The solar power industry has enjoyed an innovation boom over the last decade or so, with accelerating production capacity and matching price drops. Last year, the industry added some 133 gigawatts (GW) of capacity worldwide, which is almost 19 percent of the previously installed 710 GW of capacity. One GW of power equals the output of 3.125 million solar photovoltaic (PV) panels, according to the US Department of Energy.
Such leaps in global capacity reflect the fact that commercial solar panels are approaching 20 percent efficiency which is near the theoretical limits. What is more, manufacturers are consolidating production methods and creating standards that make it easier to share suppliers.
With such progress alight, it might seem like a time for blue-sky nanomaterials researchers to entrust their promising discoveries to tech transfer professionals and move on to the next theoretical challenge. But physicist Sajeev John of the University of Toronto, one of many materials scientists with a promising new solar cell trick up his sleeve, says, “I wouldn’t say I’m knocking on the door of existing industry. I want to keep the IP [intellectual property] and develop it, rather than just license it to existing solar cell companies.”
John and other researchers are betting that the nanomaterials they are developing, including reimagined silicon photonic crystals and organic photovoltaic materials, are different enough, and valuable enough, to merit new industrial production infrastructure.
