Abstract <p>Many chemists are keen to advocate improved materials and fragments for the fabrication of solar devices with enhanced photochemical conversion efficiency. Here, we focused on the fabrication of polyaniline-based nanocomposite designs that were transformed to expand them technologically through allied hybrid materials. These nanocomposite materials are very operative in present-day energy storage devices because of their amplified dynamic catalytic surface area and boosted charge transfer from the counter electrode to the electrolyte, which demonstrates potential candidate to be employed as the counter electrode in dye-sensitized solar cells. Consequently, an inclusive investigation of polyaniline-based counter electrode as an intrinsic conducting polymer has been accelerated in photovoltaic solar cells, which exploits the skills of electrochemical tools to transform solar radiation effectively into electrical power, which will signifyan eco-friendly and high-demand energy source towards low carbon emissions. This could be an imminent revolution that benefits administrators to preserve control, and a balanced tactic to further gain practical requirements.</p>
