SOLAR BATTERY AND SOLAR BATTERY MANUFACTURING METHOD

WIPO Patent Application WO/2018/123687

A1

The present invention pertains to a solar battery and a method for manufacturing a solar battery, the purpose being to improve the efficiency of the solar battery by connecting a belt-shaped ribbon (7), which is an external terminal, directly to the top part of a finger electrode (5) and reducing the resistance component. After the finger electrode (5) containing silver and lead is formed on an insulating film (3), and a fixing bar (6) is formed on the insulating film (3) with the finger electrode (5) portion or a portion with room left as an opening, firing is performed. By the action of the silver and lead contained in the finger electrode (5) during firing, the insulating film (3) that is the film below the finger electrode (5) is pierced through, forming an electrically conductive path between a region that generates a high electron concentration when light, etc., is irradiated on a substrate, and the finger electrode (5), and furthermore, simultaneous with the time of firing, due to the action of the glass material contained in the fixing bar (6), the fixing bar (6) is formed on the insulating film (3) firmly adhered and well soldered.
