Quantum Solar Power Corp. recently reached a milestone in developing a new solar technology that it says will drastically reduce the cost per watt of solar and help it to achieve grid parity with coal-fired plants.
The company announced this week that it has developed a functional prototype of its new absorption layer that leaves out expensive rare Earth elements like Gallium and Tellurium. Those elements keep traditional solar photovoltaic and thin-film technologies from being scalable, Quantum spokesman Erik Cathcart said
The prototype has reached a performance threshold that makes it suitable for testing at the National Renewable Energy Laboratory in Golden, Colo.
The NREL research will verify Quantum’s credibility and lend the company validity in the solar marketplace. It will also provide proof of concept for potential manufacturing partners, Cathcart said.
