ABSTRACT
Recent advances on the novel design to improve the electrochemical performance parameters of metal sulfides/conducting polymer composites are being researched as most metal sulfides have. Because of their low electrical conductivity, it can result in low efficiency. To increase the electronic conductivity of metal sulfides (MSx), researchers combined carbon materials such as graphene oxide (GO), reduced graphene oxide (rGO), and carbon nanotubes (CNTs), and further, the modification with carbon improved the electrical conductivity, thereby increasing overall performance. Organic–inorganic hybrid photovoltaic devices have the merit of both materials in a single energy harvesting device. In addition they have lightweight, low cost, and can be fabricated on flexible surfaces achieving scalable solar power conversion. Conductive polymer, an organic light-absorbing material, can optimize photocurrent and photovoltage, enhancing the capacity of organic photovoltaic cells (OPVs).
Hence the present chapter covers the current challenges of hybrid solar cells aimed at the improvement of efficiency, development of materials for light-harvesting and charge transport. Carbon materials (with or without metal sulfides) synthesized by modest methods and their composites with the polymers like polyethylenedioxythiophene (PEDOT), polystyrene sulfonate (PSS), and polyhexahydrotriazine (PHT) using easy solution methods followed in fabrication of organic solar cells (OSCs) with improved power conversion efficiency.
