Inkjet printed mesoscopic perovskite solar cells with custom design capability

Frank Nüesch, Jakob Heier, Sina Abdolhosseinzadeh

Customizable solar cells are required for aesthetic indoor and outdoor photovoltaic deployment as well as for the freedom of design of small and portable power supplies. We demonstrate that drop on demand inkjet printing can be used for the fabrication of ...

Diyne-Functionalized Fullerene Self-Assembly for Thin Film Solid-State Polymerization

Jakob Heier, Gaëtan Wicht, Raffaele Mezzenga

C-60 fullerene derivatives bearing aliphatic chains can self-assemble into versatile supramolecular structures. Cross-linking of such self-assembled morphologies is an attractive approach to enhance the structural stability of these self-organized structur ...

Functional Ink Formulation for Printing and Coating of Graphene and Other 2D Materials: Challenges and Solutions

Frank Nüesch, Jakob Heier, Sina Abdolhosseinzadeh, Mohammad Jafarpour

The properties of 2D materials are unparalleled when compared to their 3D counterparts; many of these properties are a consequence of their size reduction to only a couple of atomic layers. Metallic, semiconducting, and insulating types can be found and fo ...

Nanocellulose-MXene Biomimetic Aerogels with Orientation-Tunable Electromagnetic Interference Shielding Performance

Frank Nüesch, Jakob Heier, Sina Abdolhosseinzadeh

Designing lightweight nanostructured aerogels for high-performance electromagnetic interference (EMI) shielding is crucial yet challenging. Ultrathin cellulose nanofibrils (CNFs) are employed for assisting in building ultralow-density, robust, and highly f ...

Dewetting-driven hierarchical self-assembly of small semiconducting molecules

Jakob Heier, Raffaele Mezzenga, Gian-Luca Bona

We describe the self-organization of PCBM and a cyanine dye on chemically patterned surfaces during spin coating from solution. On homogeneous surfaces, a transient bilayer forms, which in a later stage decomposes into PCBM droplets in a matrix of the cyan ...

Ultrafast charge transfer in solid-state films of pristine cyanine borate and blends with fullerene

Jacques-Edouard Moser, Frank Nüesch, Jakob Heier, Jelissa Risse

Photoinduced electron transfer in light-absorbing materials is the first step towards charge separation and extraction in small molecule-based organic solar cells. The excited state dynamics of the cyanine dye cation Cy3 paired with a tetraphenylborate cou ...
