This 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 , . 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.
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.
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.
Efficiency limits for photovoltaic cells can be theoretically higher considering thermodynamic effects. For a solar cell powered by the Sun's unconcentrated black-body radiation, the theoretical maximum efficiency is 43% whereas for a solar cell powered by the Sun's full concentrated radiation, the efficiency limit is up to 85%.
The STC approximate solar noon at the spring and autumn equinoxes in the continental United States with the surface of the solar cell aimed directly at the sun (Solar Efficiency Limits). The limit is measured under certain assumptions. The solar cell must be made of only one type of homogeneous material.
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.

Why Is Solar Cell Efficiency Low?
Efficiency of solar panels represents how much of sunlight that hits a solar cell gets transformed into electricity. Some of the first solar panels had efficiencies between 8 to 10 percent. Other traditional sources of energy had efficiency of 40 to 55 percent with the combined cycle generators [2]. The competition was just unbalanced.
