Resolving the Hydrophobicity of Me-4PACz Hole Transport Layer for High-Efficiency Inverted Perovskite Solar Cells
Kashimul Hossain, Ashish Kulkarni, Urvashi Bothra +4
[4-(3,6-dimethyl-9H-carbazole-9-yl)butyl]phosphonic acid (Me-4PACz) self-assembled monolayer (SAM) has been employed in perovskite single junction and tandem devices demonstrating…
Characterizing the Influence of Charge Extraction Layers on the Performance of Triple-Cation Perovskite Solar Cells
Johanna Siekmann, Ashish Kulkarni, Samah Akel +4
Selecting suitable charge transport layers and suppressing non-radiative recombination at interfaces to the absorber layer are vital to maximize the efficiency of halide perovskite…
A Universal Strategy of Perovskite Ink-Substrate Interaction to Overcome the Poor Wettability of a Self-Assembled Monolayer for Reproducible Perovskite Solar Cells
Ashish Kulkarni, Ranjini Sarkar, Samah Akel +6
Perovskite solar cells employing self assembled monolayers such as Me-4PACz as hole transport layer has been reported to demonstrate high device efficiency. However, the poor perov…
Negative Capacitance and Inverted Hysteresis: Matching Features in Perovskite Solar Cells
Agustin O. Alvarez, Ramon Arcas, Clara A. Aranda +4
Negative capacitance at the low-frequency domain and inverted hysteresis are familiar features in perovskite solar cells, where the origin is still under discussion. Here we use Im…
Crystal orientation and grain size: do they determine optoelectronic properties of MAPbI3 perovskite?
Loreta A. Muscarella, Eline M. Hutter, Sandy Sanchez +5
It is thought that growing large, oriented grains of perovskite can lead to more efficient devices. We study MAPbI3 films fabricated via Flash Infrared Annealing (FIRA) consisting…
The perovskite/transport layer interfaces dominate non-radiative recombination in efficient perovskite solar cells
Martin Stolterfoht, Pietro Caprioglio, Christian M. Wolff +12
Charge transport layers (CTLs) are key components of diffusion controlled perovskite solar cells, however, they can induce additional non-radiative recombination pathways which lim…
