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 […]

A cleantech revolution is taking place in the USA

I really enjoy infographics as they enable to gather a lot of information in a few moments. The latest I found via Twitter (see left) is on how a cleantech revolution is already taking place in the United States of America. Indeed, since 2007, energy efficiency, renewables like solar and wind (as well as natural
