Impressive Research enabled with our R&D tools
Boosting Perovskite Solar Cell Efficiency with Self-Assembled Monolayers
Self-assembled hole-selective contact for efficient Sn-Pb perovskite solar cells and all-perovskite tandems
Zhu, J., Huang, X., Luo, Y. et al. Nat .Comm., 240 (2025). https://doi.org/10.1038/s41467-024-55492-4
Researchers from Sichuan University, Fujian Normal University, and Xiamen University have developed new self-assembled monolayers (SAMs) for more efficient perovskite solar cells. These SAMs, based on a donor-acceptor molecule with oligoether side chains of different lengths, act as hole-selective contacts (HSCs), improving charge extraction and reducing defects in Sn-Pb perovskite films. The best proposed SAM led to a 23.54% efficiency in single-junction cells and 28.61% in all-perovskite tandem solar cells. The improved performance is attributed to the enhanced perovskite film quality, reduced non-radiative losses and superior hole extraction.
PAIOS was used to perform electrochemical impedance spectroscopy (EIS) measurements and Mott-Schottky analyses. These measurements are used to characterize the electrical properties of the solar cells.
• Mott-Schottky analyses are used to determine the built-in potential of the solar cell.
• EIS gives information about the device's charge transport and recombination processes. Here, the EIS results demonstrated the suppressed non-radiative recombination losses in the devices with a SAM compared to the control solar cell.

At Fluxim, our research drives innovation. When you use our software or instruments, you benefit from the expertise of researchers who truly understand your work.
Our latest study, led by Sandra Jenatsch with Edoardo Stanzani and Dr. Stefano Sem, investigates the degradation mechanisms in thermally activated delayed fluorescence (TADF) OLEDs. We identified hole traps at the HTL/EML interface as the key factor reducing efficiency, offering new insights to enhance the operational stability and lifespan of OLEDs for commercial displays.
How our R&D tools contributed:
Setfos was used to fit the device's electrical characteristics and simulated the impact of the trap states on the device's behaviour. With Paios, we performed intermittent electro-optical tests during the device degradation studies, such as steady-state JV characterization and C-f analyses. Litos stressed our OLEDs under constant current and allowed us to record their emission during the degradation analyses.
23.2% efficient low band gap perovskite solar cells with cyanogen management. Energy & Environmental Science
Perera, W. H. K., Webb, et al., Energy Environ. Sci., 18, 439, (2025)
https://doi.org/10.1039/d4ee03001j
This multi-institutional research team has made significant progress in improving the efficiency and stability of perovskite solar cells (PSCs). This study addresses key challenges in tin-based PSCs, particularly those utilizing PEDOT:PSS as a hole transport material (HTL). The team identified that amine-containing organic cations can de-dope PEDOT:PSS, leading to performance losses. While thiocyanate additives partially recover performance, they compromise stability due to cyanogen formation in the presence of moisture. To mitigate this issue, the researchers incorporated an iodine reductant (benzyl hydrazine chloride, BHC) in lead-tin PSCs. This approach resulted in a power conversion efficiency of 23.2%, one of the highest reported for lead-tin PSCs, along with a 66% enhancement in TS80 lifetime under maximum power point tracking and ambient conditions.
Use of Fluxim Tools:
PAIOS was used to performed transient photocurrent (TPC) and intensity-modulated photocurrent spectroscopy (IMPS) measurements. These techniques helped identify increased ion migration in perovskite devices prepared on PEDOT:PSS. The TPC measurements confirmed the reduction in trap density upon the addition of thiocyanate (SCN⁻).

New Research Blog
Perovskite-silicon tandem solar cells are revolutionizing photovoltaics. Optimizing current matching between layers is critical for achieving peak efficiency. A mismatch can lead to power losses, limiting overall performance. In this blog, we explore how optical and electrical simulations help fine-tune device design, ensuring that both sub-cells generate maximum power.
