A research team in Europe has achieved a world record-setting solar conversion efficiency of 44.7 percent, and assuming that higher efficiency translates into lower costs (someday), it’s yet another indicator that we’re only at the beginning of a long decline in the cost of solar power.

Solar (and wind, for that matter) is already competitive with or cheaper than coal in US markets, and with solar cell efficiency edging this close to the 50 percent efficiency mark, we’re expecting to see those trend lines grow farther and faster.
