Title: Solar cell
Inventor: MORI TAKAHIRO
IPC: H01L31/04
Filed: 1992-12-28
Abstract: PURPOSE:To obtain a solar cell having high photoelectric conversion efficiency and high reliability by specifying a mean particle size of electrodeposition resin at the time of emulsion or suspension. CONSTITUTION:Electrodeposition resin 109 is used to insulate a pinhole, a short- circuit or shunt part 110 occurring due to a spikelike defect of a grain boundary, a substrate 101 or a lower electrode 102 or other cause. That is, a defective part is covered with the resin 109 in which mean particle size at the time of emulsion or suspension is 0.2-10mum. Thus, since impregnation or adsorption of moisture to the defective part is strongly suppressed thereby, deterioration of solar cell characteristics is largely improved as a using time in the case of practical use is elapsed. Further, in the case of a solar cell in which a grid electrode is provided on an upper electrode, since a defective part is covered with electrically insulating resin, a large shunt is eliminated by electrically directly connecting the defective part to the grid electrode.
