The project is based on the fusion of the scientific skills of both the research laboratory and the two researchers who will be hired with the technical skills of the two companies in the construction field.
The preparation work for the manufacturing process of the photovoltaic devices will be done in the university laboratory, however a good part of the work will take place in the companies to optimize the process in order to be perfectly integrated into the high technological innovation products of Manni Green Tech and ISOPAN.
The manufacturing process must be designed and refined according to the technologies used in the prefabricated buildings and building systems of the two companies: deposition temperatures, material sprays, treatments, etc.
It is therefore expected that: 1-ISOPAN can provide the substrates that can act as a basis for the photovoltaic modules; 2-Manni Green Tech can devise solutions for a complete integration of Isopan photovoltaic panels.
The research fellow who will deal with the materials and the preparation of the nanoparticles will interface with the ISOPAN technicians, choosing and also designing isopan panels that are suitable for this type of application.
The research fellow who will be responsible for preparing the layers and completing the photovoltaic devices will interface with Manni Green Tech technicians for the design of the modules and integration solutions.

The materials produced will be analyzed through advanced microscopy techniques such as atomic force microscopy and electron microscopy. It will then be possible to evaluate the size and shape of the nanoparticles. The chemical characterization will instead be entrusted to X-ray, Raman and “energy dispersive x-ray (EDX)” analyzes present in the laboratories.
Films made with nanoparticles will be studied with similar methods, it will be necessary to produce films with thicknesses no greater than 6 microns (absorber material), conductivity will be measured through the electrical measurement system (current-voltage) present in the laboratory.
The finished photovoltaic cells will be measured with a solar simulation system, the conversion efficiency, the electrical capacity, the number of carriers, etc. will be analyzed.

Beyond the physical and electrical qualities widely analyzed with the methods mentioned above, the true meter of the quality of the work carried out will give you the measure of the conversion efficiency that we want to exceed 10% efficiency in the laboratory and 5% on a large scale ( on isopan modules). Although we can think that 5% is a low value, in reality we want to make the ISOPAN insulating coating panel energetically active while keeping the cost as low as possible. Solar conversion into electricity will therefore be a plus at minimal cost, making even a low conversion efficiency attractive.

As part of the ESF Communication Plan, the project members will participate in the promotion of the project organized by the Veneto Region, both during and at the end of the research paths, dissemination and comparison events during which the proponents guarantee their contribution. participating in organized meetings and other qualitative monitoring activities.
