Crack-Free Monolayer Graphene Interlayer for Improving Perovskite Crystallinity and Energy Level Alignment in Efficient Inverted Perovskite Solar Cells

Mohammad Khaja Nazeeruddin, Kumar Varoon Agrawal, Yen-Cheng Liu, Hiroyuki Kanda, Shiqi Huang

Inverted planar perovskite solar cells (PSCs) have intrigued great promise in negative hysteresis, simple fabrication process, and flexible substrate implementation, in which the shared hole transport materiel is NiOx. However, the low-temperature solution ...

Tumor-specific cytolytic CD4 T cells mediate immunity against human cancer

Hatice Altug, Alexander Mathis, George Coukos, Xiaokang Li, Yen-Cheng Liu, David Gfeller, Pedro Romero, Alexandre Harari, Amélie Cachot, Margaux Saillard

CD4 T cells have been implicated in cancer immunity for their helper functions. Moreover, their direct cytotoxic potential has been shown in some patients with cancer. Here, by mining single-cell RNA-seq datasets, we identified CD4 T cell clusters displayi ...

Expanded Phase Distribution in Low Average Layer-Number 2D Perovskite Films: Toward Efficient Semitransparent Solar Cells

Mohammad Khaja Nazeeruddin, Paul Joseph Dyson, Bin Ding, Yong Ding, Yen-Cheng Liu, Hiroyuki Kanda, Xuehui Liu, Cheng Liu, Hao Huang

The application of low average layer-number (< n & rang;

Tuning structural isomers of phenylenediammonium to afford efficient and stable perovskite solar cells and modules

Mohammad Khaja Nazeeruddin, Paul Joseph Dyson, Bin Ding, Yen-Cheng Liu, Hiroyuki Kanda, Keith Gregory Brooks

Salt passivation of perovskite often results in formation of 2D perovskite layers, which impaired charge transport behaviour. Here, the authors study the energy barrier of 2D perovskite formation upon passivation by different iodide salt, and provide insig ...

Crystallographically Oriented Hybrid Perovskites via Thermal Vacuum Codeposition

Mohammad Khaja Nazeeruddin, Mounir Driss Mensi, Yen-Cheng Liu, Cristina Roldán Carmona, Hiroyuki Kanda, Nadja Isabelle Desiree Klipfel, Cheng Liu, Maria Cristina Momblona Rincón

Hybrid lead halide perovskites typically form polycrystalline films that have multiple grain sizes and surface defects. A key engineering challenge toward commercialization is therefore the production of homogeneous, defect-free largearea devices achieving ...
