Morphology stabilization strategies for small-molecule bulk heterojunction photovoltaics

Kevin Sivula, Xavier Adrian Jeanbourquin, Simon Hänni, Muhammad Aiman Bin Rahmanudin Hamdan, Emilie Aude Marie Ripaud, Arvindh Sekar, Liang Yao

The greater crystallinity of solution-processed small-molecule organic semiconductors, compared to their polymer counterparts, renders the bulk heterojunction (BHJ) more susceptible to phase separation under thermal stress, decreasing device performance. H ...

Strategies for Doped Nanocrystalline Silicon Integration in Silicon Heterojunction Solar Cells

Christophe Ballif, Aïcha Hessler-Wyser, Antoine Descoeudres, Niels Holm, Martial Duchamp, Stefaan De Wolf, Jonas Geissbühler, Johannes Peter Seif, Simon Hänni, Gizem Nogay, Martin Ledinsky

Carrier collection in silicon heterojunction (SHJ) solar cells is usually achieved by doped amorphous silicon layers of a few nanometers, deposited at opposite sides of the crystalline silicon wafer. These layers are often defect-rich, resulting in modest ...

Quantification of Valleys of Randomly Textured Substrates as a Function of Opening Angle: Correlation to the Defect Density in Intrinsic nc-Si:H

Simon Hänni, Jan-Willem Alexander Schüttauf

Optical and electrical properties of hydrogenated nanocrystalline silicon (nc-Si:H) solar cells are strongly influenced by the morphology of underlying substrates. By texturing the substrates, the photogenerated current of nc-Si:H solar cells can increase ...
