Characterization, reliability and stability study of a-Si/c-Si HTJ solar cell

Among all semiconductor materials Silicon has been taking dominating place in photovoltaics market for decades. Silicon is the second abundant material on earth´s crust after oxygen, its non-toxic and stable. As well as its optoelectronic properties also make it great choice to be used as well as its price. Si-HJ performance improvements often involve innovations in materials, device architecture, and manufacturing processes. Researchers continue to explore ways to enhance the performance to make them more cost-effective and efficient. While performance enhancements through innovations in materials, device architecture, and manufacturing processes are crucial for improving efficiency and cost-effectiveness, ensuring the long-term stability and reliability of these advancements is equally essential. That is why it is important to study the stability and reliability of silicon heterojunction (Si-HJ) solar cells. A comprehensive understanding of the solar cell's durability and performance under various conditions is vital for its successful integration into practical applications and the broader renewable energy landscape. Si-HJ solar cells were characterized by analyzing capacitance, doping concentration at different frequencies and current–voltage characteristic at dark condition and various light intensities. Light soaking, thermal stress and damp heat stresses were performed to investigate the reliability and stability of that cells.
