“…The nitrogen-doped Si wafers showed higher mechanical strength compared to the conventional wafers [54]. Increasing the flow rate of the inert gas during melting and solidification has a positive impact on reducing the melt contamination from the atmosphere [55] but it accelerates the coating degradation [56,57]. Also, less contamination and hence more homogenous ingots with no inclusions can be achieved by (i) rotating during the process [58,59] or stirring the melt with a magnetic field [60,61].…”

“…Also, to prevent the metallic impurities from diffusion into the melt, several researchers have attempted to coat the crucible interior with different types of ultra-purity layers [68][69][70][71]. Moreover, Hendawi et al [72,73] investigated key factors in silicon crystallization, including crucible types, coatings, and wetting principles, offering valuable insights for optimizing efficiency in the selection and use of crucibles and coatings.…”

Photovoltaic (PV) installations have experienced significant growth in the past 20 years. During this period, the solar industry has witnessed technological advances, cost reductions, and increased awareness of renewable energy’s benefits. As more than 90% of the commercial solar cells in the market are made from silicon, in this work we will focus on silicon-based solar cells. As PV research is a very dynamic field, we believe that there is a need to present an overview of the status of silicon solar cell manufacturing (from feedstock production to ingot processing to solar cell fabrication), including recycling and the use of artificial intelligence. Therefore, this work introduces the silicon solar cell value chain with cost and sustainability aspects. It provides an overview of the main manufacturing techniques for silicon ingots, specifically Czochralski and directional solidification, with a focus on highlighting their key characteristics. We discuss the major challenges in silicon ingot production for solar applications, particularly optimizing production yield, reducing costs, and improving efficiency to meet the continued high demand for solar cells. We review solar cell technology developments in recent years and the new trends. We briefly discuss the recycling aspects, and finally, we present how digitalization and artificial intelligence can aid in solving some of the current PV industry challenges.

Solar photovoltaic (SPV) systems installed on water bodies, i.e., floating solar PV (FSPV) and canal top solar PV (CTSPV), have gained significant propulsion in recent years, not only because of their enormous potential but also because of other additional co-benefits. This review article discusses the scope and potential of FSPV and CTSPV, an ambitious plan, and various upcoming FSPV projects in India. The review focuses on different degradation modes, failure mechanisms, characterization techniques and distinct factors influencing the degradation of SPVs operating in tropical climates. It was explored that potential induced degradation (PID) and materialistic degradation have a significant impact on the performance of SPV. The paper provides an overview of the test procedures outlined in IEC-61215 and IEC-62804 that pertain to SPV performance under hot and humid conditions. Additionally, it presents a comprehensive review of the various methodologies adopted for accelerated damp heat testing to predict the life of PV systems in such conditions, and their significant analytical and visual outcomes is elucidated. Also, till date, no simulation tool has been available to assess the long-term performance of SPV in a humid environment. As this energy generation technique is still in its infancy, this study will help many researchers and solar power developers recognize the impact of elevated and prolonged exposure to temperature and humidity on generation, degradation, and mode of failure for different SPV technologies.
