UNVEILING THE CARBON CONTENT: A COMPREHENSIVE ANALYSIS OF SILICON-CARBON ALLOYS

Аннотация

This study explores the optimization of passivation techniques for monocrystalline solar cells through the assessment of carbon content in silicon-carbon alloys. Passivation layers play a critical role in enhancing the efficiency and performance of solar cells by reducing recombination losses at the semiconductor surface. Silicon-carbon alloys offer a promising avenue for passivation due to their tunable properties and compatibility with existing manufacturing processes. By systematically varying the carbon content in silicon-carbon alloys, this research investigates its impact on passivation quality, surface recombination velocity, and photovoltaic device performance. Characterization techniques such as spectroscopic ellipsometry, surface photovoltage measurements, and photoluminescence imaging are employed to assess passivation layer thickness, interface quality, and carrier lifetime. The findings provide valuable insights into the role of carbon content in optimizing passivation effectiveness and offer pathways for enhancing the efficiency and stability of monocrystalline solar cells.
