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%

Sharp presents transparent solar panels

To Engadget : ” Sharp has announced an unusual photovoltaic panel for the Japanese market that collects energy from the sun while still allowing the light to shine on through.“ ” Though it’s rated at a lowly 6.8 percent efficiency, the glass-like properties make it useful as a construction material (as shown in the balcony… Continue reading Sharp presents transparent solar panels

Another solar efficiency record : 43.5 %

As Treehugger reported last week, the Japanese company Sharp has broken another record : 43.5 percent of efficiency, to be compared with their previous record, 36.9% efficiency which had been reached in November 2011. Typical solar panels in the market today still have around 15 or 20 percent of efficiciency. But research is breaking records… Continue reading Another solar efficiency record : 43.5 %
