Perovskite-Silicon Tandem Solar Cells: Basics to Latest Updates with Challenges
摘要
The perovskite-silicon tandem solar cells (PSTSCs) have gained a lot of attention since they have the potential to revolutionize entire photovoltaic industry. They utilize the proven performance and stability of silicon solar cell along with high efficiency of the perovskite materials. It is anticipated that this combination will outperform single-junction silicon solar cells in terms of efficiency and increase the accessibility and competitiveness of solar energy. Single-junction perovskite solar cells have achieved the power conversion efficiency (PCE) above 26% while silicon solar cells have over 25% but it is only in the tandem arrangement that the Shockley–Queisser efficiency limit was surpassed recording PCEs of 33%. Yet, concerns toward stability of perovskite materials are still hindering the possibilities of high efficiency and durable PSTSCs. This chapter aims to analyze the trends and developments in field of PSTSC, covering last ten years and presenting in detail the state of the art, persisting issues, and manufacturing processes of tandem solar cells. Moreover, in this context, the chapter presents existing and new strategies to tackle these issues, with particular regard to material stability, scalability, and market penetration. Finally, this chapter sets forth a vision for the future of efficient, scalable, and profitable PSTSCs.
