Abstract
CIS/CdS solar cell is called CIS cell for short,CIS film is its kernel ,decides its nature, My work is studying how to fabricate CIS film,which can produce good cells. Using evaporation technological process ,we tried and than one year later,some questions were resolved. Both the end production ratio and controllability 盯e greatly

area,being on the
In this thesis,CIS/CdS solar cell's characters are checked .The facts inf1uencing the
efficiency ofthe CIS cells are carefully analyzed; The effect ofMo layer,Se sources,big areas of grid and all kinds of evaporation process to CIS films are studied and describ时, How to fabricate little ceIJs to make good cells are put forward; The nature and effect of CdS are analyzed; the keys of processing ,the important parameter 缸ld its judging criterion
were summarized systematically and fully detailed. Comparing our cell dates with foreign's, 1 explain our cell's special heat treating phenomenon
Finally,the present question and the 岛ture work of the CIS solar cells were discussed
