SOLAR BATTERY POWER COLLECTING SHEET AND SOLAR BATTERY MODULE

摘要

PROBLEM TO BE SOLVED: To prevent invasion of moisture to an insulating layer constituting a power collecting sheet.SOLUTION: A solar battery power collecting sheet includes: wiring 12 that is arranged on a light non-reception surface side of a back contact type solar battery element as internal wiring in a solar battery module, formed on the front surface of a resin substrate 11, and constituted by a conductive body; an insulating layer 13 formed to cover the wiring 12; and a sealing material layer 14 formed on the insulating layer 13. Continuity recessions 16 where the wiring 12 is exposed in order to attain continuity between electrodes on the light non-reception surface side of the solar battery element and the wiring 12 corresponding to the electrodes are formed via the insulating layer 13 and the sealing material layer 14 in the insulating layer 13 and the sealing material layer 14 on the wiring 12. End surfaces of the insulating layer 13 are covered with the sealing material layer 14. It is indispensable that the sealing material layer 14 has a shape to cover the insulating layer 13. Besides, a module end surface sealing shape with the use of a sealing material is simultaneously covered, by which even the invasion of moisture from the side surface of the resin substrate 11 adhering to the insulating layer 13 is prevented.
