To understand efficiency of a solar panel, you must first understand its source of energy – the Sun. Sun emits energy in a form of light which is composed of photons. Each photon has different energy and wavelength range (from ultraviolet to infrared). Photons are used by photovoltaic cells in solar panels to convert.

Customer ServiceThis great development in the efficiency is not matched if the cost of the device is considered. The highly efficient PVs (mainly multi-junction solar cells) are prohibitively expensive [3], [4]. On the other hand, the efficiency of the most dominant technology in the market (i.e. Si) is 25% in the lab and less than 20% commercially.
Customer ServiceSolar-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.
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.
The power conversion efficiency of a solar cell is a parameter that quantifies the proportion of incident power converted into electricity. The Shockley-Queisser (SQ) model sets an upper limit on the conversion efficiency for a single-gap cell.
Theoretically, many models were used to estimate the maximum possible efficiencies of the solar cells. They can be categorized in two general families. The first category analyses are phenomenologically based on detailed balance of radiations between two-extended-level system.
The problem with solar cell efficiency lies in the physical conversion of sunlight. In 1961, William Shockley and Hans Queisser defined the fundamental principle of the solar photovoltaic industry.
Some thorough theoretical analyses with more restricted practical assumptions indicated that the limit is not far above the obtained efficiency . Currently, we are in the midst of the third generation solar cell stage.
