Solar-cell efficiency is the portion of energy in the form of sunlight that can be converted via photovoltaics into electricity by the solar cell. The efficiency of the solar cells used in a photovoltaic system, in combination with latitude and climate, determines the annual energy output of the system.
Solar cell efficiencies vary from 6% for amorphous silicon-based solar cells to 44.0% with multiple-junction production cells and 44.4% with multiple dies assembled into a hybrid package. Solar cell energy conversion efficiencies for commercially available multicrystalline Si solar cells are around 14–19%.
The highest research cell efficiency recorded in the chart is 47.1%, for a four-junction cell. Its interactive nature allows users to visualize the recent jump in conversion efficiencies for emerging technologies like perovskite solar cells. That contrasts with the steady improvement of silicon solar cell efficiency since the 1980s.
A chart of the highest confirmed conversion efficiencies for research cells for a range of photovoltaic technologies, plotted from 1976 to the present. The chart displays record research cell efficiencies for five major technologies: crystalline silicon cells, single-junction gallium arsenide cells, multijunction cells, thin films, and emerging PV.
“The format of the chart will soon change to include hybrid tandems.” The chart now includes the 33.9% world record efficiency achieved in November by Chinese manufacturer Longi for a perovskite-silicon tandem solar cell and the 27.09% efficiency achieved by the same company for a heterojunction back contact solar cell.

Energy conversion efficiency is measured by dividing the electrical output by the incident light power. Factors influencing output include spectral distribution, spatial distribution of power, temperature, and resistive load.
