Investigating the Influence of Temperature Variations on the Performance of Surface Plasmon-Enhanced Thin Film Solar Cells

Abstract

Advancements in the realm of solar energy conversion are pivotal as we seek to unlock the full potential of renewable energy sources. A fundamental challenge lies in enhancing the absorption of sunlight, spanning both the visible and infrared spectra, which holds the key to boosting overall efficiency. In this quest, surface plasmons (SPPs) have emerged as highly promising agents. A substantial body of literature has probed the myriad geometries of SPPs, meticulously investigating their influence on both optical and electrical characteristics, with a particular focus on their application in thin-film solar cells. Among these configurations, triangular SPPs have demonstrated exceptional promise, showing the potential to deliver optimal outcomes. The primary objective of this study is to delve into the intricate relationship between temperature variations and the performance of triangular SPPs, each measuring a diminutive 10×10 nm. We have undertaken a rigorous examination of key electrical parameters that include the short-circuit current, open-circuit voltage, series resistance, parallel resistance, and, crucially, overall efficiency. This investigation leverages the sophisticated capabilities of COMSOL Multiphysics, a state-of-the-art three-dimensional (3D) numerical simulation platform. By employing this cutting-edge tool, we can comprehensively explore the intricate interplay between semiconductor properties and electromagnetic phenomena. The findings that emerge from these simulations reveal an intriguing trend. As the temperature surpasses the critical threshold of 300 K, we observe a discernible decrease in the efficiency of the triangular SPPs. This observation underscores the vital role played by temperature in the performance of these plasmonic structures, shedding light on a previously understudied dimension in our ongoing pursuit of enhanced solar energy conversion efficiency. These insights represent a significant stride forward, paving the way for the development of nuanced strategies in the design and practical implementation of SPP-based solar energy conversion technologies. This progress brings us one step closer to realizing a sustainable energy future, where solar power stands as a robust and reliable source of clean energy.
