Photovoltaic Cells Compared

Photovoltaic Cells Compared

While every photovoltaic manufacturer and every research group that investigate the photovoltaic cell technology can claim that they have found the “best” technology, or that they have reached a new record in energy production – the truth is very hard to find.

IEEE and and tree independent labs: AIST, NREL & Fraunhofer have made for us an interactive chart that show the istory of record-breaking photovoltaic cells.
See the information as a pornographic or see bellow the full spreadsheet.

Cell Efficiency Chart

Solar cell efficiency is measured with respect to the standard reference spectra in IEC standard 60904-3 edition 3 at 25 °C.
1 sun = 1,000 Wm2
