The Study On Quality Control In Solar Cell Manufacturing Process Of X Company

The manufacture of solar cell refers to the transformation from silicon wafer to solar cell through the procedure of cleaning, diffusion, PECVD, printing and sintering. The quality control through the manufacture process is the basic factor of improving the production quality and enterprise core competence.Based on the streamlines research of quality control during solar cell manufacture process, the essay has explored a series of method of checking out critical activity and quality control points, analysis quality control issues, developing counter measures and improve products quality, which has provided a live case for manufacturing corporations in optimizing quality control.The essay takes the quality control through the process of solar cell manufacture in X Company as the study object.The essay analyzes quality management status in X company through SWOT, obtains the critical activity and quality control points that affects the product quality via histogram,studies on the way how critical activity and quality control points influences the product quality by means of Cause-Effect Graphs, designs the prevention and control measures according to PDCA, so as to reduce the product quality issues. Main contents of this essay are as follows:1. The research of the importance and urgency of strengthening quality management and improving quality control methods. According to the highlights of the status and tendency of photovoltaic industry and the internal and external factors impacting on the development of X company, put forward a proposal that strengthening quality control is the important mean of persevering themselves,raising product quality and competitiveness in marketplace for solar cell producing enterprises in this very period of reorganization and integration in photovoltaic industry.2. The research of key factors impacting quality in solar cell producing process. The essay takes solar cell producing process of X company as an example, based on the comprehensive analysis of quality management status in X company, the producing process and key quality factors in solar cell manufacture, the main process of manufacture and key point of quality control can be recognized through histogram,4M1E and Cause-Effect Graphs and an analysis and summary is made on the main quality issues in producing process. 3.The study on the design and establishment of Quality improvement plan in solar cell producing process of X company. The essay takes the key producing process,quality control points and main quality issues in solar cell manufacture as research object, designs and establishes the quality control and prevention measures, in order to ensure the solar cells produced by X company achieve intended the quality target and meet the potential demands of its customers.The innovation of the essay lies in the introduction the concept of key points of quality control into daily production of solar cell manufacture enterprises. In this way the enterprises can apply limited resources better in management control of key process and quality control points, reduce the marginal utility and resource waste due to the launch of whole process quality control and promote the production quality in a better way.
