Enhancing Solar Photovoltaic Cell Efficiency: A Comparative Analysis of Advanced Materials and Manufacturing Techniques

This research paper investigates the enhancement of solar photovoltaic (PV) cell efficiency through a comparative analysis of advanced materials and manufacturing techniques. With the escalating demand for renewable energy solutions, improving the efficiency of solar cells is paramount. This study focuses on several promising materials including silicon, perovskite, CIGS, organic, and dye-sensitized options, alongside innovative manufacturing techniques such as roll-to-roll printing, ultrasonic spraying, and laser scribing. The methodology employed an experimental approach, where various prototypes were fabricated and tested under controlled laboratory conditions. Regression analysis was utilized to examine the impact of different materials and manufacturing techniques on solar cell performance. Key findings revealed that specific manufacturing techniques, particularly laser scribing, significantly enhance the efficiency of silicon-based cells. Moreover, perovskite cells displayed robust performance under varied environmental conditions, suggesting their broader application potential. Material enhancements such as sodium doping in CIGS cells were also shown to substantially increase efficiency. The implications of these findings are significant, offering insights into the effective integration of materials and techniques that could lead to more cost-effective and efficient solar energy systems. This study not only advances the academic understanding of photovoltaic technologies but also guides practical implementations in the solar industry.
