PURPOSE:To enable to prevent a solar battery module from reduction of electrically insulating performance according to inferiority and deterioration of the junction face even when the module is used outdoor for a long period by a method wherein an uneven part is formed on the glass plate of a region to surround the solar battery element of the module to assemble the element between the glass plate and an electrically insulating plate. CONSTITUTION:The uneven part 14 is formed on the junction face of the glass plate 13 as to surround the solar battery element 11, and the electrically insulating plate 12 is joined applying adhesives. The uneven part 14 is formed by the sand blast process, the etching process or by the method to fusion weld by heating low melting temperature glass paste 17 containing high melting temperature inorganic filler powder 16, etc. A frame body 15 manufactured of aluminum is equipped to the circumference of the insulating plate 12 and the glass plate 13, the frame body 15 thereof has the U-shaped section to enable to hold from both the sides, adhesives are applied to the inside of the frame body 15, the adhesive layer 18 is made to exist between the frame body 15 and the electrically insulating plate 12, the glass plate 13, and junction intensity is enhanced and the module is prevented from invasion of humidity. |
