Advantages

Fastest response

Direct collection of photogenerated carriers without interfacial delay results in a decay time of only ~0.011 s at 300 nm.

Self-powered

Photoresponse is obtained at 0 V vs Ag/AgCl, eliminating the need for external bias.

Simple structure

Only a ZnS nanoparticles/FTO structure without other heterojunctions, making design and fabrication easier.
