Abstract:
The large concern of global energy challenges has greatly increased the interest and investments in renewable and clean energy that can replace fossil fuel. Among all known systems to generate energy, solar power is the most promising one. Hence, no one doubts the important role that photovoltaics (PV) are going to play in the energy of the future. The main drawbacks of the current PV technologies are their high production cost and rigid structure in the case of traditional silicon and inorganic semiconductors, or their reduced efficiency and durability in the case of organic and DSSC photovoltaics. One of the bottlenecks of increasing the conversion efficiency in DSSC is the transport of photogenerated electrons. The general approach to surpass these limitations is employing one of the following strategies: doping, growing vertically oriented porous structures on top of the conducting substrate, interconnecting TiO2 nanoparticles with charge carriers to direct the photogenerated current or find alternative materials with higher electronic mobility. Due to the richness of its optical and electronic properties, 3D graphene is the material of choice for our proposed studies. The ability to develop free-standing 3D graphene structures with large specific surface area will enable the successful realization of fast transport channels of charge carriers, thus leading to high electrical conductivity. Moreover, by combining their good electrical conductivity with their porous structure, the 3D graphene structures will increase the photocurrent density of DSSC by enhancing light absorption (sensitizer loading), enabling efficient charge separation and light scattering. In this context, the general objective of the project is: to evaluate the functionality of the 3D graphene structures in optoelectronic devices, specifically in photovoltaic cells (DSSC).
