Title: Master plate for solar cell board
Inventor: NARUTANI SATORU
IPC: H01L31/04
Filed: 1984-01-31
Abstract: PURPOSE:To obtain the preferable surface conditions at low cost by performing skin-pass rolling after forming a plated layer with a stainless steel thin plate as a core plate. CONSTITUTION:An Ni and/or Cr plated layer is formed on a stainless steel thin plate as a core plate. Consequently, when using it for a solar cell, the cell characteristics can be maintained to be stable for a long term. However, regarding Al, Ag or Cu, the elements cause diffusion in an amorphous layer during usage as a cell and there is possibility of deterioration of the cell characteristics. Meanwhile, Ni and Cr do not cause such phenomenon. Next, the core plate on which the above plated layer is formed is subjected to skin-pass rolling to form a smooth surface. Thus the preferable surface conditions for a parent material for solar cell board can be obtained at low cost.
