Solar cell and portable electronic device

摘要

A solar cell and a portable electronic device are provided. The solar cell includes a semiconductor material configured to absorb light for generating a current. The solar cell further includes a positive contact and a negative contact. In addition, the negative contact is configured to couple with an external interface. The portable electronic device includes an energy storage unit. The portable electronic device also includes a semiconductor material configured to absorb light for generating a current, a positive contact, and a negative contact. The negative contact of the portable electronic device is configured to couple with an external interface.

主权项

1. A solar cell comprising:
a semiconductor material configured to absorb light for generating a current, the semiconductor material having a positive side and a negative side, the positive side comprising an inward facing side and the negative comprising an outward facing side; a positive contact in electrical communication with the positive side, the positive contact configured to collect a light induced current from the positive side; and a negative contact in electrical communication with the negative side, and located on the outward facing side, the negative contact configured to collect the light induced current from the negative side, the negative contact having a coil geometry configured to couple with an external power charging interface to generate inductive current in the negative contact, and an external near field communication device to receive data therefrom, the positive contact and the negative contact further configured to connect with an energy storage unit to convey the light induced current there to, and the negative contact further configured to: connect to the energy storage unit independent of the positive contact to convey the induction current thereto; and communicate the data received from the external near field communication device to a data processing device.
