A PHOTOVOLTAIC SYSTEM FOR AN ELECTRONIC APPLIANCE

摘要

This invention relates to a photovoltaic system for electronic appliance. The photovoltaic system comprises an energy concentrator having an outer layer (201) and an inner layer (202), the outer layer (201) adapted to gather incoming electromagnetic radiation into the energy concentrator (101) and the inner layer (202) being adapted for reflecting the incoming electromagnetic radiation such that the incoming electromagnetic radiation becomes concentrated within the energy concentrator (101). The system further comprises a solar cell (102) optically coupled to the energy concentrator (101), such that light concentrated in the energy concentrator is directed to the solar cell, the solar cell adapted to act as a power source for the electronic appliance (103). The outer layer (201) of the energy concentrator (101) forms part of an outer surface of the electronic appliance (103) and the inner layer (202) of the energy concentrator (101) is formed around a cavity for hosting electronic or mechanical components of the electronic appliance (103) and the energy concentrator is configured to reflect light through the energy concentrator (101) around at least a part of the cavity (305).
