X-ray ,which is excited from the X ray tube, has one wavelength scope, that is energy scope. According to the elements to be analyzed, X ray is choused by filter, and reach the sample. Atoms in the sample will absorb the X ray energy and the decay to emit the special x ray. The X ray will be collected by the collimator into the detector active area, and transferred into electron signal, the signal also will be processed in to energy spectrum and related concentration data by pulse processor with software.

Based on a variety of books and materials, foreign or domestic, this thesis deals with the recent development and application, the past, present and future for solar energy and solar cells, analyzes the great senses of solar energy and solar cells for the development of economic, and analyzes their structure photovoltaic effect and conservation efficiency. The writer also elaborates the working principles and application characteristic of solar cell, various factors that may lead to bad conservation efficiency of solar cell. Based on the the working principles and application characteristic of solar cell, emphasizes on some ways of improving photovoltaic conservation efficiency for solar cell, for example: the appropriate thickness of solar cell, the low resistance, the phalanx of solar cell, the film of reduce the reflect of solar rays, and so on, and designs simply the feasible way, then give out the CAD frame chart .
