Combined ZnO nanorod hygrometers and DSSCs for IOTs application

In this study, one-dimensional ZnO nanostructure (ODZN) hygrometers with DSSCs were fabricated on ITO glass substrate. The device combined with hygrometers and DSSCs revealed same characteristics like the pure-ZnO nanorod hygrometer. Results from I-V measurement showed that DSSCs can be applied to ODZN hygrometers to form a self-powered (SP) optoelectronic devce that has useful for IOTs utilizations.
