Solar cell system for outputting an audio signal
View Patent ↗Disclosed herein is a solar cell system including: a plurality of power generation panels that differ in the range of wavelengths of light they absorb from each other and convert light into power; a voltage detection section adapted to detect the voltage of power generated by each of the plurality of power generation panels; a reproduction section adapted to compare the voltages of the plurality of power generation panels detected by the voltage detection section so as to reproduce an audio or music signal appropriate to the comparison result; and an output section adapted to output audio or music reproduced by the reproduction section.
1. A solar cell system comprising:
a plurality of power generation panels each configured to absorb light in a range of wavelengths different from other of the plurality of power generation panels and convert light into power;
a voltage detection section configured to detect voltages of the power generated by the plurality of power generation panels;
a reproduction section configured to compare the detected voltages of the power generated by the plurality of power generation panels, and reproduce an audio signal based on the comparison; and
an output section configured to output the audio signal reproduced by the reproduction section,
wherein the output section comprises one or more piezoelectric elements that each expand or contract in response to a voltage applied thereto, and
the one or more piezoelectric elements output the audio signal by vibrating the plurality of power generation panels.
2. The solar cell system of claim 1 , wherein the reproduction section identifies a current spectra of sunlight by comparing the detected voltages of the plurality of power generation panels and reproduces an audio or music signal associated with a current time zone determined based on the identification.
3. The solar cell system of claim 1 , further comprising
a power storage section adapted to store power generated by the plurality of power generation panels.
4. A solar cell system comprising:
