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.
