The power conversion efficiency (η) is calculated as the numerical quotient of P max and the total integrated spectral irradiance (P o), giving η = P max /P o. It can be defined as a function of FF as:
The efficiency of an electrical power conversion process is not 100 percent due to energy losses as heat. An ideal conversion would have an efficiency of 100 percent, but in reality, some input power is used for the conversion process itself, resulting in less power at the output.
The efficiency of an electrical power conversion process is measured by dividing the output power in watts by the input power in watts and expressing the result as a percentage. In power electronics, the Greek letter eta (η) is used to represent efficiency.
Prashant K. Baviskar, Babasaheb R. Sankapal, in Energy Materials, 2021 The overall power conversion efficiency (η) of the PV cell is calculated from the short-circuit photocurrent density (Jsc), open-circuit photovoltage (Voc), FF of the cell, and the incident light intensity (Pin = 100 mW/cm 2).
Useful output energy is always lower than input energy. Efficiency of power plants, world total, 2008 Energy conversion efficiency (η) is the ratio between the useful output of an energy conversion machine and the input, in energy terms.
Energy can be divided into quantity and quality terms. For electric power, quantity and quality are described by current and voltage, respectively. The electric power efficiency of hydrogen fuel cells can be written as follows.
