Sentences with phrase «said solar cell efficiency»

Calisolar said solar cell efficiency was «increasing to 16.8 % on average this year on our way to 17 %.»

Not exact matches

«We are excited to expand our partnership with Panasonic as we move towards a combined Tesla and SolarCity,» said Tesla CTO and co-founder with Musk, JB Straubel, who added that the partnership with Panasonic will allow for accelerated production of solar cells and modules at the best possible cost and at high efficiency and reliability.

For example, current silicon - based solar cells convert realistically only about 25 percent of sunlight into electricity, so efficiency is an issue, says Calley Eads, a fifth - year doctoral student in the UA's Department of Chemistry and Biochemistry who studies some of the properties of these new materials.

«In theory, conventional single - junction solar cells can only achieve an efficiency level of about 34 percent, but in practice they don't achieve that,» said study co-author Paul Braun, a professor of materials science at Illinois.

«As we continue to work on enhancing the performance and efficiency of the solar cells, we also look forward to opportunities to collaborate with industry in order to develop this technology further,» Yang said.

«In perovskite solar cells and LEDs, you tend to lose a lot of efficiency through defects,» said Dr Sam Stranks, who led the research while he was a Marie Curie Fellow jointly at MIT and Cambridge.

If this asphalt and concrete were replaced with solar cells of moderate efficiency — around 15 per cent — they would not only generate a significant amount of energy but would also provide a backbone infrastructure to deliver the energy to our doors, he says.

«The use of tiny cells for efficiency testing has prompted some to question comparison of perovskite solar cells with other established photovoltaic technologies,» said Nitin Padture, professor of engineering at Brown, director of Brown's Institute for Molecular and Nanoscale Innovation, and one of the senior authors of the new research.

«Our new approach can lower the operating temperature of solar cells passively, improving energy conversion efficiency significantly and increasing the life expectancy of solar cells,» said Linxiao Zhu, a physicist at Stanford and lead author on the Optica paper.

Group leader Hikaru Kobayashi says, «Making very high efficiency solar cells is important but we should also consider the economics and practicality of any processes used to increase efficiency.

People didn't take electrical solar cells — which are now about 24 percent efficient — seriously until scientists brought efficiency up to 10 percent, so Caltech may have reached a threshold to make people start paying attention, Cronin said.

That said, it isn't clear if it's even possible for rooftop arrays to power an entire car given the efficiency of current solar cells and the limited surface area on a vehicle.

UPDATE A commenter wondered about the efficiency of Solyndra's solar modules: Solyndra says that its solar cells can convert 12 - 14 % of the sunlight hitting them into electricity.

So far the nanopillar solar cells have been shown to have an efficiency of about 6 %, but the researchers say that further improvements are possible.

«If the material can be synthesized so that only very efficient facets develop, then we could see a big jump in the efficiency of perovskite solar cells, possibly approaching 31 percent,» said Sibel Leblebici, a postdoctoral researcher at the Molecular Foundry.
