In-depth Analyses of P-type Silicon Solar Cells by Laser-Induced Breakdown Spectroscopy (LIBS)

Following the rapid development in the field of renewable energy, the photovoltaic industry is rushing to meet the growing demand and is investing in processes, materials and research to achieve the necessary scale to reduce the cost of electricity produced by photovoltaic panels. Polycrystalline silicon photovoltaic cells are the most popular and economical cells in the market due to their cost-effective manufacturing methods and cheap substrates, with factories incorporating production quality control systems to continuously optimize the manufacturing process to maintain their efficiency and performance¹. In this context, we have analyzed polycrystalline silicon solar cells by LIBS laser induced breakdown spectroscopy to characterize the nature and determine the content of impurities present in these cells².
