Thin film solar cell
专利汇可以提供Thin film solar cell专利检索，专利查询，专利分析的服务。并且PURPOSE: To obtain a highly efficient device with characteristics resisting against environmental conditions including moisture and contaminated matters by a method wherein an amorphous solar cell in which the division of elements is not difficult is used, increase in number of elements being not related to the increase in quantity of processes and costs.
CONSTITUTION: An electrode in the shape of paste 2 of silver series is printed and calcined on the surface of a glass board 1 constituting the light receiving surface of a solar cell. This electrode 2 is composed of a bus bar portion for connecting the interior portions of light receiving surfaces together and a grid electrode to be connected to both sides. Next ITO transparent material for the electrode is evaporated covering the whole surface of the electrode 2 of the board 1, and the board is etched to produce a pattern desired and form an ITO transparent electrode. After this process, an amorphous silicon thin film 4 is formed, so that an element layer of the solar cell having the structure of n
+ -n
- -P
+ can be obtained. Next an electrode 6 is formed, then the amorphous silicon elements are connected together in series. Thence an organic passivation film 7, lead wire 8, resin layer 9 for protection etc. are provided.
