ABSTRACT
There is an urgent need to develop efficient solutions to convert
solar energy into a transportable and clean energy form, to limit
greenhouse gases emissions, and to contrast the fossil fuel depletion
[1, 2]. There are various possibilities to use solar energy, but the use
of semiconductor materials to convert solar light into either electri-
cal or chemical energy is one of the preferable solutions, because
they offer the possibility of low-cost applications distributed on
the territory, thus eliminating some of the drawbacks associated
with centralized energy production systems [3]. Delocalization of
energy production is an important target for sustainable chem-
istry and energy [4] for a better integration with territory and
reduction of eco-impact, reduction of fuel transport safety and cost
issues, etc.
