Its basic principle is use photovoltaic effect to solar radiation energy to electric immediate. Its foundation appliance is solar cell. Solar cell is a system make of silicon wafers. The quality of silicon wafer influences the photoelectric conversion efficiency of solar immediate. This passage introduced the current situation and trend of Photovoltaic Industry. We have a general introduce of multiwire cutting , the operating principle and the structure of silicon wafer slitter. Also it included the expound silicon wafer cutting and technological process in detail. At last, we have a detail expound of the problems and solve project while cutting silicon wafers and solve project. . Keywords: multiwire cutting; 目 录摘要 I Abstract II 第1章 光伏产业的发展现状及趋势 1 1 .1国际光伏产业的现状 1 1 .2国内光伏产业的现状 1 1 .3 未来的发展趋势及展望.................................................................................1 第2章 多线切割 3 2 .1 多线切割技术的发展历史 3 2 .2 多线切割机的基本介绍 3 2.3 中国太阳能硅片线切割设备国产化的现状和趋势....................................3 第3章 硅片切割机的工作原理及结构 5 3 .1 基本结构 5 3 .2 工作原理 5 第4章 硅片切割工艺及流程 10 4 .1切割工艺 10 4.1.1主要参数..............................................................................................11 4.1.2切割液的(PEG)粘度............................................................................11 4.1.3碳化硅微粉的粒型及粒度砂浆的粘度砂浆的流量钢线的速度钢线的张力工件的进给速度4 .2 主要操作流程 10 4.2.1hct
