Organic-Inorganic Hybrid Nanomaterials for Photovoltaic Devices

Organic–inorganic hybrid photovoltaic devices belong to the fourth-generation photovoltaic technology. Almost in all fields, organic nanomaterials have great interest due to their characteristics features different from other nanomaterials. Thus, there are large number of literature reports available in the field of organic photovoltaic devices. When hybrid devices come with the combination of organic and inorganic nanostructures, then the power conversion efficiency will improve compared to the conventional devices. The mainly used organic nanostructures include carbon nanotubes (single, double and multi-walled), graphene, quantum dots and cadmium sulphide. Transition metal oxides, transition metal dichalcogenides, metal–organic frameworks and MXenes are the inorganic nanostructures used with hybrid devices. The characteristics features of all these two- and three-dimensional nanostructures are favourable for the efficiency improvement in photovoltaic devices. Their electrical, optical and morphological properties largely affect the hybrid system to boost the power conversion efficiency. This chapter discusses the features and applications of photovoltaic devices, the properties of organic–inorganic hybrid system and their applications with different organic–inorganic nanostructured systems.
