I've looked into the issue of ultra high energy efficiency conversion solar before, and found an interesting design called the multi tower solar array (MTSA). It's a fresnel multi tower design that captures about 90 percent of the available beam, and focuses that onto a reveiver. The receiver is divided into two parts, one thermal, one PV wavelengths. The beam is split by a beam splitting coating. PV on the top, a heat engine on the bottom.
Another promising option is infrared nano-antenna technology. Up to 80 percent conversion efficiency could be achieved. Because the design converts infrared - heat - it could use cheap thermal storage to produce a longer portion of the day.
