All perovskite tandem solar cells (APTSC) are receiving significant attention from the solar cell community due to the rapid increase in power conversion efficiency (PCE), which has risen from less than 5% to over 28% since their initial demonstration [1,2]. All high-performing APTSCs currently use PEDOT: PSS as a hole transport layer. However, due to its acidic and hygroscopic nature, PEDOT: PSS is not an ideal candidate for solar cells [3]. Consequently, in this work, we explored various hole transport layers, including hole-selecting monolayers based on carbazole moieties, those without carbazole moieties, and inorganic hole transport layers such as NiOx. We will present a comparative analysis of the efficiency, light stability, and thermal stability of APTSCs utilizing these different layers at the interconnection. By investigating these alternative materials, we aim to enhance the overall performance and durability of perovskite tandem solar cells. Our findings indicate that some of these alternative hole transport layers show promise in improving the stability and efficiency of APTSCs. This research provides valuable insights into the development of more efficient and stable perovskite tandem solar cells, potentially leading to their broader adoption in the renewable energy sector.
