I still think the most promise lies in concentraing the light and heat from the sun in a large satellite-dish type device and using it to turn a Stirling engine to power a generator or charge a deep-cell battery. The loss of efficiency is far less than the conversion of light.

Aeronutronic did this during the 70's and put it up at Edwards AFB. Oil got cheaper. Don't know what happened to experiment.
