Sustainability of Organic Dye-Sensitized Solar Cells: The Role of Chemical Synthesis
The
synthesis of a novel and efficient π-extended D-A-π-A
organic sensitizer (<b>G3</b>, η = 8.64%) for dye-sensitized
solar cells has been accomplished by applying the green chemistry
pillars, aiming at overriding traditional routes involving organometallic
intermediates with innovative synthetic strategies for reducing the
waste burden and dye production costs. It has been demonstrated that
the obtainment of a complex target sensitizer can be exclusively pursued
via direct arylation reactions. Green metrics comparison with those
of a traditional synthetic pathway clearly indicates that the new
approach has a lower environmental impact in terms of chemical procedures
and generated wastes, stressing the importance of the synergy between
the molecular design and the synthetic plan in the framework of environmentally
friendly routes to back up sustainable development of third-generation
photovoltaics. Additionally, the stability of the <b>G3</b>-based
photovoltaic devices was also investigated in aging tests on large
area devices, evidencing the excellent potentialities of the proposed
structure for all practical applications involving inorganic semiconductor/organic
dye interfaces
