Plasma-enhanced low temperature growth of silicon nanowires and hierarchical structures by using tin and indium catalysts.
Linwei Yu,Benedict O’Donnell,Pierre-Jean Alet,Pierre-Jean Alet,Sonia Conesa-Boj,Francesca Peiró,Jordi Arbiol,Pere Roca i Cabarrocas +7 more
TL;DR: Plasma-enhanced low temperature growth of silicon nanowires (SiNWs) and hierarchical structures via a vapor-liquid-solid (VLS) mechanism are investigated and tin is found to be more ideal than indium in achieving a better size and density control of the SiNWs.

Bismuth-catalyzed and doped silicon nanowires for one-pump-down fabrication of radial junction solar cells.
Linwei Yu,Franck Fortuna,Benedict O’Donnell,Benedict O’Donnell,Taewoo Jeon,Martin Foldyna,Gennaro Picardi,Pere Roca i Cabarrocas +7 more
TL;DR: This work provides the first evidence that catalyst doping in the SiNW cores, caused by incorporating Bi catalyst atoms as n-type dopant, can be utilized to fabricate radial junction solar cells, with a record open circuit voltage of V(oc) = 0.76 V.

Silicon nanowire solar cells grown by PECVD
TL;DR: In this paper, radial junctions of hydrogenated amorphous silicon over p-doped crystalline silicon nanowires were grown in a single pump-down plasma enhanced chemical vapor deposition process on glass substrates.

Radial junction amorphous silicon solar cells on PECVD-grown silicon nanowires
TL;DR: An all-in situ strategy to grow SiNWs, via a vapour-liquid-solid (VLS) mechanism on top of ZnO-coated glass substrate, in a plasma-enhanced chemical vapour deposition (PECVD) reactor, and a parametric study designed to shed light on the absorption and quantum efficiency response.

TL;DR: In this article, an all-in-situ approach to fabricate self-positioned/aligned silicon nanowires via an in-plane solid-liquid-solid growth mode was proposed.
