专利汇可以提供Thin film solar battery专利检索,专利查询,专利分析的服务。并且PURPOSE:To enhance application efficiency of substrate and prevent increase of series resistance between electrodes even in the large scale structure condition by providing in parallel the transparent electrodes with a constant interval on the one main surface of photo-electric conversion thin tilm while the electrodes opposing thereto on the other main surface and by connecting both electrodes with the diffusion layers in the thin film. CONSTITUTION:The transparent electrodes 21' are provided in parallel with a constant interval on the glass substrate 20 and an Al layer 22 is evaporated at part thereof in order to form a substrate. An amorphous Si thin film 23 is deposited thereon in the sequence of the P, I and N layers. During deposition, the thin film 23 is diffused and a low resistance region 24 is formed. When an Al 25 is provided on the surface and it is connected to the region 24, the Al 25 will become the rear side electrode of the adjacent element in combination with the series connection between the elements. The electrodes 26, 27 are provided to the elements in both sides and these are formed as the serially connected elements. According to this structure, an independent single solar battery can be serially connected with the minimum connecting distance and thereby application coefficient of substrate can be remarkably improved.,下面是Thin film solar battery专利的具体信息内容。
