Solar singlet fission bends the laws of physics to boost solar power efficiency by 30%

2014-07-11 17:27:46| Extremetech

Chemists at the University of California Riverside (UCR) have devised a way of increasing solar cell efficiency by as much as 30%. With current photovoltaic cells unable to surpass 33% due to the Shockley-Queisser limit, a boost of 30%, to a total efficiency of 60% or more, would be absolutely huge -- and exactly what solar power needs if it ever hopes to be a cost-efficient alternative to fossil fuel power generation. Best of all, though, this new method for boosting solar cell efficiency has an awesome name: singlet fission.

California Drought Proves Laws of Nature Absolute

EcoWatch: One peril of being human is that we often respond poorly to crises. I`m sure we all have examples--personal to global--where the heat of the moment pushed us in the wrong direction. Because we now face one of the worst droughts in California history, the stage is set to flirt with error on a scale as colossal as the crisis itself. The House of Representatives, for example, passed H.R. 3964 in February to indiscriminately move additional northern California water southward, to abandon restoration...
