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.
Short title: Best Research-Cell Efficiency Chart: Image title: National Renewable Energy Laboratory (NREL) 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.

The current world record for solar cell efficiency is 32.5 per cent – meaning nearly a third of solar radiation is converted into eletrical energy – which was achieved with a perovskite ...
That compares to 27% efficiency for crystalline silicon cells and around 21% for traditional commercial silicon solar panels, according to NREL. Cell efficiency refers to the percentage of solar ...
2008 - New record achieved in solar cell efficiency. Scientists at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) have set a world record in solar cell efficiency with a photovoltaic device that converts 40.8% of the light that hits it into electricity. However, it was only under the concentrated energy of 326 suns ...
The National Renewable Energy Laboratory projects that the levelized cost of wind power will decline about 25% from 2012 to 2030. [16] In fiscal year 2020, congressional appropriations for the Department of Energy contained $464.3 million for NREL. This total included the following amounts for its renewable energy technology programs: [17]
In 2017, a team of researchers at National Renewable Energy Laboratory (NREL), EPFL and CSEM (Switzerland) reported record one-sun efficiencies of 32.8% for dual-junction GaInP/GaAs solar cell devices. In addition, the dual-junction device was mechanically stacked with a Si solar cell, to achieve a record one-sun efficiency of 35.9% for triple ...
