A change in chemical composition enabled scientists to boost the longevity and efficiency of a perovskite solar cell developed at the U.S. Department of Energy’s (DOE’s) National Renewable Energy Laboratory (NREL). The new formula enabled the solar cell to resist a stability problem that has so far thwarted the commercialization of perovskites.
When I was at Abu Dhabi Ascent earlier this year, I got to speak with Dr. Steve Griffiths, Executive Director of Institute Initiatives at Masdar Institute, about a wide variety of solar power topics. The initial questions I had were regarding Masdar Institute’s solar PV research, but we ended up … [continued]
Another month, another solar record. Here’s a repost from Solar Love regarding the world’s latest solar cell efficiency record: No, this is not a record for all types of solar cells. As you can see in the National Renewable Energy Laboratory (NREL) chart below, multi-junction solar cells take top spot … [continued]
Here’s a great solar PV story from the good folks over at NREL (note that we’ve already covered Solar Junction’s 44% solar cell efficiency record, but this post below goes above & beyond that first one): It takes outside-the-box thinking to outsmart the solar spectrum and set a world record for … [continued]
“Scientists boosted the significance of tandem polymer solar cells by successfully testing cells with low-bandgap polymers that achieved certified conversion efficiencies of 8.62 ± 0.3% with respect to standard terrestrial reporting conditions,” the National Renewable Energy Laboratory (NREL) announced today. “Further, after the researchers incorporated a new infrared-absorbing polymer … [continued]
Some more top cleantech news of the past couple weeks, to go along with the 60+ articles we’ve published. 1. Despite recent/upcoming solar feed-in tariff cuts, UK energy minister Greg Barker announced a ramp-up of the UK’s solar power ambitions last Thursday. Barker thinks the UK will have 4 … [continued]
Solar Junction is a 4-year-old company spun out of Stanford University that designs high-efficiency, multi-junction solar cells for concentrating photovoltaic (CPV) solar collectors. The National Renewable Energy Laboratory recently certified that its solar cells can operate at 40.9% efficiency, a significantly higher efficiency than typical silicon solar cells that … [continued]
