The ratio of the electric energy produced by a photovoltaic device (under one-sun conditions) to the energy from sunlight incident upon the cell.
The efficiency at which a specific technology converts the energy from a source (e.g. falling water, fossil fuel, wind, sunlight) into usable energy (see primary and consumer energy).
a convolution of the reflection coefficient and the energy-dependent negative charge fraction yield
The ratio of the electrical energy produced by a photovoltaic cell to the solar energy impinging on the cell.
The ratio of the energy produced by a photovoltaic device to the energy received or consumed expressed as a percentage. Solar panels are typically 9% to 14% efficient.
the amount of energy produced as a percentage of the amount of energy consumed.
The ratio of the electrical energy produced by a PV cell to the total solar energy striking the cell. Usually around 10%, but as high as 18%.
The ratio of the electricity energy produced by a photovoltaic cell (under full sun conditions) to the energy from incident sunlight on the cell.
The percentage of electricity that is created by a solar cell as compared to the amount of energy needed to generate that electricity.
