The widespread expansion in the use of inorganic solar cells remains limited
due to the high costs imposed by fabrication procedures involving elevated
temperature, high vacuum, and numerous lithographic steps. Organic solar
cells are considered a promising candidate to replace the expensive inorganic
solar cells based on silicon due to their potential for providing environmentally
safe, flexible, lightweight, inexpensive, and roll-to-roll feasible production
solar cells. However, the efficiency achieved in current organic solar
cells is quite low, yet quick and successive improvements render it as
a promising alternative. Polymer-inorganic nanoparticles offer an attract
strategy to combine the merits of organic and inorganic materials into
novel electronic and photonic systems, and can be used effectively to
improve the overall power conversion efficiency of organic photovoltaic
devices.
In this project, we will focus on the synthesis of inorganic nanoparticles
and tune their surface properties. Novel organic solar cells will be prepared
by using p-type polymer semiconductors (donor) and n-type fullerenes (acceptor)
units by clusterization with inorganic nanoparticles. Charge transport
in composites of inorganic nanoparticles and a conjugated polymer will
be investigated using a photovoltaic device structure. Our major aim is
to improve the overall efficiency by using the advantages of both polymers
and inorganic nanoparticles (tunable optical and electrical properties).
