Investigation on Ternary Oxide BaSnO3 Based Photoanode for Dye Sensitized Solar Cell Applications

Abstract

The ongoing advancement of the Internet of Things (IoT) has accelerated the need for efficient, low-cost and scalable energy harvesting solutions to power the increasingly diverse range of IoT devices. As IoT devices demand continuous energy sources to operate in various environments, energy solutions need to be efficient, cost-effective and capable of functioning in low-light conditions. Dye sensitized solar cell (DSSC) have emerged as promising candidates for this purpose due to their power conversion efficiency (PCE) even under dim light conditions, flexibility and ease of fabrication. These characteristics make DSSC particularly attractive for powering portable and flexible electronic devices used in IoT applications. newlineA critical component influencing the performance of DSSC is the photoanode, where optimizing the materials and nanostructures can significantly improve charge transport, light absorption and overall cell efficiency. In this context, the present study explores the potential of BSO, a wide-bandgap perovskite oxide, as an alternative to the traditional TiO2-based photoanodes. BSO is known for its high electron mobility and thermal stability, making it an ideal candidate for improving DSSC performance. However, to fully harness its potential, the material must be engineered to address the inherent limitations of BSO, such as poor light absorption and charge recombination newline
