Seems unlikely that solar cells would work at night, but scientists of Idaho National Laboratory are ”hunting down” the magic formula. It’s about new breed of nanoscale light-sensitive antennas that could make this work! Mr. Novack from INL declares that new devices have the ability to harvest infrared radiation. About half of the solar energy is to be found within the borders of IR spectrum. IR is re-emitted by the Earth surface also after sunset, therefore antennas can capture energy during night time.
