Abstract:

For the first time worldwide, AIDSSC project proposes to develop and validate an optoelectronic neural network prototype based on dye-sensitized solar cells for zero electric power consumption in the outdoor and indoor lighting conditions. The European Green Deal 2021 proposes ambitious environmental goals which require a green transformation of many sectors of society, in especially a sustainable development of urban areas, “smart city”, being a challenge of key importance. The transformative potential of artificial intelligence (AI) to contribute to the achievement of the goals of a green transition have been increasingly and prominently highlighted. At the same time, digital technologies such as AI considerably increase energy and resource consumption and create risks of adverse environmental effects. In this context, the solar cells open a new perspective as the most suitable candidate for zero electric power consumption. The dye-sensitized solar cell (DSSC) has the essential characteristics that could make these cells the ideal candidate for artificial intelligence system with zero electric power consumption. A singular preliminary proof of the DSSCs’ learning capabilities was highlighted by Gratzel, the inventor of DSSC, using the exposure time as a cue for learning under 1 sun-simulated conditions. This new perspective for AI devices which are the optically learning solar cells, have the potential to serve as building blocks for intelligent optoelectronics enabling visually interacting machines that operate at minimal power and zero electric power consumption, in both outdoor and indoor lighting conditions.

In this context, AIDSSC project aims to demonstrate that the optoelectronic neural network working prototype based on dye-sensitized solar cells is a technically and economically credible concept for the artificial intelligence devices.

Abstract:

For the first time, GETICA project proposes to develop and validate an energy independent and combined fully automated greenhouse standalone prototype based on dye sensitized solar cells (DSSCs), as an ongoing and complementary research of the project team. As an important part of Agriculture 4.0 strategy, agrivoltaics can achieve synergistic benefits by growing agricultural plants under raised solar panels. The main limitations of the integration in greenhouse concern the fact that classical PV cells do not transmit sunlight and form a permanent shadow region which has negative effects on production, reducing the crop growth or the amount of biomass. Simple manufacturing process, the low fabrication cost, flexibility in scaling, low material usage and low light level sensitivity, but mainly the variation in color and transparency of the dye sensitized solar cell (DSSC), one of the third generation of PV cells, are essential characteristics that could make these cells the ideal candidate for greenhouse application. To our knowledge (as far as we are aware), no DSSC has been applied in greenhouse for plant growth and energy saving worldwide. We propose the solar radiation manipulation using DSSCs based on UV dye for the protection cells and DNA from damaging UV radiation as well as scavenge free radicals, preventing further cellular damage or IR dye for reducing the temperature of the greenhouse air which leads to an increase in crop production. Moreover, it will be sought reducing production cost of the greenhouse using 3D printing of the modular roofs and DSSCs based on the natural dyes and a low-cost maintenance given by near zero energy input from conventional sources and decreasing the water consumption in irrigation. In this context, GETICA project aims to demonstrate the economic sustainability of this smart greenhouse based on DSSC in the real agriculture.

Abstract:

The project is aimed at using the expertise that involved in consortium entities acquired in materials science. The consortium consists of three representative national institutes: INCD for Chemistry and Petrochemistry – ICECHIM Bucharest, INCD for Electrochemistry and Condensed Matter - INCEMC Timisoara and INCD of Chemical Pharmaceutical - ICCF Bucharest, and of two prestigious universities: University POLITEHNICA of Bucharest and the University of Bucharest and a remarkable institute of Romanian Academy: Institute of Macromolecular Chemistry – Petru Poni Iasi. Although having great tradition and noteworthy results, the first five institutions face a series of problems, from the lack of financial funds, equipment and the aging employees for ICCF and partly for INCEMC and ICECHIM, to the lack of highly qualified staff required for recent investments in equipment for all 5 institutions. In this respect, the project attempts relaunching the activity in the first 5 institutions of the consortium, by putting together the existing competencies, so as to develop new technologies in order to obtain new materials with high performance properties. Given that, 3 of the research teams are specialized in polymers (ICECHIM, Petru Poni and UPB) the developed technologies will use the polymers as intermediates or as a component in the finished product. To this end it is envisaged getting the titanium nitride for prosthetic coatings via inorganic-organic polymer nanocomposites, obtaining photocatalytic materials and antibacterial coatings by sol- gel reactions, obtaining of short-life or one-time use biomaterials from aliphatic polyesters and micro or nanocellulose and the development of new polyphase materials with medium or long life, based on biopolymers, through 3D printing. The project intends the full use of A1, A2, B and C checks in order to increase the institutional performance of partners.

Abstract:

The alternatives to conventional silicon-based solar cells, dye-sensitized solar cells (DSSCs) attract great research interests because of low manufacturing cost and environmentally friendly character. Recently, Grätzel and coworkers have achieved a world record efficiency of 12.3% based on porphyrin dye sensitized TiO2 n-type DSSC.

However, the commercialization of DSSCs is still being postponed by their relatively lower efficiency. To further improve the energy conversion efficiency of DSSC up to 15% is of critical importance for the scale-up industrial application of this cheap and environmental friendly photovoltaic technology. Recently, the idea of tandem-DSSCs, with a theoretical photon to energy conversion efficiency (PCE) over 40%, has been raised.

TANDEL CELL project is aimed to obtain highly efficient photocathodes for dye-sensitized tandem solar cells based on nanocrystalline delafossite materials and the establishment of young independent research team in highly efficient dye-sensitized solar cells domain.
