As perovskite solar cells set efficiency records and the nascent technology becomes more stable, another major challenge remains: the issue of scalability, according to researchers at the Department of Energy’s National Renewable Energy Laboratory (NREL). “It is scalable,” said Kai Zhu, a materials science researcher at NREL. “We just needRead More

Over the past decade, perovskites have rapidly evolved into a promising technology, now with the ability to convert about 23 percent of sunlight into electricity, but work is still needed to make the devices durable enough for long-term use. Researchers at the U.S. Department of Energy’s National Renewable Energy LaboratoryRead More

Perovskite solar cells are the most tantalizing research category in the solar industry because of their efficiency and versatility, but thus far haven’t budged outside a lab setting. A microscopic analysis conducted by the Department of Energy’s National Renewable Energy Laboratory has revealed new insight into how the devices degrade— huge information forRead More

The solar industry is forever in need of constant innovation and scientific breakthrough. Even now, with PV capacity reaching record highs, prices continuing to fall and efficiencies inching up, more innovation is needed. A lot more. (Not to mention whatever fallout is felt in the module market following the SectionRead More

Scientists at the U.S. Department of Energy’s (DOE) National Renewable Energy Laboratory (NREL) developed a new perovskite ink with a long processing window that allows the scalable production of perovskite thin films for high-efficiency solar cells. Proven highly efficient at converting sunlight into electricity, perovskite solar cells have yet toRead More

In our worst Seinfeld impersonation voice we ask, “what’s the deal with perovskite solar cells?” The National Renewable Energy Labratory (NREL) answers us by noting that a strategy for producing stable and commercially available perovskite solar cells (PSCs) has been proposed by Kai Zhu and Keith Emery in collaboration with Nam-Gyu Park (Korea), MichaelRead More

UCLA professor Yang Yang, member of the California NanoSystems Institute, is a renowned innovator of solar cell technology whose team in recent years has developed next-generation solar cells constructed of perovskite, which has a decent efficiency converting sunlight to electricity. Despite this success, the delicate nature of perovskite — a veryRead More

Perovskite solar cells have shown potential both in the rapid efficiency improvement and in cheap material and manufacturing costs, says IDTechEx. Just how rapid of an efficiency improvement? Perovskite cells went from 2.2% in 2006 to the latest record 20.1% in 2014. They have attracted attention from the likes of DSSC and OPVsRead More
