radically new triode approach to SOFC technology means of an integrated approach based both on materials development and on the deployment of an innovative cell design that permits the effective control of electrocatalytic activity under steam or dry reforming conditions. The novelty of the proposed work lies in the pioneering effort to apply Ni-modified materials electrodes of proven advanced tolerance, as anodic electrodes in SOFCs and in the exploitation of our novel triode SOFC concept which introduces a new controllable variable into fuel cell operation. In order to provide a proof of concept of the stackability of triode cells, a triode SOFC stack consisting of at least 4 repeating units will be developed and its performance will be evaluated under methane and steam co-feed, in presence of a small concentration of sulphur compound.

The general objective of the ‘CERAMGLASS’ project is to reduce the environment impact of thermal treatment of ceramics by the successful application of an innovative laser-furnace technology on planar ceramics and glass. The project plans to construct a pilot plant based on the innovative combination of a continuous furnace and a scanning laser. It aims at demonstrating a considerable reduction in energy consumption and the industrial scalability of the process. The project primarily aims at showing that it is feasible to produce robust ceramic tile of only 4 mm thick. This would represent a 50% reduction in tile thickness, with consequent reduction in consumption of raw source materials. The project will adapt decoration compositions with more environmentally friendly materials by using the laser processing. Specifically it will adapt screen printing decorations to third-fire products with lustre and metallic effects and decoration inks for planar glass. The replacement of toxic starting materials will allow a minimisation of CO2 and other gas emissions, toxic residues and a reduction of the energy consumption of the process.
