The piezoelectric materials were hybrids of the solar cell in a single panel to harvest more electricity. Through observation, simulations, and experiments, the researchers found that the prototype is capable of harnessing solar energy up to 20 volts when the sun reaches its peak position and 2 volts when there is continuous rain for at least an hour.
