In other words, the solar cell efficiency is obtained by dividing the solar cell output energy by the input energy from the sun [[45], [46]]. The sunlight''s wavelength, the cell temperature, recombination, and reflections are factors that govern the efficiency of a PV cell. For example, the higher the temperature of the cell, the lower its efficiency will be. The PV cell

The theory of solar cells explains the process by which light energy in photons is converted into electric current when the photons strike a suitable semiconductor device.The theoretical studies are of practical use because they predict the fundamental limits of a solar cell, and give guidance on the phenomena that contribute to losses and solar cell efficiency.
Power Degradation. Efficiency of solar cells and solar panels are known to decrease over time, outputting less energy every year.

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 efficiency is measured under carefully controlled conditions to compare the performance of different devices. The efficiency depends on the spectrum and intensity of the incident sunlight, as well as the temperature of the solar cell.
Solar cell efficiency depends on the spectrum and intensity of the incident sunlight and the temperature of the solar cell. In addition to reflecting the performance of the solar cell itself, these factors must be carefully controlled in order to compare the performance of one device to another.
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%.
Although not constituting a direct strategy to improve efficiency, thin film materials show a lot of promise for solar cells in terms of low costs and adaptability to existing structures and frameworks in technology. Since the materials are so thin, they lack the optical absorption of bulk material solar cells.
When the incoming radiation comes only from an area of the sky the size of the sun, the efficiency limit drops to 68.7%. Normal photovoltaic systems however have only one p–n junction and are therefore subject to a lower efficiency limit, called the "ultimate efficiency" by Shockley and Queisser.
