Morphology stabilization strategies for small-molecule bulk heterojunction photovoltaics

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

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 ...

Hybrid Heterojunctions of Solution-Processed Semiconducting 2D Transition Metal Dichalcogenides

Kevin Sivula, Nestor Guijarro Carratala, Xavier Adrian Jeanbourquin, Natalie Renuka Banerji, Xiaoyun Yu, Muhammad Aiman Bin Rahmanudin Hamdan

Exfoliated transition metal dichalcogenides (2D-TMDs) are attractive light-harvesting materials for large-area and inexpensive solar energy conversion given their ability to form highly tolerant heterojunctions. However, the preparation of large-area heter ...

Semiconducting alternating multi-block copolymers via a di-functionalized macromonomer approach

Kevin Sivula, Liang Yao, Nestor Guijarro Carratala, Xavier Adrian Jeanbourquin, Andrea Gasperini, Muhammad Aiman Bin Rahmanudin Hamdan

The development of fully-conjugated semiconducting block-copolymers is an important goal for organic electronics, but to date has been almost exclusively limited to materials containing poly(3-alkylthiophenes). Here we present the prototype of a class of f ...

CuInGaS2 photocathodes treated with SbX3 (X = Cl, I): the effect of the halide on solar water splitting performance

Kevin Sivula, Nestor Guijarro Carratala, Florian Le Formal, Xavier Adrian Jeanbourquin, Xiaoyun Yu, Mathieu Steven Prévot, Pauline Bornoz, Wiktor Stefan Bourée

The realization of photoelectrochemical tandem cells for efficient solar-to-hydrogen energy conversion is currently impeded by the lack of inexpensive, stable, and efficient photocathodes. The family of sulfide chalcopyrites (CuInxGa1-xS2) has recently dem ...
