Semiconducting bismuth sulfide (Bi2S3) nanoplates with unique highly oriented {001} surfaces were prepared on a large scale using a novel organic precursor Bi(DTCA)3 (DTCA = carbazole-9-carbodithioic acid). The as-prepared Bi2S3 nanoplates were dispersed in dimethyl sulfoxide (DMSO) and spin-coated onto an indium tin oxide (ITO) coated glass substrate. With a simple ITO/Bi2S3/Al stacked structu...

Effective coatings improve the performance of any device designed to emit or collect light over a range of angles and wavelengths. Improved broadband and wide angle antireflection coatings (ARCs) are a simple and direct way to improve solar cell performance. In this paper we demonstrate a multilayered ARC optimized using a new meta-heuristic algorithm called the average uniform algorithm (AUA)....

Tin(II) sulfide (SnS) is an attractive semiconductor for solar energy conversion in thin film devices due to its bandgap of around 1.3 eV orthorhombic polymorph, and a band gap 1.5–1.7 the cubic polymorph—both which are commensurate with efficient light harvesting, combined high absorption coefficient (10−4 cm−1) across NIR–visible region electromagnetic spectrum, leading theoretical power effi...

Hybrid nanomaterials where active battery nanoparticles are synthesized directly onto conductive additives such as graphene hold the promise of improving the cyclability and energy density of conversion and alloying type Li-ion battery electrodes. Here we investigate the evolution of hybrid reduced graphene oxide-tin sulfide (rGO-SnS2) electrodes during battery cycling. These hybrid nanoparticl...
