Abstract
Electrical energy generation apparatuses, in which a solar battery device and a piezoelectric device are combined in a single body by using a plurality of nano wires formed of a semiconductor material having piezoelectric properties.
Claims26
An electrical energy generation apparatus, comprising:
- a first electrode;
- a plurality of nano wires on the first electrode, wherein the plurality of nano wires are formed of a semiconductor material having piezoelectric properties;
- a semiconductor layer forming a p-n junction with the plurality of nano wires, wherein the semiconductor layer is on the first electrode and covers lower parts of the plurality of nano wires;
- a second electrode on the semiconductor layer, wherein upper parts of the plurality of nano wires are exposed via the second electrode;
- and
- a third electrode forming a Schottky contact with the exposed upper parts of the plurality of nano wires.
