Preparation and photoelectric performance of ITO/TiO2/CdS composite thin films

Immobilization of horseradish peroxidase in three-dimensional macroporous TiO2 matrices for biosensor applications

“…At the beginning of illumination, the photogenerated electrons are first injected into the surface states with a shallow energy level followed by quick transfer to the surface states with a deep energy level. When the surface states with the deep energy level are fully filled, the capture and release of electrons at the shallow energy level surface states reaches homeostasis, and the photocurrent maintains a constant value [21]. The current decreased from −150 nA without illumination to −330 nA under UV pulsed-illumination.…”

Growth dynamics of polyamidoamine dendrimer encapsulated CdS nanoparticles

“…CdS is for instance a type II-VI semiconductor widely employed in photocatalysis [5][6], sensor design [7][8], non linear optic materials [9][10], optoelectronic devices [11][12] and photovoltaic applications [13][14][15].…”

ZnO/CdS Bilayer used for Electrode in Photovoltaic Device

“…In this way, the charge separation is achieved [16]. The redox couple in the electrolyte, after reducing the oxidized dye, can be renewed in the counterelectrode, making the photoelectrochemical cell regenerative [5]. It is clearly seen that the coupling of ZnO with CdS can significantly enhance the separation of the electron and hole pairs, therefore, ameliorate the photoelectric performance of the ZnO/CdS bilayer films.…”

“…Among the various semiconductors, CdSe, CdTe, CuInS 2 , InP, etc, are used as sensitizers . [4], CdS has shown much promise as an effective sensitizer [5]. It is the most widely studied nanocrystalline semiconductor as a photoanode in photoelectrochemical cells because of its suitable band gap, long lifetime, important optical properties, excellent stability and ease of fabrication [6].…”
