Breakthroughs in Solar Energy Production

From the website io9:

Solar cell efficiency is nearing 50%. Australian scientists have set a new record by converting more than 40% of sunlight that hits solar panels into electricity. These panels could eventually be mounted on roofs, which current have a 15-18% efficiency rate. And in Germany, scientists converted 46% of light into electricity in a lab, a new record for PVC efficiency.
