Computational Studies on the Stability of Organic-Inorganic Hybrid Halide Lead Perovskites
Perovskite-based solar cells are currently the most rapidly advancing photovoltaic technology but concerns about their long-term stability are still impeding full-scale commercialization. This thesis provides computational insights into some of the stabili ...
EPFL2024Axial-Equatorial Halide Ordering in Layered Hybrid Perovskites from Isotropic-Anisotropic 207Pb NMR
David Lyndon Emsley, Michael Allan Hope, Ümmügülsüm Günes, Manuel Cordova, Aditya Mishra
Bandgap-tuneable mixed-halide 3D perovskites are of interest for multi-junction solar cells, but suffer from photoinduced spatial halide segregation. Mixed-halide 2D perovskites are more resistant to halide segregation and are promising coatings for 3D per ...
Weinheim2024A thermotropic liquid crystal enables efficient and stable perovskite solar modules
Mohammad Khaja Nazeeruddin, Yong Ding, Bin Ding, Cheng Liu, Jian Xu
Perovskite solar cells have seen impressive progress in performance and stability, yet maintaining efficiency while scaling area remains a challenge. Here we find that additives commonly used to passivate large-area perovskite films often co-precipitate du ...

Mohammad Khaja Nazeeruddin, Bin Ding, Xianfu Zhang, Bo Chen, Chaohui Li, Yan Liu
Utilization of small molecules as passivation materials for perovskite solar cells (PSCs) has gained significant attention recently, with hundreds of small molecules demonstrating passivation effects. In this study, a high-accuracy machine learning model i ...
Weinheim2024Mixed ionic-electronic conduction in Ruddlesden-Popper and Dion-Jacobson layered hybrid perovskites with aromatic organic spacers
Michael Graetzel, Jovana Milic, Joachim Maier, Algirdas Ducinskas, Davide Moia, Mina Jung
The understanding of mixed ionic-electronic conductivity in hybrid perovskites has enabled major advances in the development of optoelectronic devices based on this class of materials. While recent investigations revealed the potential of using dimensional ...
Royal Soc Chemistry2024Data-Intensive Exploration of the Photoelectrochemical Responses of Main-Group Metal Sulfides
Materials that efficiently promote the thermodynamically uphill water-splitting reaction under solar illumination are essential for generating carbon-free ("green") hydrogen. Mapping out the combinatorial space of potential photocatalysts for this reaction ...
Amer Chemical Soc2024Synthesis and Characterization of Functionalized Spacer Cations for the Incorporation in Layered Perovskites
Layered hybrid organic-inorganic perovskite (LHOIP) materials are an emerging class of semiconductors endorsed as a more stable alternative compared to the more widely investigated 3D hybrid organic-inorganic halide perovskites (HOIP). Consisting of altern ...
EPFL2023Vapor Deposition of Perovskite Solar Cells
Quentin Jean-Marie Armand Guesnay
Thanks to the continuous improvement of crystalline silicon (c-Si) solar cells, largely dominating the market, photovoltaic electricity is nowadays the cheapest source of energy on the market. Yet, solar energy is far from being completely harvested, as t ...
EPFL2023Interface connection of functionalized carbon nanotubes for efficient and stable perovskite solar cells
Mohammad Khaja Nazeeruddin, Jianxing Xia, Ruiyuan Hu
The ionic defects of hetero-junction interfaces always attract and trap carriers via surface electrostatic forces, which are crucial for the efficiency and intrinsic stability of perovskite solar cells (PSCs). Herein, functionalized carbon nanotubes (CNTs) ...
ROYAL SOC CHEMISTRY2023Isomeric imidazole functionalized bithiophene-based hole transporting materials for stable perovskite solar cells
Mohammad Khaja Nazeeruddin, Jianxing Xia, Albertus Adrian Sutanto, Min Chen
2,2,7,7-tetrakis(N,N-dip-methoxyphenylamine)-9,9-spirobifluorene (spiro-OMeTAD) is a popular hole-transporting material (HTM) in perovskite solar cells (PSCs), However, it suffers from high-cost and stability issues, which need to be overcome for PSC comme ...
