Solar-cell efficiency

OverviewFactors affecting energy conversion efficiencyComparisonTechnical methods of improving efficiencySee alsoExternal links

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. For example, a solar panel with 20% efficiency and an area of 1 m produces 2…
