EFFECT OF TEMPERATURE AND DIELECTRIC CONSTANT ON THE PERFORMANCE OF SILICON SOLAR CELL
Abstract
This research investigates the combined effect of temperature and dielectric constant on the performance of silicon solar cells. The study focuses on understanding how variations in operating temperature and the dielectric properties of surface passivation layers influence key electrical parameters such as open-circuit voltage (VOC), short-circuit current (ISC), fill factor (FF), and overall conversion efficiency. Experimental and theoretical analyses were conducted to examine the behavior of silicon solar cells under different temperature conditions and dielectric environments. Results show that an increase in temperature leads to a reduction in VOC and efficiency due to enhanced carrier recombination and decreased bandgap energy, while ISC exhibits a slight increase. Furthermore, dielectric materials with higher permittivity significantly improve surface passivation by reducing surface recombination velocity, thereby enhancing VOC and overall cell efficiency. The findings demonstrate that optimizing temperature conditions and carefully selecting dielectric materials can substantially improve the performance and reliability of silicon solar cells. This study provides valuable insights for photovoltaic module design, material selection, and efficiency enhancement strategies in varying environmental conditions.
