It would have been less efficient than the thermal panels used for heating. His device used thermocouples which are used in lots of temperature measuring devices. Many propane/natural gas fireplaces use a stack of thermocouples to turn on the gas but only if the pilot is burning. So NO, theremocouples are not solar cells and use an entirely different and much less efficient technology.
