Deffects detection in Silicon Solar modules Using Electroluminescence method.
Abstract
ABSTRACT
Solar energy continues to emerge as a vital renewable energy source, making photovoltaic technology a critical area of research and development. The efficient functioning of solar cells is pivotal to harnessing solar energy effectively. However, defects in solar cells, arising during production or over time, can significantly reduce their performance and lifespan, posing challenges
to the solar industry. To address this issue, the Electroluminescence (EL) method has gained
prominence as a non-destructive and high-resolution technique for detecting defects in solar cells.
This report presents a comprehensive study on the implementation of the electroluminescence (EL) method as a powerful tool for detecting defects in solar cells.
It begins by giving a brief overview of how solar energy is generated and how it is tapped by the solar cells. it gives a detailed overview of solar cell defects, their types, and their impact on overall performance.
The principles and working mechanism of electroluminescence are elucidated, outlining the physics behind light emission in solar cells. The report describes the experimental setup required for EL imaging, including the specialized equipment and imaging systems utilized to capture and analyze electroluminescent images.
The report concludes by demonstrating that Electroluminescence method holds great promise as a powerful tool for detecting defects in solar cells. Its non-destructive nature, high-resolution imaging capabilities, and ability to identify various types of defects make it a valuable addition to the solar industry’s quality control and inspection practices.
