The paper reports on the effects of a proton irradiation campaign on a series of thin-film silicon solar cells (singleand double-junction). The effect of subsequent thermal annealing on solar cells degraded by proton irradiation is investigated. A low-temperature annealing behaviour can be observed (at temperatures around 100 to 160 C) for microcrystalline silicon solar cells. To further explor...

Thin alumina films, deposited at 280~ by low-pressure, metal-organic, chemical-vapor deposition on stainless steel, type AISI 304, were annealed at 0.17 kPa in a nitrogen atmosphere for 2, 4, and 17 hr at 600, 700, and 800~ The effect of the annealing process on the adhesion of the thin alumina films was studied using a scanning-scratch tester, type SST-IO1, developed by Shimadzu. The best mech...

A simple process is developed to curl graphene membranes through thermal annealing. The resulting curled graphene ribbons displayed enhanced photocurrent response compared to flat graphene ribbons. The annealing temperature, the thickness of the graphene, and the type of polymethyl methacrylate used were the three key factors that influenced the morphology of graphene during thermal annealing. ...

Organo-metal halide perovskites have suffered undesirably from structural and thermal instabilities. Moreover, thermal annealing is often indispensable to the crystallization of perovskites and removal of residual solvents, which is unsuitable for scalable fabrication of flexible solar modules. Herein, we demonstrate the non-thermal annealing fabrication of a novel type of air-stable triple-cat...

Zinc Sulfide (ZnS) thin films were deposited on glass substrates at the pressure of 10-6 mbar by thermal resistor evaporation technique. The effects of annealing on the structural, optical properties of ZnS films were studied. Crystalline ZnS films have been analyzed by X-ray diffraction. Only cubic phase with the preferred (111) plane was found in ZnS films. Optical characteristics were studie...

In the present work, cupric oxide (CuO) films were obtained through thermal annealing of the copper (Cu) films deposited on quartz substrates by DC magnetron sputtering method. The annealing was performed in air atmosphere for different times ranging from 60-240 min at temperature of 400 ºC. The influence of annealing times on structural and morphological properties of the films was investi...

We propose the use of thin Ag film deposition to remedy the degradation of near-infrared (NIR) absorption of black Si caused by high-temperature thermal annealing. A large amount of random and irregular Ag nanoparticles are formed on the microstructural surface of black Si after Ag film deposition, which compensates the degradation of NIR absorption of black Si caused by thermal annealing. The ...

Etched tracks of apatite and zircon are both widely used for the determination of the thermal history of Earth’s crust. The present understanding of the annealing process is largely limited to mathematical fits to data for etched track-lengths as a function of temperature and time. Details of the annealing of unetched, latent tracks at the atomic scale have remained elusive, as the original tra...
