This paper first provides an overview about the past 10 years of crystalline silicon solar-cell market development in detail and clarifies that the crystalline silicon solar cell plays a very important role in photovoltaic power generation field. Then various factors affecting the cost and efficiency of crystalline silicon cell module are considered, and the various factors influencing the crystalline silicon solar-cell power generation cost are analyzed in detail. For the crystalline silicon solar-cell module production process, although the package cost accounts for the largest proportion, the reduction in cost of module mainly depends on the improvement of the technical level, such as silicon ingot growth, slicing and cell manufacture. For the production process of the basic elements, reducing the raw materials cost for module manufacture and improving the processing technology continuously will be the basic approach to reduce crystalline silicon-cell cost. Finally, combined with the new technical reports about crystalline silicon solar cell, from the perspective of production process and efficiency-enhancing techniques, the development trends of crystalline silicon-cell module manufacturing technology in the future are prospected.
