Research presented at Symposium P of the 10th International Conference of Materials and Advanced Technology (ICMAT 2019)
Goutam Dalapati, Lydia Wong and Frank Osterloh introduce the Journal of Materials Chemistry A themed collection on Research presented at the ICMAT 2019 symposium.
Rapid advances in antimony triselenide photocathodes for solar hydrogen generation
The advantages of antimony triselenide (Sb2Se3) over other semiconducting materials for solar-to-hydrogen conversion are highlighted. Rapid recent advances in Sb2Se3 photocathode technology are summarized and future research directions are discussed.
Influence of sodium diffusion from substrates on performance of SnS/CdS thin-film solar cells
The influence of Na diffused from substrates on SnS/CdS thin-film solar cells was investigated.
Paper
The role of ultra-thin MnOx co-catalysts on the photoelectrochemical properties of BiVO4 photoanodes
MnOx suppresses surface recombination by enhancing band bending on BiVO4, but direct contact with the FTO substrate provides shunting pathways.
Eco-friendly quantum dots for liquid luminescent solar concentrators
Eco-friendly Cu doped Zn–In–Se QDs for liquid luminescent solar concentrators can provide a platform of more efficient and environmentally friendly solar energy harvest systems.
Beyond 10% efficiency Cu2ZnSnS4 solar cells enabled by modifying the heterojunction interface chemistry
ZnCdS buffer layers deposited from high concentration ammonia enable a less defective interface and over 10% efficiency Cu2ZnSnS4 solar cell.
Effect of Cd on cation redistribution and order-disorder transition in Cu2(Zn,Cd)SnS4
The difference in the order-disorder transformation leads to a reduction in atomic disorder in Cu2CdSnS4 as compared to Cu2ZnSnS4.
Paper
Plasma assisted vapor solid deposition of Co3O4 tapered nanorods for energy applications
Self-standing, 1-dimensional (1D) structures of p-type metal oxide (MOx) have been the focus of considerable attention, due to their unique properties in energy storage and solar light conversion.
Controlled synthesis of (hk1) preferentially oriented Sb2Se3 rod arrays by co-evaporation for photovoltaic applications
In this paper, we propose that the microstructural control of (hk1) preferentially oriented Sb2Se3 films from flat films to rod arrays can improve their photovoltaic efficiency by maximizing the carrier transport characteristics.
Nano-scale sulfurization of the Cu2ZnSnSe4 crystal surface for photovoltaic applications
A new and effective method for nano-scale sulfurization of the Cu2ZnSnSe4 crystal surface was developed.
Flexible high-efficiency CZTSSe solar cells on stainless steel substrates
Stainless steel (SS) foil is made of abundant materials and is a durable and flexible substrate, but the efficiency of a solar cell on SS foil deteriorates via the diffusion of impurities from the SS substrate into a Cu2ZnSn(S,Se)4 (CZTSSe) absorber layer.
The effect of Ag alloying of Cu2(Zn,Cd)SnS4 on the monograin powder properties and solar cell performance
The reported results confirm that the positive effect of Ag in (Cu1−xAgx)1.85(Zn0.8Cd0.2)1.1SnS4 MGL solar cells appears only at very low Ag concentrations (x ≤ 1%).
Effects of S and Se contents on the physical and photovoltaic properties of Cu2ZnSn(SX, Se1−X)4 thin films: achieving a PCE of 9.47%
CZTSSe thin films with various S/(S + Se) compositions were synthesized by adding SeS2 powder in an optimized selenization process.
