  In recent years, many new materials have been developed and prepared to
improve the performance of light-harvesting technologies and to develop new and
attractive applications. The problem of stability of long-term operation of
various optoelectronic devices based on organic materials, both conjugated
polymers and small molecules of organic semiconductors (SMOSs), is becoming
relevant now. One way to solve this problem is to use carbon nanostructures,
such as carbon nanotubes and a large family of graphene-based materials, which
have enhanced stability, in carefully designed nanohybrid or nanocomposite
architectures that can be integrated into photosensitive layers and where their
potential is not yet know fully disclosed. Recently, a new trend has been seen
in this direction - the use of nanoscale materials for, first of all, the
conversion of light into electricity. The main goal of this approach is to
rationally design stable and highly efficient carbon-based hybrid nanomaterials
for optoelectrical applications, namely light harvesting/electricity
conversion, which can be implemented in real optoelectrical devices. In this
review, we will discuss the theoretical and experimental foundations of the
hybridization of carbon nanostructures (CNSs) with other materials to reveal
new optoelectronic properties and provide an overview of existing examples in
the literature that will predict interesting future perspectives for use in
future devices.
