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 high output voltage by using single substrates, by the method wherein, by utilizing the fact that the thickness of a thin film solar cell is small and consequently the sheet resistance is high, a semiconductor material is not separated, only the electrodes provided on this are separated, and these are connected in series. CONSTITUTION:On glass substrate 4, which combines the function of a light receiving surface material in a solar cell package, transparent conducting films 7 of In2O3- SnO2, which are to become electrodes, are formed at fixed intervals by electron beam evaporation. Next, the entire surface including these is coated with amorphous Si layer 5 of p n p , having the function of pn junction. On top of this and corresponding to conducting films 7, electrodes 6 of Al are arranged at the same intervals. Subsequently, these electrodes 6 are connected in series, and light is introduced on the side of conducting films 7. By this, since the sheet resistance of Si layer 5 is extremely high, there is no need for dividing this, so that it is possible to obtain a high output voltage while the series resistance loss is reduced by means of the series connection of electrodes 6 only.，下面是Thin film solar cell专利的具体信息内容。
