| The idea of photovoltaic cells in the 1960s, but since then the level of scientific research restrictions until the mid-1990s have greater progress. Heat photovoltaic system from thermal radiation, spectrum controller, components of photovoltaic cells, heat recovery and the secondary component composition. Spectrum controller that is optical filter, used to achieve thermal radiation and thermal photovoltaic cells between the optical match, needed a major role through the band infrared light and heat photovoltaic cells can not be converted into electrical energy infrared Light reflection back for re-use of thermal radiation. Controllers direct impact on the spectrum of photovoltaic conversion efficiency of the system, so its research on the technology it is particularly important. This paper on the spectrum controller technology, that is, the surface coating spectrum controller antireflective coating technology research.In this paper, film and into the vacuum coating of theoretical knowledge of the issues identified based on the antireflective film coating method: electron beam evaporation. In determining the use of electron beam evaporation, the analysis of the impact of Si, SiO2, TiO2 these three films growth and structure of the main parameters: the substrate temperature, vacuum and deposition rate, determined through further testing of these three parameters The film performance and structure of the end of the spectrum is the controller of the membrane technology parameters and processes. |
