Graphene could bring solar PV efficiency to 60%

According to TreeHugger, graphene could offer 60% solar cell efficiency if it were to replace silicon in PV panels. As they note : ” Researchers from the Institute of Photonic Sciences in Spain have just published results from their experiments.” ” While their results so far will probably be more useful to make better image… Continue reading Graphene could bring solar PV efficiency to 60%

Will molybdenite be better than graphene ?

As CleanTechnica recently noted : ” A serious challenger has emerged to take on graphene’s title as the miracle material of the 21st century, and that is a common, silvery looking mineral called molybdenite. (…) The lead researcher asserts that compared to conventional silicon transistors, a molybdenite transistor would use about 100,000 times less energy… Continue reading Will molybdenite be better than graphene ?

Graphene can be produced by sugar

I once wrote that aerogel – a great insulating material, 37 times more insulating that fiberglass – can be made of rice husks, a common byproduct of the most eaten cereal in the world. Now it seems that graphene – a highly conductible and resistant material that could literally revolutionize electronics and computers – can… Continue reading Graphene can be produced by sugar
