Cost Analysis of Perovskite‐Organic Tandem Solar Cell

The photovoltaic technology is witnessing rapid advancements, with perovskite‐organic tandem solar cells (PO‐TSCs) emerging as a highly promising option among perovskite‐based solar cells. However, its cost analysis is still very much lacking. This study undertakes a comprehensive cost and economic analysis of PO‐TSCs, aiming to identify the gap with different device configurations and evaluate their commercialization potential. By employing a bottom‐up cost analysis model, various cost components such as materials, equipment, and maintenance are evaluated. The analysis reveals a manufacturing cost of 97.91 USD/m², with the PBDTT − 2F material in the organic solar cell being the dominant cost factor, accounting for 79.20%. Under the simulated assumptions, the module cost is 0.49 USD/W and the levelized cost of electricity is 4.8 cents/kW h. To assess the economic impact of different solar cell parameters on their performance, a sensitivity analysis is conducted, with particular emphasis on the rate of efficiency loss over time. The findings indicate that achieving a module efficiency of 25% and an operating time of 25 years, along with minimal loss rates, are crucial for economic viability. Although PO‐TSCs have higher initial material and module costs compared to planar single‐ junction perovskite cells, their superior photoelectric conversion efficiency and potential for cost reduction endow them with a competitive edge in the market. This study not only highlights the technical and economic feasibility of PO‐TSCs but also provides valuable insights for future technological progress and market strategies for PO‐TSCs.
