Advancing Dye-Sensitized Solar Cells: Synergistic Effects of Polyaniline, Graphene Oxide, and Carbon Nanotubes for Enhanced Efficiency and Sustainability Developments

This paper provides an in-depth look at the latest developments in dye-sensitized solar cell (DSSC) technology. It focuses on the use of special materials, like polyaniline (PANI), graphene oxide (GO), and carbon nanotubes (CNTs). These materials improve the efficiency and stability of solar cells, and this study offers significant insights into their characteristics and practical uses. This article examines major trends in material selection, structural optimization, and manufacturing procedures by juxtaposing results from scientific literature with advancements in the patent arena, addressing the issues of developing next-generation solar cell designs. We examine the synergistic effects of PANI's stability, GO's electrical conductivity, and CNTs' mechanical strength, highlighting their roles in enhancing light absorption, charge transfer efficiency, and overall device longevity. Bibliometric data from sites, like Scopus and Lens.org, indicate substantial advancements in energy conversion efficiency and decreases in charge transfer resistance. Patents, like WO 2020 and EP3824-B1, illustrate the increasing significance of flexibility, resilience, and scalability in solar cell designs. Biopolymer-based electrolytes made from chitosan, guar gum, and starch are examples of sustainable solutions that show better ionic conductivity and mechanical stability, making them eco-friendly choices. This paper highlights the significance of nano and microfillers in enhancing electron mobility and minimizing resistive losses. Practical implementations, including photovoltaic chargers and flexible solar panels, illustrate the conversion of theoretical advancements into functional technologies. The study delineates future research avenues, promoting the utilization of nanocomposites and catalytic materials to enhance solar cell performance and thus facilitate sustainable and scalable energy solutions to address escalating global energy demands.
