Elucidating PID Degradation Mechanisms and In Situ Dark I–V Monitoring for Modeling Degradation Rate in CdTe Thin-Film Modules

Degradation of gas-phase trichloroethylene over thin-film TiO2 photocatalyst in multi-modules reactor.

The present paper examined the photocatalytic degradation (PCD) of gas-phase trichloroethylene (TCE) over thin-film TiO2. A large-scale treatment of TCE was carried out using scale-up continuous flow photo-reactor in which nine reactors were arranged in parallel and series. The parallel or serial arrangement is a significant factor to determine the special arrangement of whole reactor module as...

Metabolic Biomarkers for Monitoring in Situ Anaerobic Hydrocarbon Degradation

During the past 15 years researchers have made great strides in understanding the metabolism of hydrocarbons by anaerobic bacteria. Organisms capable of utilizing benzene, toluene, ethylbenzene, xylenes, alkanes, and polycyclic aromatic hydrocarbons have been isolated and described. In addition, the mechanisms of degradation for these compounds have been elucidated. This basic research has led ...

TiO2 Thin Film: Preparation, Characterization, and its Photocatalytic Degradation of Basic Yellow 28 Dye

In this research, the thin films of N-S doped titanium dioxide (TiO2) were successfully prepared by simple sol-gel method in the presence of tetrabutylorthotitanate as a starting reagent. Furthermore, titanium dioxide (TiO2) was functionalized with thiourea. Furthermore, N-S doped titanium dioxides (NSTO) were fixed on glass balls by glass balls fixed-bed reactor system. Besides, the effect of ...

Modelling and Degradation Characteristics of Thin-film CIGS Solar Cells

Light-induced Degradation of Thin-film Microcrystalline Silicon Solar Cells

This paper evaluates the stability of a pin and a nip dilution series of microcrystalline silicon solar cells when exposed to white light (AM 1.5-like spectrum). Variation of electrical parameters and defect-related absorption is investigated as a function of light soaking and annealing steps. Cells of medium crystallinity show less than 10% reversible relative efficiency loss after 1000 hours ...
