PURPOSE:To obtain a solar battery of high conversion efficiency at a low cost by avoiding the increase of the series resistance by a method wherein conductive paste containing carbon and a metal is applied, while setting the seat resistance at 10OMEGA/square or less, and thereafter said paste is hardened, when an electrode made of Si is formed. CONSTITUTION:A clear electrode made of ITO, etc. is adhered on a glass substrate 1, and a P type layer 3, an I-type layer 4, and an N type layer 5 made of amorphous Si are formed theren by SiH4 glow discharge decomposition into a solar battery. Next, the electrode 6 is adhered on the layer 5; said electrode is formed by applying and hardening the conductive paste containing carbon and mercury as the main component, and the seat resistance is prescribed at 10OMEGA/ square or less. Thus, the contact resistance also becomes small, and accordingly the solar battery of high conversion efficiency can be obtained. Here, not only Ag but also Cu, Au, Al, Ni, etc. is available as the metal material. |
