Title:
PHOTOVOLTAIC DEVICE, AND ITS MANUFACTURING METHOD
Document Type and Number:
Japanese Patent JP2007317840
Kind Code:
A
Abstract:

To provide a photovoltaic device where connection reliability of a solder electrode is improved, and to provide a manufacturing method of the device.

In the photovoltaic device 1, an outer peripheral end of a second electrode 16 formed of solder is positioned on an inner side compared to an outer peripheral end of a first electrode 15 formed of conductive paste. To put it concretely, a periphery of the first electrode 15 is covered with an insulating layer 14, and only vicinity of the center of the first electrode 15 is exposed from the insulating layer 14. The second electrode 16 formed of solder is formed on an upper face of the center of the first electrode 15 which is not covered with the insulating layer 14. Thus, a position shape of the second electrode 16 formed of solder is regulated by the insulating layer 14 covering the periphery of the first electrode 15. Consequently, the outer peripheral end of the second electrode 16 is positioned on the inner side compared to the outer peripheral end of the first electrode 15.
