A2A Solar Cells and Photovoltaic [1] (PV) cells are the same thing.
History of the PV
The effect was discovered in 1954 by scientists at Bell Labs (The research arm of Bell Telephone). Basically, when photons hit certain materials, some of the electrons are hit by the photons of light hitting the material and generate current flow, which can be used to sense light and generate electricity.
Efficiencies[2]
At the time Bell Labs discovered the PV, the efficiency was about 6%. By 1960, that had increased to about 14%, but was very expensive and typically used in space projects.
Most of the current type of PV in mass production are made from silicon. The efficiency of these cells in mass production currently max out around 21.6% of visible light converted to electricity. However, it is not limited to just visible light.
Future Efficiencies
In labs, they have produced cells up to about 45%, and the theoretical maximums are about 48% for silicon. All of this assumes you are not using optical lenses to focus light from a larger area onto a smaller PV. But some biological processes of bacteria and plants can achieve 100% conversion under certain conditions. This means that it may be discovered a way to mimic this economically in the future in a mass scale to provide energy.
