Not all of the sunlight that reaches a PV cell is converted into electricity. In fact, most of it is lost. Multiple factors in solar cell design play roles in limiting a cell's ability to convert the sunlight it receives. Designing with these factors in mind is how higher efficiencies can be achieved. 1.

Photovoltaic cells are semiconductor devices that can generate electrical energy based on energy of light that they absorb.They are also often called solar cells because their primary use is to generate electricity specifically from sunlight, but there are few applications where other light is used; for example, for power over fiber one usually uses laser light.

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.

The process of directly converting sunlight into electricity without using a heat engine is known as photovoltaic conversion. The fundamental benefit of photovoltaic devices is that they are made as standalone systems, allowing them to provide outputs ranging from microwatts to megawatts.
C.J. Brabec, in Encyclopedia of Materials: Science and Technology, 2010 The ‘ultimate’ photovoltaic conversion efficiency of an ideal single junction solar cell at T c =0 K is only about 40% under concentrated light, as calculated by Shockley and Queisser (1961). This limitation arises from two basic phenomena occurring in such devices.
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.
