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%.
Ross and Hsiao reported that the efficiency cannot exceed 29% based on an ideal theoretical analysis, where entropy and unavoidable irreversibility place a limit on the efficiency of photochemical solar energy conversion.
The efficiency of a photovoltaic cell determines how much solar energy is converted into useful (electrical) energy and is determined by the maximum power Pm [27, 28] S. Manju, Netramani Sagar, in Renewable and Sustainable Energy Reviews, 2017
It depends on the material of the cell. In the case of Silicon, exposed to solar radiation (without concentrating it), 22% of the energy of the AM 1.5 spectrum does not have enough energy to create the pair eh; another 32% is lost because the photons have more energy than 1.11 eV. Therefore, only 49.6% of the energy (efficiency) could be converted.
In addition to reflecting the performance of the solar cell itself, the efficiency depends on the spectrum and intensity of the incident sunlight and the temperature of the solar cell. Therefore, conditions under which efficiency is measured must be carefully controlled in order to compare the performance of one device to another.
