Cost Analysis of Perovskite-Organic Tandem Solar Cell

Abstract

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.
