STUDY ON Ni-Cr SYSTEM SOLAR SELECTIVE THIN FILMS PREPARED BY MAGNETRON REACTIVE SPUTTERING PROCESS H.Shen1,B.W.Wang1 (1.Guangzhou Institute of Energy Conversion,The Chinese Academy of Sciences,Guangzhou 510070,China) Abstract:Ni-Cr System solar selective thin solid films were prepared by d.c. magnetron reactivesputtering under the atmosphere of O2 and N2. Ni-Cr alloy was chosen......
& Solar Cells, 1995, 37(1): 93-118. [15] DIATEZUA D M, THIRTY P A, DEREUX A, et al. Silicon oxynitride multilayers as spectrally selective material for passive radiative cooling applications [J... as 111-133 nm have high IR transmission across the full 8-13 μm band and highly blocking in the solar spectral region elsewhere, which indicates that Te films thickness in this region can be used as good......

), 13.0% n-pentanol and 24.0% aqueous phase was investigated and chosen for the preparation of cobalt ferrite nanoparticles. Then silicon dioxide was coated onto the surface of the magnetite nanoparticles... for the peaks of CoFe2O4, and imply that the coated silicon dioxide is amorphous. IR absorption spectra of the samples show the characteristic bands of Si-O-Si group and Fe-O group. SEM-EDS indicates......
Simulation and prediction in laser bending of silicon sheet WANG Xu-yue, XU Wei-xing, XU Wen-ji, HU Ya-feng, LIANG Yan-de, WANG Lian-ji Key Laboratory for Precision and Non-traditional Machining... silicon sheet (0.2 mm in thickness) was investigated with JK701 Nd:YAG laser. The models were developed to describe the beam characteristics of pulsed laser. In order to simulate the process of laser......
