Research Cell Efficiency Records

You are here

The National Renewable Energy Laboratory  maintains a plot of compiled values of highest confirmed conversion efficiencies for research cells, from 1976 to the present, for a range of photovoltaic technologies. This chart highlights cell efficiency results within different families of semiconductors: (1) multijunction cells, (2) single-junction gallium arsenide cells, (3) crystalline silicon cells, (4) thinfilm technologies, and (5) emerging photovoltaics.
