Description of the Experience
The renewable energy sources that are regenerating at least at the same rate with which they are consumed or are not exhaustible in human time scale whose use does not affect the natural resources of future generations. These include solar energy offers the best prospects for use.
Solar radiation despite its poor and discontinuous intensity remains the most abundant and clean energy source on the earth's surface.
The energy sent by the Sun on the Earth is equal to that consumed by all humanity in one year at a time.
The devices can collect and transform directly the 'sun's energy into usable energy are solar thermal, solar concentrator and solar panels.
This work is the third generation of solar cells made from semiconductor materials comprising two devices:
- Organic solar cells - OPV - based on purely organic semiconductors
- hybrid solar cells - DSSC - based on interaction of an organic or organometallic molecule (dye or sensitizer) and an inorganic semiconductor (titania, TiO2).
- Grätzel cells (from the name of its inventor), are particular photoelectrochemical cells, consist of two slides conductors which act as electrodes.
- They are separated by a layer of titanium dioxide TiO2, also known as titania), from the active material (the natural dye) and the electrolytic solution.

Dissemination Seminar in Florence

31 October 2015 The seminar has been held in ITIS “A. Meucci” one of the schools involved within Goerudio project activities. Its main aim was to promote the results of the project toward a broad sample of stakeholders even overcrossing the number of people directly involved in the production of project outcomes. This purpose has been totally achieved especially thanks to the participation of students and teachers coming from different schools or from other classes instead of those ones directly involved within the project activities.
