PHOTOVOLTAIC ELEMENT AND FABRICATION METHOD THEREOF
First Claim
1. A photovoltaic element which has a photoelectric conversion layer and a collector electrode provided on at least one surface of the photoelectric conversion layer, said photovoltaic element characterized in that a collector electrode covering layer is provided for covering a surface of the collector electrode provided on said at least one surface of the photoelectric conversion layer;
- a tab electrode for electrical connection to an exterior electrode is provided, through said collector electrode covering layer, on a top surface of the collector electrode;
a portion of the collector electrode covering layer that lies between said tab electrode and the collector electrode comprises a solder layer; and
another portion of the collector electrode covering layer that covers a lateral surface of the collector electrode comprises a thermosetting resin layer.

Abstract
A photovoltaic element is obtained which allows use of a low-melting solder and can suppress reduction in reliability and output thereof due to mechanical stress or water intrusion.
The photovoltaic element has a photoelectric conversion layer and a collector electrode provided on at least one surface of the photoelectric conversion layer. Characteristically, a collector electrode covering layer for covering a surface of the collector electrode is provided and a tab electrode for electrical connection to an exterior electrode is provided on a top surface of the collector electrode through the collector electrode covering layer. A portion of the collector electrode covering layer that lies between the tab electrode and collector electrode comprises a solder layer and another portion of the collector electrode covering layer that covers a lateral surface of the collector electrode comprises a thermosetting resin layer.
