Abstract Perovskite solar cells hold promise for cost-effective, high-efficiency renewable energy generation; yet their commercialization is hindered by progress towards scalable fabrication methods. Roll-to-roll processing a promising solution large-scale production, and the incorporation of coated carbon electrodes offers several additional advantages, including low-cost manufacturing high-stability. Introducing compatible hole transporting layer between perovskite significantly improves performance. Here we present study comparing four interlayers (Spiro-MeOTAD, PTAA, PEDOT, P3HT) in printed devices, assessing efficiency, stability, scalability. Our results reveal that spiro-MeOTAD PTAA was not with electrode however PEDOT P3HT showed results. Beyond photovoltaic performance, comparison terms toxicity, cost reveals can be superior choice scaling up manufacturing. These findings offer valuable insights optimizing performance production via roll-to-roll printing.

Abstract Thermally evaporated C 60 is a near-ubiquitous electron transport layer in state-of-the-art p–i–n perovskite-based solar cells. As perovskite photovoltaic technologies are moving toward industrialization, batch-to-batch reproducibility of device performances becomes crucial. Here, we show that commercial as-received (99.75% pure) source materials may coalesce during repeated thermal evaporation processes, jeopardizing such reproducibility. We find the coalescence due to oxygen present initial powder and leads formation deep states within bandgap, resulting systematic decrease cell performance. However, further purification (through sublimation) 99.95% before found hinder coalescence, with associated being fully reproducible after processing. verify universality this behavior on perovskite/silicon tandem cells by demonstrating their open-circuit voltages fill factors remain at 1950 mV 81% respectively, over eight processes using same sublimed material. Notably, one these achieved certified power conversion efficiency 30.9%. These findings provide insights crucial for advancement towards scaled production high process yield.
