A photovoltaic device in which a first solar battery unit and a second solar battery unit are stacked between a first electrode and a second electrode and sandwich an intermediate layer having conductivity, wherein
- a Schottky barrier is formed between the intermediate layer and a material which connects the first electrode and the second electrode.
A method of manufacturing a photovoltaic device in which a first solar battery unit and a second solar battery unit are stacked between a first electrode and a second electrode and sandwich an intermediate layer having conductivity, the method comprising:
- a first step in which a groove is formed through the first solar battery unit, the second solar battery unit, and the intermediate layer and reaching a front surface of the first electrode;
- and
- a second step in which a material which connects the first electrode and the second electrode through the groove, and which forms a Schottky barrier with the intermediate layer, is embedded.
